Abstract (sommario):

Une bonne activité sportive améliore la santé, mais elle peut aussi être une source de blessure physique. Dés lors, la prise en charge médicale pourra s'accompagner d'une prise en charge psychologique. Nous présentons dans ce travail les modèles théoriques des réactions psychologiques à la blessure et une partie est spécifiquement consacrée à l'anxiété de re-blessure. Nous exposons, ensuite, des pistes pour améliorer l'accompagnement psychologique des patients comme la relaxation ou l'imagerie mentale. Nous présentons également une étude expérimentale présentant les effets de la relaxation et de l'imagerie sur différentes variables psychologiques comme l'anxiété de re-blessure ou les troubles de l'humeur. Ces résultats permettent de dresser quelques pistes pour les praticiens et la recherche dans ce domaine
A good sporting activity improves health, but it can also be a source of physical injuries. Therefore, medical care should be assisted with psychological care. We're presenting in this work the theoretical models of psychological reactions to injury and part is specifically devoted to the re-injury anxiety. We're explaining ways to improve psychological assisting of patients with methods such as relaxation or imagery. Then we'll present an experimental study about the effects of relaxation and imagery on psychological variables like re-injury anxiety and mood disturbance. These results provide to draw some ideas for practitioners and research in this area

Abstract (sommario):

L'anxiété dans la maladie de Parkinson (MP) est un symptôme non-moteur fréquent et invalidant dont la prise en charge est difficile. La faible connaissance des mécanismes impliqués est une limite à sa prise en charge. L'objectif de ce travail était d'identifier les mécanismes sous-jacents de l'anxiété liée à la MP, via une approche IRM cérébrale multimodale.Une revue systématique de la littérature portant sur les données d'imagerie dans l'anxiété liée à la MP a d'abord été réalisée, permettant de générer de premières hypothèses. Ensuite, plusieurs études incluant des analyses en IRM cérébrale structurale et fonctionnelle ont été menées chez des patients atteints de MP et présentant ou non une anxiété cliniquement significative. Nos analyses se sont focalisées sur le circuit de la peur, connu pour être impliqué dans les troubles anxieux, et le circuit cortico-striato-thalamo-cortical limbique, connu pour son implication dans les symptômes psycho-comportementaux de la MP.Nos résultats suggèrent que l'anxiété liée à la MP serait la conséquence d'un déséquilibre fonctionnel et structural entre ces deux circuits. Certaines structures communes, comme le thalamus, le striatum ou les noyaux du tronc cérébral, pourraient être des zones clés dont l'altération pourrait expliquer la forte prévalence de ces troubles dans la MP. D'autres travaux s'appuyant notamment sur les avancées technologiques en imagerie et sur de nouveaux concepts concernant la physiopathologie de la MP, seront nécessaires pour répondre à ces questions
Anxiety in Parkinson's disease (PD) is a frequent and disabilitating non-motor symptom. It is difficult to manage, partly due to a poor knowledge of the underlying mechanisms. The objective of this thesis was to identify the underlying mechanisms of PD-related anxiety, using multimodal brain MRI.A systematic review of the literature on imaging data in PD-related anxiety was first carried out, allowing the generation of initial hypotheses. Then, several studies including structural and functional brain MRI analyses were carried out in PD patients with or without clinically significant anxiety. Our analyses focused on the fear circuit, known to be involved in anxiety disorders and fear processing, and the limbic cortico-striato-thalamo-cortical circuit, known for its involvement in the neuropsychiatric symptoms of PD.Our results suggest that PD-related anxiety is the consequence of a functional and structural imbalance between these two circuits. Certain overlapping structures, such as the thalamus, the striatum or the brainstem nuclei, could be key areas whose alteration could explain the high prevalence of these disorders in PD. Further works based in particular on technological advances in imaging and new concepts concerning the pathophysiology of PD will be necessary to answer the remaining questions

Abstract (sommario):

Les troubles anxieux sont très répandus et représentent une lourde charge de morbidité. Cependant, malgré une abondante littérature sur la neuro-imagerie à l’échelle du groupe, des marqueurs cérébraux robustes de vulnérabilité ou de réponse thérapeutique peinent à émerger. Ces dernières années, les approches de prédiction à l’échelle individuelle utilisant l'apprentissage automatique sont devenues de plus en plus populaires dans la recherche en santé mentale, et certains résultats prometteurs ont été rapportés dans des études de neuro-imagerie à petite échelle (généralement avec Ntotal < 60 participants). Ces résultats n'ont pas encore été reproduits dans des échantillons plus importants et multisites. Le présent projet de doctorat impliquait l'utilisation de l'apprentissage automatique supervisé pour prédire prospectivement le développement de troubles anxieux chez les adolescents en utilisant un jeu de données longitudinales de la population générale, IMAGEN, ainsi que pour prédire la réponse au traitement psychothérapeutique chez les patients phobiques en utilisant le jeu de données SPIDER-VR. Avec les données IMAGEN, des analyses d'apprentissage automatique ont été réalisées à partir de questionnaires et de données neuroanatomiques d'adolescents non anxieux, afin de prédire le développement d'un futur trouble anxieux (N = 156) par rapport à un statut de contrôle sain (N = 424). L'étude a souligné le potentiel prédictif des données sociodémographiques et issues de questionnaires pour la prédiction de futurs troubles anxieux regroupés, et celui des volumes de matière grise pour la prédiction d'un trouble anxieux généralisé. Les mesures d'IRM fonctionnelle extraites d'une tâche de traitement émotionnel des visages n'ont pas produit de performance prédictive supérieure au niveau de chance. Avec les données SPIDER-VR, des analyses d'apprentissage automatique ont été menées pour prédire la réponse des patients phobiques des araignées (N = 190) à une session de thérapie d'exposition en réalité virtuelle, en utilisant des données de questionnaires, des données d'IRM structurelle et diverses mesures d'IRM fonctionnelle extraites d'une tâche de provocation des symptômes. Contrairement aux attentes, l'étude n'a pas confirmé le potentiel prédictif des données sociodémographiques et de questionnaires, ni des données de neuro-imagerie, à l'exception de la variance du signal BOLD qui a produit une performance prédictive modérée. Dans l'ensemble, ce travail de doctorat remet en question les résultats optimistes d'études antérieures à plus petite échelle sur la prédiction de l'anxiété par apprentissage automatique basé sur la neuro-imagerie. Néanmoins, les résultats corroborent le fait que des questionnaires faciles à administrer présentent une performance prédictive prometteuse pour la prédiction de l'apparition de l'anxiété et que l'IRM structurelle puisse apporter une valeur prédictive supplémentaire. Divers autres biomarqueurs de l'anxiété sont apparus dans la littérature avec le potentiel d'améliorer la précision des prédictions relatives à l'anxiété, et d'autres recherches multimodales utilisant des jeux de données à grande échelle ainsi qu'une méthodologie rigoureuse d'apprentissage automatique sont nécessaires pour atteindre l'utilité clinique
Anxiety disorders are highly prevalent and represent a heavy burden of disease. However, despite a large group-level neuroimaging literature, robust brain markers of vulnerability or therapeutic response struggle to emerge. In recent years, individual-level prediction approaches using machine-learning have become increasingly popular in mental health research, and some promising results have been reported in small-scale neuroimaging studies (usually with Ntotal < 60 participants). These prediction results have yet to be replicated in larger, multisite samples. The present doctoral project involved the use of supervised machine-learning to prospectively predict the development of anxiety disorders in adolescents using a longitudinal dataset from the general population, IMAGEN, as well as to predict the response to psychotherapeutic treatment in phobic patients using the SPIDER-VR dataset. With IMAGEN data, machine-learning analyses were conducted using questionnaire and neuroanatomical data of non-anxious adolescents, to predict the development of a future anxiety disorder (N = 156) vs. healthy control status (N = 424). The study supported the predictive potential of sociodemographic and questionnaire data for the future onset of pooled anxiety disorders, and of gray matter volumes for future generalized anxiety disorder onset. Functional MRI metrics extracted from an emotional face processing task did not yield any above-chance level predictive performance. With SPIDER-VR data, machine learning analyses were conducted to predict the response of patients with spider phobia (N = 190) to a virtual reality exposure therapy session, using questionnaire data, structural MRI data, and various functional MRI metrics extracted from a symptom provocation task. Contrastingly to expectations, the study did not support the predictive potential of sociodemographic and questionnaire data nor neuroimaging data, with the exception of BOLD signal variance which yielded moderate predictive performance. Overall, this doctoral work challenges optimistic results from earlier smaller-scale neuroimaging- based machine-learning prediction studies in anxiety. Nonetheless, findings substantiate that easy-to-administer questionnaires show promising predictive performance for anxiety onset prediction and that structural MRI might bring incremental predictive value. Various other anxiety biomarkers have emerged in the literature with potential to improve the accuracy of anxiety-relevant predictions, and further multimodal research using large-scale datasets alongside rigorous machine- learning methodology are needed in an effort to reach clinical utility

Abstract (sommario):

Au sein du circuit cortico-limbique, des régions complémentaires seraient impliquées soit dans l’évaluation soit dans la régulation des états affectifs. Cependant, la contribution respective de ces mécanismes «bottom-up» et «top-down» lors du traitement émotionnel reste à clarifier. Premièrement, nous avons validé un nouveau paradigme d’IRMf conçu pour dissocier les composants du circuit cortico-limbique, c.-à-d. le circuit dorsal cognitif entrecroisé avec le circuit ventral affectif. Nous avons trouvé que l’amygdale et ses connexions avec le circuit dorsal étaient engagées par le traitement émotionnel bottom-up. Le cortex cingulaire antérieur (CCA) dorsal et ses connexions avec le cortex préfrontal dorso-latéral (CPFDL) et l’amygdale étaient recrutés par la résolution top-down du conflit émotionnel. Le CPFDL et ses connexions avec le CCA dorsal étaient engagés par le contrôle attentionnel top-down. Puis, nous avons examiné l’impact de l’anxiété sur le circuit. Nous avons montré qu’une forte anxiété était associée à une activation plus importante du CCA en réponse au conflit émotionnel mais à une connectivité réduite entre CCA et CPFL. Enfin, nous avons examiné la variation d’activité et de connectivité fonctionnelle chez des patients schizophrènes. Chez les patients comparativement aux témoins, les processus bottom-up étaient associés à une interaction réduite entre l’amygdale et le CCA ventral et dorsal ainsi que le CPFDL. La résolution du conflit émotionnel entraînait une plus forte connectivité entre CCA dorsal et CCA ventral ainsi que le CPFDL. L’augmentation du contrôle attentionnel provoquait une connectivité plus importante entre le CPFDL et le CCA ventral
Within the cortico-limbic circuit, complementary regions are believed to be involved in either the appraisal or the regulation of affective state. However, the respective contribution of these bottom-up and top-down mechanisms during emotion processing remains to be clarified. First, we validated a new fMRI paradigm designed to dissociate the components of the cortico-limbic circuit, that is, the dorsal cognitive circuit intertwined with the ventral affective circuit. We found that the amygdala and its connections to the dorsal circuit was engaged by bottom-up emotional processing. The dorsal anterior cingulate cortex (ACC) and its connections to the dorsolateral prefrontal cortex (DLPFC) and amygdala, was recruited by top-down resolution of emotional conflict. The DLPFC and its connections to dorsal ACC was engaged by top-down attentional control. Secondly, we investigated the impact of anxiety on the circuit. We demonstrated that higher levels of anxiety were associated with stronger conflict-related activation in ACC but with reduced connectivity between ACC and LPFC. Finally, we examined the variation in functional activity and connectivity in schizophrenia patients. In patients compared to controls, bottom-up processes were associated with reduced functional interaction between the amygdala and both dorsal and ventral ACC as well as DLPFC. Top-down resolution of emotional conflict led to stronger functional connectivity between the dorsal ACC and both ventral parts of ACC and DLPFC. Increased top-down attentional control caused higher functional coupling between the DLPFC and ventral ACC

Abstract (sommario):

L’objectif de cette thèse visait d’une part à mieux comprendre le rôle des facteurs psychopathologiques dans le déclenchement, le déroulement et la récupération de l’épisode d’ictus amnésique idiopathique (IA) et d’autre part à éclaircir les mécanismes physiopathologiques à l’origine des troubles. Nos résultats montrent que les troubles psychopathologiques peuvent être considérés comme des facteurs de prédisposition au déclenchement de certains épisodes d’IA. D’autre part, nous avons tenté de mieux caractériser l’IA et nous avons ainsi mis en évidence que l’IA n’est pas seulement un trouble de mémoire, puisqu’il s’accompagne d’une augmentation du niveau d’anxiété et d’une altération de l’humeur pendant l’épisode aigu. Nous avons également démontré que l’anxiété et l’humeur peuvent affecter les performances mnésiques des patients après l’épisode. En effet, les patients les plus anxieux et les plus déprimés obtenaient des performances inférieures aux autres patients, plusieurs mois après l’épisode. Ces résultats suggèrent que les troubles psychopathologiques peuvent ralentir les processus de récupération des capacités mnésiques après un IA. Toutefois, il est peu probable que ces troubles psychopathologiques soient entièrement responsables des perturbations mnésiques persistantes. Notre dernière étude confirme cette hypothèse puisque nous avons observé, grâce à l’IRM, une légère atrophie bilatérale des lobes temporaux internes incluant les deux hippocampes. Cette thèse a donc permis de souligner l’importance des facteurs psychopathologiques dans l’IA et leur interaction avec le fonctionnement mnésique

Abstract (sommario):

Résumé : Lors du retour au sport, les sportifs blessés sont exposés à des émotions et cognitions négatives spécifiques. Ce vécu psychologique a donné lieu à l’émergence du concept d’anxiété de re-blessure, dont les conséquences portent également sur la performance et la santé physique du sportif au vu du risque accru de re-blessure qui y est associé. Si certains travaux scientifiques récents ont permis d’améliorer la prédiction de l’anxiété de re-blessure ainsi que d’évaluer l’efficacité d’interventions psychologiques visant à la réduire, de nombreux domaines d’étude restent à approfondir en lien avec ce concept. Ce travail doctoral, structuré des articles scientifiques rédigés et soumis pendant la thèse ainsi que de ceux qui pourront en découler de façon prioritaire, proposera donc d’étudier le concept d’anxiété de re-blessure en référence à 5 objectifs complémentaires. Le premier chapitre de ce travail présentera une revue systématique de littérature visant à mieux identifier les déterminants de l’anxiété de re-blessure et des autres concepts proches, tout en précisant leurs définitions. Cette revue souligne l’importance de privilégier le concept d’anxiété de re-blessure pour décrire les réactions psychologiques du sportif reprenant la pratique sportive après blessure. Le second chapitre portera sur l’adaptation et une validation en langue française d’un outil de mesure de l’anxiété de re-blessure. L’étude de la structure factorielle de l’outil permet, au-delà du score global issu du questionnaire, l’identification de trois sous-dimensions : la peur de se re-blesser, l’anxiété de contre-performance et les manifestations anxieuses. Le troisième chapitre proposera d’étudier les déterminants de l’anxiété de re-blessure à l’aide d’analyses de régression et de modèles de médiation et de modération. Les résultats montrent que le stress, la symptomatologie anxieuse et le genre prédisent l’anxiété de re-blessure de façon directe, mais également indirecte au vu des effets médiateurs et modérateurs traduisant leurs interactions avec d’autres caractéristiques psychologiques. L’utilisation d’un modèle croisé décalé permet également de montrer le rôle du stress dans la prédiction de l’anxiété de re-blessure dans une perspective longitudinale. Le quatrième chapitre proposera de tester l’existence de profils psychologiques liés à l’anxiété de re-blessure. Les analyses en clusters réalisées mettent en évidence quatre profils différents, au sein desquels apparaissent deux profils caractérisé par la présence de l’anxiété de re-blessure et d’autres émotions négatives (l’un à un niveau modéré, l’autre à un niveau élevé), un profil caractérisé par un faible niveau d’anxiété de re-blessure, et un dernier profil caractérisé par un niveau d’anxiété de re-blessure « intermédiaire » et surtout par le manque de confiance que le sportif accorde à la partie du corps blessé. Enfin, le cinquième chapitre présentera le travail d’élaboration et de mise en place ainsi que l’évaluation de l’efficacité d’une intervention d’imagerie mentale de type Visuo-Motor Behavior Rehearsal (VMBR) proposée à des sportifs ayant subi une intervention chirurgicale du ligament croisé antérieur dans le cadre d’un protocole randomisé contrôlé. L’intervention s’avère efficace sur la réduction de l’anxiété de re-blessure, du stress et de la douleur. Par ailleurs, elle permet de renforcer d’autres facteurs protecteurs tels que l’optimisme et la recherche de soutien social. L’intervention permet également aux athlètes de revenir plus rapidement au sport que ceux ne l’ayant pas reçue. La synthèse générale de ce travail proposera de déterminer les conditions de généralisation des principaux résultats obtenus tout en identifiant les perspectives d’applications rendues possibles dans le champ sportif dans la prise en charge d’autres problématiques sportives mais également auprès d’autres populations confrontés à des enjeux de performance ou exposés à des risques de blessure
Abstract : When returning to sports, athletes are exposed to specific negative cognitions and emotions. One of these negative emotions was named re-injury anxiety. The consequences of re-injury anxiety could lead to an impact on performance and physical well-being, increasing the risk of re-injury. The psychological aftermath of re-injury anxiety have been depicted with increasing interest in literature, and interventions decreasing this specific emotion, many gaps in literature remain to be developed. The purpose of this doctoral work, with published scientific articles, will study the concept of re-injury anxiety in reference to five complementary objectives. The first chapter of the thesis will present a systematic review of the literature, highlighting the factors of re-injury anxiety and other close concepts. This review of literature will demonstrate the importance in prioritising the concept of re-injury anxiety to describe psychological reactions when an athlete return to sport after an injury. The second chapter will focus on the adaptation and a validation in French language of a measuring tool for re-injury anxiety. Exploratory and confirmatory factorial analysis allowed us to identify three subscales of this specific anxiety : the latter will be named : fear of re-injury, performance anxiety and signs of anxiety. The third chapter will propose the study of the factors of re-injury anxiety with regression analysis, mediation and moderation models. The results showed that stress, anxious symptomatology and gender were directly predicting re-injury anxiety, and also indirectly with mediating and moderating effects, describing their interactions with other psychological characteristics. Using cross-lagged models allowed us to identify the signification of stress in predicting re-injury anxiety in a longitudinal perspective. In the fourth chapter, we will investigate the psychological cluster related to re-injury anxiety. Cluster analysis highlighted four different profiles with 2 specific profiles characterised by high level of re-injury anxiety and other negative emotions (i.e., one with moderate level, and one with very high level of re-injury anxiety). An other profile was characterised by a low re-injury anxiety level, and the last profile was characterised with average re-injury anxiety especially with very low knee confidence. Finally, the fifth chapter will discuss the psychological interventions which can be proposed to athletes expressing re-injury anxiety. The fifth part of this work will present the implementation in a rehabilitation center of a controlled randomised interventional protocol based on mental imagery like Visuo-Motor Behavior Rehearsal (VMBR) on athletes who injured at anterior cruciate ligament. The intervention turns out to be efficient on the reduction of negative effects caused by the injury such as re-injury anxiety, stress but also pain. Besides, it allows the increased mobilisation of protective factors such as optimism and social support seeking. Resorting to a VMBR-like intervention also allows athletes to return to sport faster than those who didn’t. The general synthesis of this thesis will offer to generalise the principal results obtained while identifying the perspectives of application of the results in other types of interventions, contexts, or in other populations

The aim of this work is to study anxiety and apathy in treatment resistant depression. These clinical factors and its imaging correlates will be tested in prediction of outcome in a 6-months follow-up. Original data were retrieved in LONGIDEP cohort. This is a prospective study conducted in routine care. Patients suffering from a mood depressive episode benefited from a clinical, neuropsychological and brain imaging. They were assessed once again at 6 months. Our study has shown that 1) apathy in depression is associated with specific clinical and pathophysiological patterns, 2) categorical and dimensional approach of anxiety in treatment resistant depression are not convergent. This latter population exhibited higher brain perfusion of centro-medial amygdala, 3) trait anxiety, cognitive patterns of visuospatial memory were predictive of pejorative outcome. Structural abnormalities in key regions involved in emotion regulation were associated with pejorative outcome of depression. Only anxiety was involved in outcome of depression. The link between anxiety and motivation should be studied in further works

Abstract (sommario):

Les symptômes psychoaffectifs anxieux et dépressifs infra-cliniques sont fréquents chez les personnes âgées et sont associés à un risque accru de développer une démence et de progresser d’un stade prédémentiel à un stade démentiel. Cependant, ils pourraient également être des symptômes associés à une démence, et pourraient constituer une manifestation clinique de la pathologie sous-jacente. L’objectif de cette thèse était de contribuer à une meilleure compréhension des liens entre symptômes anxieux et dépressifs et les modifications cognitives et cérébrales structurales, fonctionnelles et moléculaires typiques de la maladie d’Alzheimer (MA), à la fois dans le vieillissement normal et au cours de cette pathologie. Nos résultats montrent que des symptômes anxieux élevés sont associés à un volume de substance grise plus bas chez les sujets âgés cognitivement sains, et ce uniquement chez les femmes. Cette même association est présente chez les sujets Subjective Cognitive Decline (SCD) recrutés dans la population générale, et montre une vulnérabilité accrue aux maladies neurodégénératives liées à l’âge, telles que les démences. Chez les SCD ayant consulté pour leur déclin cognitif subjectif, des symptômes dépressifs élevés sont associés à une charge amyloïde plus importante dans le cerveau, et donc à un risque accru de développer une MA, tandis que chez les sujets Mild Cognitive Impairment (MCI) et MA amyloïde positifs, ils sont liés à une meilleure cognition et conscience de ses propres troubles. Les symptômes psychoaffectifs semblent donc avoir un rôle évolutif au cours du passage du vieillissement normal au vieillissement pathologique, d’abord manifestation d’une vulnérabilité cérébrale, puis manifestation d’une pathologie sous-jacente et d’un risque de développement de MA, ils sont au contraire un marqueur de préservation chez les patients présentant un déclin cognitif (MCI et MA)
Subclinical psychoaffective symptoms of anxiety and depression are common in the elderly and are associated with an increased risk of developing dementia and progressing from a pre-dementia stage to a dementia stage. However, they could also be symptoms associated with dementia and could be a clinical manifestation of the underlying pathology. The aim of this thesis was to contribute towards a better understanding of the links between anxiety and depressive symptoms and Alzheimer's disease (AD) hallmarks, including cognitive, structural, functional and molecular modifications, both in normal aging and during the course of this pathology. Our results show that higher anxiety symptoms are associated with lower grey matter volume in cognitively healthy elderly subjects, but only in women. This same association is present in all Subjective Cognitive Decline (SCD) participants recruited from the general population, and shows an increased vulnerability to age-related neurodegenerative diseases such as dementia. In Subjective Cognitive Decline (SCD) subjects, high depressive symptoms are associated with greater amyloid load in the brain, and thus an increased risk of developing AD, while in amyloid-positive Mild Cognitive Impairment (MCI) and AD subjects, they are related to better cognition and awareness of their cognitive deficits. Psychoaffective symptoms thus seem to have an evolving role during the transition from normal aging to pathological aging; they first manifest a brain vulnerability, then an underlying pathology and a risk of developing AD, and then are a marker of preservation in patients with cognitive decline (MCI and AD)

Abstract (sommario):

Anxiety is a clinically significant feature of bipolar spectrum disorders [BP]. The. rate of anxiety symptoms and/or comorbid anxiety diagnoses is high, and it contributes to worse outcomes in a range of domains. There is an accumulation of evidence that psychological therapy is effective for anxiety, which is not so for BP. Mental imagery is implicated in the maintenance of anxiety and is a promising avenue of research in BP. A cognitive model of bipolar disorder posits that imagery is an emotional amplifier in mania and anxiety. Paper A presents a systematic review of the literature of psychological therapies for anxiety in BP. Twenty-two studies were identified, though no formal synthesis was possible. Preliminary data for CBT for obsessive compulsive disorder, generalised anxiety disorder, and post-traumatic stress disorder in a BP population are promising, and further research is warranted. Furthermore, the addition of an anxiety module to CBT for BP effectively reduces anxiety, and may have additional benefits in other domains. Pilot research applying other evidence-based CBT treatments for comorbid anxiety is indicated, as are RCTs for CBT for cyclothymia and rapid cycling BP. The addition of an anxiety module may Improve the effectiveness of psychological therapy for BP, further review and research is necessary to explore this. Paper B presents an empirical study, com paring imagery processes in adults with BP (currently euthymic), mixed anxiety disorders, and non-clinical controls. Genera imagery use, intrusive and deliberate prospective imagery, and characteristics of image ' during different mood states are explored. People with anxiety have high levels 0 general imagery use and intrusive prospective imagery. Unlike the clinical groups, the control group appears to have a bias against negative imagery in a deliberate prospective imagery task. Retrospective report of mental imagery during past low, anxious and high mood states gives partial support to the imagery as an emotional amplifier theory, and similarities between the clinical groups may illuminate the high rates of comorbidity. Future research is discussed.

Abstract (sommario):

The purpose of this study was to measure the effects of an imagery session on intercollegiate female swimmers' precompetitive state anxiety levels and on perceptions of anxiety. A switched replication design was utilized in which twenty-two female intercollegiate swimmers were administered the the Competitive State Anxiety Inventory2, CSAI-2 (Martens, Burton, Vealey, Bump, & Smith, 1990) and the Competitive Anxiety Perception Scale, CAPS, (Murray, 1989) weekly over the course of five weeks. Subjects were then randomly exposed to an imagery session during this period. Although descriptive data showed decreases in subjects' levels of A-state, a 2x2 ANOVA revealed no significant differences between subjects' PRE and POST scores. The observed decreases in A-state, although nonsignificant at the .05 level, warrants future research with a larger sample size. Additionally, the nonsignificant change in CAPS suggested that one's perceptions of anxiety may be learned at an early age and, therefore, not easily modified. It is suggested that future researchers attempt to identify those factors which mediate perceptions of anxiety.

Abstract (sommario):

Psychology
Ph.D.
Social anxiety disorder (SAD) is characterized by an intense fear of negative evaluation from others in social and/or performance situations. Research has demonstrated that socially anxious individuals' post-event processing, or post-mortem review of social situations, often affects their levels of anxiety, negative emotions, interpretations, and memories of events (Brozovich & Heimberg, 2008). Furthermore, research has shown that processing negative descriptions using imagery is more emotion-evoking than semantic processing of the same material (Holmes & Mathews, 2005; Holmes & Mathews, 2010). The present study investigated post-event processing involving mental imagery and its effects on mood, anxiety, and potentially biased interpretations of social and nonsocial events. Socially anxious and non-anxious participants were told they would give a 5 min impromptu speech at the end of the experimental session. They were then randomly assigned to one of three manipulation conditions: post-event processing imagery (PEP-Imagery), post-event processing semantic (PEP-Semantic), or a Control condition. In the post-event processing conditions, participants recalled a past anxiety-provoking speech and thought about the anticipated speech either using imagery (PEP-Imagery) or focusing on their meaning (PEP-Semantic). Following the condition manipulation, participants completed a variety of affect, anxiety, and interpretation measures. Consistent with our predictions, socially anxious individuals in the PEP-Imagery condition displayed greater anxiety than individuals in the other conditions immediately following the induction and before the anticipated speech task. Socially anxious individuals in the PEP-Imagery condition also interpreted ambiguous scenarios in a more socially anxious manner than individuals in the Control condition. The impact of imagery during post-event processing in social anxiety and its implications for cognitive-behavioral interventions are discussed.

Abstract (sommario):

People with high levels of social anxiety often experience spontaneous observer perspective images of themselves while anticipating, taking part in, or recalling, social situations. These images are usually negatively distorted, and yet are often taken by the anxious person to be an accurate representation of their performance. Such images are thought to be cognitively demanding for the socially anxious person, drawing their attention to aspects of themselves which they perceive as deficient. Additionally, the images prevent socially anxious people from attending to the situation as it genuinely appears, and can form the basis of socially anxious people's post-event review of social situations. The first study in this series presents qualitative findings from an interview study and demonstrates differences between the content of both observer and field perspective images in high and low socially anxious people. The second set of studies uses experimental methods to assess the intrapersonal effects of observer and field perspective images and demonstrates that while cognitive aspects of social anxiety such as negative thoughts were not affected by imagery, more emotional aspects such as discomfort were. Additionally, these studies showed that field perspective imagery was particularly beneficial for low socially anxious people's opinions of interaction quality, in a way that did not appear to be the case for the high anxious participants. The final set of studies examines more interpersonal outcomes of imagery, and demonstrates that overall, observer perspective images led to negative outcomes for both high and low socially anxious people, as well as the mid-anxious people with whom they conversed. Additionally, imagery was shown to have an effect on the social goals that people selected in anticipation of a social interaction. Overall, it is concluded that observer perspective imagery has a range of negative outcomes on both inter and intrapersonal aspects of social anxiety. Additionally, it is suggested that field perspective images among socially anxious people may sometimes contain negative information. Results are discussed in the context of existing models of social anxiety and imagery, and of potential implications for treatment approaches.

Abstract (sommario):

Guided imagery, a therapeutic technique in which a healer directs an individual to visualize a scene or sensations, has existed for millennia and is often used within healthcare settings today. A small, though growing number of studies among clinical samples demonstrate that guided imagery produces positive effects such as decreased pain and anxiety. Few studies have dismantled this intervention in order to isolate its active ingredients, and even fewer studies have determined for whom this intervention works. The current study sought to address these gaps in the literature by examining the effects of guided imagery on mood and anxiety among a college sample. The effects of a single session of non-directive guided imagery were examined through a repeated measures, pre-test post-test design with three experimental conditions. Multivariate analysis of data from 107 adults showed that following a distress induction, guided imagery significantly decreased anxiety and negative affect. However, guided imagery did not produce significantly greater changes in mood and anxiety than quiet rest or attention control conditions as hypothesized. Individual difference variables hypothesized as moderators (trait absorption, imagery vividness, imagery control) did not predict outcome; however, self-reported engagement in the experimental conditions predicted magnitude of change in outcome. The discussion outlines potential reasons for these unique findings as well as clinical implications and future directions for research.

Abstract (sommario):

Precompetitive anxiety (PCA) is problematic for young gymnasts and may have an influence on a multitude of factors like self-confidence, perceived level of self-efficacy, and athlete's performance in a competition. The objective of this 2-part study was to discover how earlier competitive experience influences the young gymnasts' level of anxiety, perception of control, and self-efficacy. An additional goal was to explore the potential impact of Guided imagery (GI) and Autogenic training (AGT) in reducing precompetitive anxiety. In the first study, 80 USAG Junior Olympic female gymnasts between the ages of 7 and 16 (40 compulsory level and 40 optional level) participated. The purpose was to test differences in levels of PCA, locus of control, and self-efficacy among optional level and compulsory level gymnasts. An independent samples t test and a Mann-Whitney nonparametric test showed that optional level gymnasts had higher cognitive anxiety, lower confidence level, and higher internal locus of control compared with compulsory level gymnasts, with no significant mean difference in somatic anxiety and self-efficacy. For the second study, 30 participants were divided into 3 treatment groups: (a) AGT group, (b) GI group, and (c) control group. Results of repeated measure ANOVAs revealed that mean anxiety scores decreased over time for the autogenic group as compared to the control and guided imagery group. The internal LOC mean scores were lower for the autogenic group, compared to the other groups, but internal locus of control did increase over time for the autogenic group. The social significance of this study suggests that enhanced performance and enjoyment in sports may allow athletes to remain active in sports while teaching them life-long strategies to reduce anxiety and stress in their lives.

Abstract (sommario):

Background and aims Social anxiety is common in people with psychosis. Recent evidence suggests that cognitive behavioural interventions can be used with this population to reduce distress and increase functioning. Imagery rescripting is effective for a range of psychological problems including social anxiety. This study aimed to investigate whether imagery rescripting is effective for social anxiety in people with psychosis. Method A single case series, multiple baseline design was used. Ten participants were recruited from Early Intervention in Psychosis (EIP) and Integrated Delivery Team (IDT) services in Norfolk and Suffolk. The intervention was replicated from previous work in the social anxiety field (Wild et al., 2008; Wild & Clark, 2011). Throughout the study participants completed measures related to social anxiety, beliefs, memory and imagery, psychotic symptoms, depression, social functioning and quality of life. Each participant attended seven sessions including a one month follow-up assessment. Data were analysed using visual inspection and the calculation of reliable and clinical change. Exploratory group statistics and effect sizes were also calculated. Results Five participants achieved reliable and clinical change in social anxiety and were classified as ‘recovered’ (Wise, 2004). Improvements in belief, memory and imagery ratings were observed for most participants following imagery rescripting. Psychotic symptoms, depression, social functioning and quality of life remained largely stable. Those who didn’t recover had more complex needs or comorbid difficulties. Group Imagery rescripting for social anxiety in psychosis D. Heavens iii analyses revealed significant improvements and medium to large effect sizes. However, this should be interpreted with caution due to the small sample size. Conclusion The study offers some support for the use of imagery rescripting for social anxiety in people with psychosis. Those with less complex presentations are likely to benefit most and it may offer a brief yet effective intervention for these individuals. Those with complex difficulties may require longer and more intensive input.

Abstract (sommario):

This study was designed to investigate the effects of Relaxation, Positive Suggestion and Success Imagery (RSI) on locus of control and scores on teacher-made exams in an undergraduate college population. As well as to investigate interactions between locus of control and the exam scores. The sample, composed of 52 females and 2 males ranging in age from 18-47, confirmed previous findings that women in college do not show an interaction between locus of control and grades. Furthermore, RSI did not appear to significantly change locus of control or exam scores for the whole sample. However, the data suggests RSI to effectively change locus of control and grades with the younger aged students, inferring that an internal locus of control is easier to develop and grades are easier to influence in younger students with this procedure.

Abstract (sommario):

Social anxiety disorder (SAD) involves persistent and excessive fear of negative evaluation or judgement in social/performance situations. The current thesis aimed to explore self-focused attention in SAD, which is considered a key maintaining feature in cognitive models of the disorder. This thesis sought to investigate the nature of self-focused attention, and to examine the efficacy of interventions which may reduce the negative impact of this process. The present thesis comprises two main parts. Part 1 of this thesis focused on ruminative self-focus, investigating the impact of different types of self-focus and exploring the efficacy of mindfulness and acceptance-based treatments for SAD. Hence, literature reviews 1 (chapter 2) and 2 (chapter 3) reviewed theoretical models and empirical evidence for self-focused processes in SAD, and empirical evidence for the impact of mindfulness and experiential self-focus on social anxiety. In addition, a systematic literature review of mindfulness and acceptance-based interventions for SAD was conducted (chapter 4), and suggested that such treatments may not be the most effective first-line intervention for the disorder. Empirical study 1 (chapter 5) further explored the impact of experiential compared to analytic self-focus among SAD individuals (n = 40) and non-clinical controls (n = 40). Contrary to expectations, results indicated that analytic self-focus may be adaptive for individuals with SAD, whereas experiential self-focus may be maladaptive. Part 2 involved a shift to focusing on negative self-referential imagery that occurs during self-focused attention in SAD, and is linked to aversive social experiences. Hence, literature review 3 (chapter 6) examined evidence for the role of key environmental factors in the aetiology of SAD, including the impact of aversive social experiences on the development of negative self-imagery. Empirical study 2 (chapter 7) was an interview-based study that extended current aetiological literature in SAD by exploring the relationship of various types of trauma with SAD development and maintenance. Outcomes suggested that early relational trauma may be a key proximal cause of SAD onset, leading to the development of negative beliefs and imagery that subsequently maintain the disorder. Thus, empirical study 3 (chapter 8) investigated the efficacy of imagery rescripting for SAD, an intervention aiming to alter negative meanings associated with memories of distressing experiences.Results provided support for the benefits of imagery rescripting in the treatment of SAD, yielding large reductions in trait social anxiety, equivalent to cognitive restructuring, and greater than a no treatment control. Hence, this thesis provides support for cognitive models of SAD, extends understanding of aetiological and maintaining factors in the disorder, and supports the use of imagery rescripting in the treatment of social anxiety. Empirical findings are comprehensively discussed, including clinical implications, limitations, and avenues for future research.

Abstract (sommario):

Twenty-four anxiety disorder subjects. 12 simple phobics and 12 panic disorders with agoraphobia, were assessed for physiological response (SCL, HR and EMG) to phobic imagery scripts. Subjects were instructed to image during tape-recorded scripts of standardized neutral (Neutral) and personally relevant fear (Phobic) scripts. All scripts contained both stimulus and response cues; however, subjects were presented four versions of a script which varied in response cue (propositional) content and presentation style: a version presented non-interactively which contained no cognitive cues (meaning propositions), a version presented non-interactively which contained cognitive cues, a version presented interactively which contained no cognitive cues, and a version presented interactively which contained cognitive cues. Both diagnostic groups produced significantly increased HR and SCL in response to Phobic scripts which contained cognitive cues and were presented interactively. Phobic Scripts which contained cognitive cues and were presented non-interactively produced significantly increased arousal only in the panic disorder group as measured by HR. Simple phobics also responded with significantly increased SCL to Phobic scripts presented interactively with no cognitive cues. Neither diagnostic group responded with increased arousal to the Phobic script presented non-interactively with no cognitive cues. Contrary to previous research, these results indicate that subjects with panic disorder with agoraphobia are capable of producing significantly increased physiological arousal in response to phobic imagery. The crucial importance of imagery script content and presentation style are highlighted by the results. Furthermore, the current investigation differed from previous investigations in that the parameters of an actual therapy session were more closely approximated by having the subjects image during script presentation rather than subsequent to script presentation. Finally, frontalis EMG did not prove to be a sensitive measure of anxiety in these subject populations pointing to the need for multiple channels of physiological measurement. Implications for content and methodology of future research studies in this area are discussed.

Abstract (sommario):

Research clarifying whether silent warm-up is possible and what constitutes a warmed-up voice is lacking. The acoustic correlates of a warmed-up voice are not clear, and perceptual correlates have centred on singers’ rather than both singers’ and listeners’ perceptions. This thesis therefore investigates acoustic and perceptual changes following vocal warm-up and breathing imagery, and whether breathing imagery may serve as a silent warm-up for singers. The literature review covers the acoustic and perceptual factors critical to optimal tone quality in singing, and the challenges of vocal assessment. It presents an historical survey of imagery and discusses the role of imagery in singing. It also investigates the relationship between optimal performance and vocal warm-up. As both imagery and warm-up for the voice are lacking thorough investigation, the review is supplemented with findings from sports psychology and sports medicine. In study 1, singers were recorded before and after three non-vocal 25 minute tasks. One task involved imagery of the breath directed upwards and downwards as far from the larynx as possible. Such imagery has played an important role in voice teaching since at least the 16th century. Another 25 minute task used Braille script as employed in the reading of music by the visually impaired. This provided the opportunity for the singer to engage in tactile, kinaesthetic and visual imagery related to music yet unrelated to breath function. A third task was a non-imagery breath-related activity that required the completion of a cloze passage about breath function for singers. In study 2, singers were recorded before and after a 25 minute vocal warm-up. The singers’ vocal signals were acoustically analysed for pre- to post-test changes in vibrato rate, vibrato extent and sound pressure level. Singer-subjects self-assessed their performances, and listener-judges perceptually rated the vocal samples presented in a fully randomised block design. Acoustic results for both breathing imagery and vocal warm-up produced three notable changes in vibrato rate: (i) more regularity in the cyclic undulations comprising the vibrato rate of a note, (ii) more stability in mean vibrato rates from one sustained note to the next, and (iii) a moderating of excessively fast and excessively slow mean vibrato rates for solos. The alternate imagery task based on Braille music code produced slower, less regular vibrato rates. This may have been due to the singers becoming too relaxed, as links are sometimes noted between imagery and relaxation. The non-imagery cloze passage task produced no significant change in vibrato from pre-test to post-test. Singers indicated that they sang better and felt warmed up after both the breathing imagery and vocal warm-up. The majority of listener-judges, however, concurred only in cases where the singer’s pre-test vibrato rate was either the fastest for the group, the slowest for the group or the most unstable for the group. Unlike vibrato rate, vibrato extent showed no consistent patterns of change acoustically as a result of any intervention. This thesis attempts to broaden our understanding of the relationships between imagery, warm-up and vibrato change. The findings support the use of vibrato analysis in the investigation of pedagogical practices. Furthermore, they indicate that change in the quality of vibrato, which impacts on tone quality, is central to both vocal warm-up and the long-standing use of directional imagery by singers. The findings of these studies may have direct bearing on teaching practice, physical and mental preparation, and the quality of vocal performance.

Abstract (sommario):

Anxiety is one of the most studied research topics in sport psychology literature (Guillen & Sanchez, 2009); however, even though the Olympics are considered to be one of the most pressure-filled sporting events (Birrer, Wetzel, Schmidt, & Morgan, 2012), to date there has been no research aimed specifically at investigating Olympic athletes’ competitive state anxiety and its impact on subsequent performance. Furthermore, according to Nesti (2011), in order to support athletes in dealing with their experience of anxiety, researchers must turn towards the phenomenological, real-lived experience of the athlete to uncover what might best support positive anxiety management and interpretation in competition. The purpose of this study, therefore, was to respond to the gap in Olympic athlete anxiety research by examining the phenomenological experience of competitive state anxiety for female beach volleyball players at the 2012 London Olympics. Six in-depth, phenomenological interviews were conducted with these Olympic female beach volleyball players. Results indicated that, while all athletes in this study experienced anxiety at the 2012 Olympics, it was not the reduced intensity of anxiety that positively impacted their performance but rather the athletes’ ability to recognize, manage, and positively interpret their anxiety. In addition, it was shown that self-confidence further buffered the potentially negative impacts of anxiety. It is recommended that future research focus on extending phenomenological anxiety research to other sports and genders, and to specifically examine the impact of trait anxiety, team dynamics, and the experience of flow on athletes’ anxiety interpretation.

Abstract (sommario):

Les militaires canadiens sont souvent confrontés à des situations stressantes et une partie de ceux-ci rapportent avoir des troubles du sommeil et faire des cauchemars. Depuis 2006, un traitement basé sur l’Imagery Rehearsal Therapy (IRT) nommé « groupe de traitement du sommeil » (GTS) est offert à la base de Valcartier pour traiter les troubles du sommeil et les cauchemars. Le GTS intégral inclut un volet psychoéducatif (une séance) et un volet traitement des cauchemars (deux séances). Les militaires aux prises avec un trouble du sommeil qui ne font pas de cauchemars sont dirigés vers le volet psychoéducatif du GTS donné seul (une séance). La présente étude a pour but d’évaluer l’efficacité du GTS auprès des militaires canadiens et poursuit quatre objectifs de recherche. Le premier est d’évaluer l’effet de la participation au GTS intégral sur le sommeil et les cauchemars. Le deuxième objectif est d’évaluer l’effet de la participation au volet psychoéducatif donné seul sur le sommeil. Le troisième objectif est d’évaluer l’effet de la participation au GTS intégral sur les symptômes associés à l’état de stress post-traumatique (ESPT), à l’anxiété et à la dépression. Enfin, le dernier objectif est d’évaluer l’effet de la participation au volet psychoéducatif donné seul sur les symptômes d’ESPT, d’anxiété et de dépression. L’échantillon de 37 militaires est réparti en quatre groupes. Deux groupes sont formés de participants liés au GTS intégral, soit un groupe expérimental (11 participants) et un groupe contrôle (trois participants), et deux groupes sont formés de participants liés à la psychoéducation donnée seule, soit un groupe expérimental (17 participants) et un groupe contrôle (six participants). Les groupes contrôle sont formés de participants sur la liste d’attente du GTS. Les mesures (prétest et post-test) incluent des agendas du sommeil (qualité du sommeil, nombre d’heures de sommeil, nombre et intensité des cauchemars) et trois questionnaires : PCL C (symptômes post-traumatiques), IDB-II (symptômes dépressifs) et IAB (symptômes d’anxiété). Les dossiers médicaux des participants ont aussi été consultés (données sociodémographiques et traitements psychothérapeutiques et pharmacologiques). Étant donné la taille limitée de l’échantillon, des tests non paramétriques (p. ex. test de Wilcoxon, etc.) ont été effectués afin de vérifier les changements entre le prétest et le post-test et pour comparer les groupes expérimentaux aux groupes contrôle. À la suite du GTS intégral, une amélioration significative de la qualité du sommeil et une diminution significative du nombre de cauchemars ont été rapportées, et ces améliorations sont significativement supérieures à ce qui est observé après le passage du temps. On observe aussi une augmentation significative du nombre d’heures de sommeil et une diminution significative de l’intensité des cauchemars à la suite du GTS intégral. Après la psychoéducation donnée seule, les résultats indiquent une augmentation significative du nombre d’heures de sommeil et une amélioration significative des symptômes dépressifs. Le GTS nécessite peu de temps et peu de ressources. Sachant que plusieurs militaires canadiens ont un problème de sommeil ou de cauchemars, les résultats de la présente étude indiquent que le GTS peut être une solution efficiente pour traiter les troubles du sommeil et les cauchemars.

Abstract (sommario):

While many studies have examined the effects of mental training programs on anxiety and concentration as they pertain to performance, none have examined the effects simultaneously as they relate to performance. Few studies have examined mental training programs, especially individualized mental imagery scripts, as they relate to the athlete's attentional profile and level of trait anxiety. The purpose of this study was to determine if a mental training program alters attentional profiles and trait anxiety. Additionally, this study determined if a mental training program had a transfer effect on performance. The following null hypotheses were examined: 1) There would not be a significant difference in attentional profiles before or after a mental training program; 2) there would not be a significant difference in trait anxiety scores before or after a mental training program; 3) there would not be a significant difference in an athlete's performance before or after a mental training program. The subjects (N = 20) in this study were comprised of Ball State University Women's Softball members. The age range of the subjects was between 18 and 23. The instruments used in this study were the Test of Attentional and Interpersonal Styles Self-Assessment (TAIS-SA) (Nideffer, 1980) for attentional styles and the Sport Competition Anxiety Test (SCAT) (Martens, 1977) for competitive traitanxiety. Batting performance was recorded by the investigator as the subjects took batting practice (from a pitching machine) during the normal course of practice. Each subject was given a log sheet and was asked to keep a record of the number of times she used the mental training program per week. This study was a pretest, posttest design, and dependent t-tests (p < .05) were calculated for the six subscales of the TAIS, the SCAT, and performance. There was a statistically significant difference from the pretest to the posttest on the levels of anxiety as measured by the SCAT and on hitting performance. While all scores on the six subscales of the TAIS-SA changed, they were not statistically significant.

Abstract (sommario):

Este trabalho tem o objetivo de descrever o atendimento de uma paciente utilizando imagens relacionadas à sua fobia no contexto clínico. É uma proposta de um enquadre diferenciado em psicoterapia psicanalítica com o fundamento na teoria de objetos e fenômenos transicionais de Winnicott, a qual se refere a uma área para a qual contribuem tanto realidade interna, subjetiva, quanto externa, objetiva, constituindo a área do brincar. A teoria freudiana sobre a angústia é revisada desde o início, em que a fobia era considerada um sintoma o qual podia aparecer em diversas afecções psíquicas. A denominação histeria de angústia foi proposta por Freud em 1909, para descrever a entidade nosológica em que a fobia é a questão central e cujo mecanismo é semelhante ao da histeria. Este trabalho foi desenvolvido a partir do método clínico com a apresentação do estudo aprofundado de um caso. A paciente, de 37 anos, buscou atendimento para aracnofobia. No psicodiagnóstico, foi aplicado o Procedimento de Desenhos-Estórias de Walter Trinca. Para a psicoterapia, realizada em 19 atendimentos, foram compostas, junto com a paciente, duas pastas, uma com fotos que lembram aranha e outra com fotos de aranhas e de teias. O caso foi compreendido como histeria de angústia, tendo ocorrido um rápido e intenso processo psicoterapêutico. Discute-se que o imagético instaurou uma linguagem onírica nas sessões, e o onírico, assim como o brincar, é campo de simbolização. As associações a partir das imagens foram eminentemente em torno da temática da aranha, sendo tais associações comparadas ao papel que as fantasias presentes no trabalho do sonho realizado pela consciência vígil têm com relação ao conteúdo latente do sonho. Discute-se que a transicionalidade propiciada pelo imagético permitiu um trabalho de figurabilidade e, ao mesmo tempo, teria permitido a constituição de um pensar por imagens, sendo as imagens associadas a palavras ao longo do processo. A paciente conseguiu uma transformação interna, uma recriação de si em que a pulsão sexual de morte (na concepção de Laplanche) foi transformada, a partir da função objetalizante (Green), em pulsão sexual de vida, com seus processos de integração, síntese e permitindo a constituição de unidades e vínculos. Pode-se considerar que houve cura, no sentido proposto por Herrmann. Conclui-se que o presente estudo de caso evidenciou a potencialidade do uso de imagens em favorecer a simbolização e as elaborações na psicoterapia psicanalítica da fobia. Novas investigações nessa área poderão responder quanto à questão das possibilidades de generalização desta experiência
This paper aims to describe the attendance of a patient by using images related to her phobia in the clinical context. It is a proposal for a differentiated framing in psychoanalytic psychotherapy based on the theory of objects and transitional phenomena by Winnicott, which refers to an area where realities, both internal subjective and external objective contribute and constitute the area of play. The Freudian theory about anguish is reviewed from the very beginning when the phobia was considered a symptom which could appear in diverse mental disorders. The term anguish hysteria was proposed by Freud in 1909 to describe the nosological entity in which the phobia is the central question and whose mechanism is similar to that of hysteria. This work was developed by using the clinical method and a presentation of a detailed case study. A 37-year-old female patient sought treatment for arachnophobia. In her psychodiagnosis, the Drawing-and-Story Procedure by Walter Trinca was applied. Her psychotherapy was conducted in 19 attendances, for which two folders were arranged with the help of the patient, one with photographs that reminded of spiders and another with pictures of real spiders and webs. The case was understood as anguish hysteria and treated in a rapid and intense psychotherapeutic process. It is discussed that the imagery established an oniric language in the sessions and the oniric context is a field of symbolization, just like the area of play. The associations made with the use of images were predominantly around the spider theme; such associations were compared to the role played by fantasies in the dreaming activity, which is carried out by the waking consciousness, in relation to the latent content of dreams. It is discussed that the transitionality provided by the imagery allowed an activity of figurability and at the same time it would have allowed a process of thinkingby images, having images associated with words all along the way. The patient achieved her inner transformation, a re-creation of herself in which her sexual pulsion of death (in Laplanche\'s conception) was transformed from an objectalizing function (Green) into a sexual pulsion of life, with its processes of integration and synthesis, enabling the constitution of units and links. It can be considered that healing did take place, as proposed by Herrmann. It is concluded that the presentcase study demonstrated the potentiality of using images to favor symbolizations and elaborations within the psychoanalytic psychotherapy of phobias. Further investigations in this area may respond to the question of possibilities towards generalizing the experience reported herein

Abstract (sommario):

Cystic Fibrosis (CF) and its treatment pose challenges to young people and their families. This research identified the psychological needs of young people with CF, assessed the feasibility of a brief treatment, and examined whether aspects could be delivered by a social robot. Thoughts young people had about their distress were an important target. The new treatment helped the young people develop a positive story of life they shared with their family, and resulted in reduced distress. Use of a social robot was feasible, and aided engagement. The research provides a foundation for further work in the area.

Abstract (sommario):

Plusieurs facteurs de risque de développement de troubles intériorisés, tels que les troubles d’anxiété et de l’humeur, ont été identifiés dans la littérature. Les deux plus importants facteurs de risques regroupent l’adversité vécue durant l’enfance (par exemple la maltraitance) et le risque parental (c’est-à-dire la présence d’un trouble intériorisé chez l’un ou les deux parents). Ces facteurs de risque ont été liés à des changements neuroanatomiques similaires à ceux observés en lien avec les troubles intériorisés. Ainsi, en présence de ces facteurs de risque, des anomalies anatomiques pourraient laisser présager l’apparition prochaine d’une symptomatologie de troubles intériorisés chez des individus encore asymptomatiques. Chez les quelques populations de jeunes investiguées, les participants présentaient des comorbidités et/ou étaient sous médication, ce qui rend difficile l’interprétation des atteintes cérébrales observées. Ce travail de thèse s’est intéressé aux liens entre ces deux facteurs de risque et les substrats neuroanatomiques associés à chacun d’eux, chez des adolescents asymptomatiques et n’étant sous aucune médication. Une première étude a examiné le lien entre le niveau de pratiques parentales coercitives et le niveau de symptômes d’anxiété, mesurés de manière longitudinale depuis la naissance, et les différences neuroanatomiques observées à l’adolescence (voir Chapitre 2). Une deuxième étude a examiné le lien entre le risque parental de développer des troubles d’anxiété et les différences neuroanatomiques observées à l’adolescence (voir Chapitre 3). Une troisième étude s’est intéressée au lien entre le risque parental de développer un trouble de dépression ou un trouble bipolaire et les différences neuroanatomiques observées à l’adolescence (voir Chapitre 4). Les résultats démontrent des différences de volume et/ou d’épaisseur corticale dans plusieurs structures clés impliquées dans le traitement et la régulation des émotions. C’est le cas du cortex préfrontal, de l’amygdale, de l’hippocampe et du striatum. Ces résultats suggèrent que certaines des différences neuroanatomiques observées dans les troubles intériorisés peuvent être présentes avant que le trouble ne se manifeste, et représenter des marqueurs neuronaux du risque de développer le trouble. Les implications théoriques et les limites de ces trois études sont finalement discutées dans le Chapitre 5.
Several risk factors for the development of internalized disorders such as anxiety, depression, and bipolar disorders have been identified in the literature. The two most important risk factors include adversity during childhood (i.e. abuse, neglect and harsh parenting) and parental risk (i.e. the presence of an internalized disorder in one or both parents). These risk factors have been linked to anatomical changes in several brain structures, which are similar to those observed in internalized disorders. Thus, in the presence of these risk factors, anatomical abnormalities may predict the appearance of internalized disorders in asymptomatic individuals. In the few studies that have investigated the influence of these risk factors in a youth population, participants often had comorbidities and/or were medicated, which makes the observed anatomical changes difficult to interpret. This work has focused on these two risk factors (i.e. adversity during childhood, in the form of harsh parenting, and the parental risk) and their link with the anatomical cerebral substrates, in asymptomatic and un-medicated adolescents. A first study examined the link between harsh parenting, levels of anxiety symptoms, as measured longitudinally from birth, and neuroanatomical differences in adolescents (see Chapter 2). A second study examined the link between parental risk of developing anxiety disorders, and neuroanatomical differences in adolescents (see Chapter 3). A third study looked at the link between parental risk for developing depressive disorder or bipolar disorder, and neuroanatomical differences in adolescents (see Chapter 4). Results show differences in volume and/or cortical thickness of several key cerebral structures involved in emotional processing and regulation. This is the case of the prefrontal cortex, orbitofrontal cortex, anterior cingulate cortex, the amygdala, hippocampus and striatum. These results suggest that some neuroanatomical differences in internalized disorders may be present before the disorder emerges, and represent neuronal markers denoting the risk of developing the disorder. The theoretical implications and limitations of these three studies are discussed in Chapter 5.

Abstract (sommario):

De nombreuses études ont démontré que les adolescents qui subissent une chirurgie correctrice de scoliose éprouvent des douleurs postopératoires intenses et cela pendant plusieurs jours après leur chirurgie. L’originalité de cette étude de type quasi-expérimental, consistait à réaliser un DVD sur une technique d’imagerie guidée et de relaxation combinée à une intervention éducative (gestion de la douleur) sur la douleur, l’anxiété, le coping et le retour aux activités d’adolescents ayant subi une chirurgie correctrice de scoliose. Prenant appui sur la théorie du portillon (Melzack & Casey, 1968) et sur la théorie transactionnelle du stress et coping (Lazarus & Folkman, 1984), quatre hypothèses ont été retenues en vue de vérifier l’effet de cette intervention. Trente et un adolescents, âgés entre 13 et 19 ans ont été répartis en deux groupes de façon aléatoire. Les participantes du groupe expérimental devaient visionner un DVD sur une technique d’imagerie guidée et de relaxation combinée à de l’information sur la gestion de la douleur en période préopératoire, au moment du congé de l’hôpital et ce, au moins trois fois par semaine sur une période d’un mois post congé. De plus, ce groupe continuait à recevoir les soins usuels. Les participants du groupe contrôle ne recevaient que les soins usuels. Les instruments de mesure utilisés furent le questionnaire concis de la douleur (QCD) (Larue F, Colleau, Brasseur, & Cleeland, 1995), l’inventaire d’anxiété situationnelle et de trait d’anxiété (IASTA-Y) (Gauthier & Bouchard, 1993) et l’inventaire du coping face à la douleur pédiatrique (Spicher, 2003). Quatre temps de mesure ont été planifiés, soit la journée avant la chirurgie, au congé de l’hôpital, au 14ième jour post congé et lors de la visite à la clinique d’orthopédie à un mois post congé. Les résultats montraient que les deux groupes étaient équivalents en ce qui concernait les caractéristiques sociodémographiques et les variables dépendantes. Les participants du groupe expérimental présentaient une douleur générale ressentie dans le dernier 24 heures plus basse au 14ième jour (p = 0,012) et un mois après leur congé de l’hôpital (p = 0,049). Certaines activités quotidiennes ont démontré une différence significative au 14ième jour soit : les activités scolaires ou de travail (p = 0,046), et les activités de soutien vital (manger, dormir) (p = 0,024), Par contre, nous n’avons pas observé de différence significative au niveau de l’anxiété situationnelle et des stratégies adaptatives de coping entre les deux groupes. L’auteur conclut que le niveau de douleur postopératoire des adolescents qui ont subi une chirurgie correctrice de scoliose peut être réduit par un visionnement d’un DVD sur une technique d’imagerie guidée et de relaxation combinée à une intervention éducative (information sur la douleur). De plus, ceci semble avoir un effet positif sur le retour plus rapide de certaines activités quotidiennes.
Several studies have shown that a spinal fusion surgery to repair scoliosis is a distressing experience for adolescents. This type of surgery involves extensive surgical lesions to soft tissues and bones that result in severe post-operative pain levels which can last several days after the surgery. Recent studies have reported significant results from interventions testing cognitive-behavioral therapies to help children and adolescents cope with acute pain experiences. The present study was designed to develop and to verify the effectiveness of a home- based guided imagery and relaxation intervention, combined to an educational intervention, presented through a DVD, on adolescent’s postoperative pain, anxiety, coping and activities of daily living following a spinal fusion. The theory of stress and coping (Lazarus and Folkman, 1984) was the conceptual framework for this randomized controlled trial study. Between April and December 2010, thirty-one adolescents 13 to 19 years of age were assigned randomly to receive either standard medical care or standard medical care with the home- based guided intervention (DVD). Participants from the experimental group were introduced to the intervention before the surgery and before discharge home. Postoperative recalls regarding the intervention were offered by telephone two weeks after the patient was discharged home. The Brief Pain Questionnaire (French version) was used to assess adolescents’ usual activities and pain. The anxiety was measured using the child/adolescent version of Spielberger’s State-Trait Anxiety Inventory (French version), and the coping strategies were measured by using the French version of the Pediatric Pain Coping Inventory. Data collection, using these questionnaires, was performed before the surgery, before discharge home, two weeks post-discharge and one month following discharge from the hospital. Results have shown that there were no differences among the groups before the surgery on gender, age, daily activities, anxiety, adaptive strategies on coping and pain. Participants of the experimental group presented a lower mean on pain intensity two weeks (p = 0,012) and one month after being discharged home (p = 0,049). Significant results were obtained in the experimental group at two weeks post-discharge regarding some of the activities of daily living: school or working activities (p = 0,046) and vital support activities (eg. eat, sleep) (p = 0,024), On the other hand, we did not observe significant differences between both groups on all other variables. Guided imagery and relaxation intervention combined to an educational intervention was superior to standard care for the treatment of postoperative pain two weeks and one month after returning home. Furthermore, this intervention seems to have a positive effect on the resuming by adolescents of some of their activities at home.

The study was aimed to investigate the effects of intervention of imagery training on taekwondo athletes’ imagery ability and anxiety. Research methods: subjects which were students of taekwondo expertise in sports class from four high schools in northern area were divided into experiment group (n=37) and control group (n=35). Experiment group had imagery intervening course for six weeks, twelve times in total, while control group had no intervention of imagery course. In addition, subjects were asked to do the pre-test and the post-test at the first and the last courses, and five random subjects were interviewed in experiment group after post-test. Sport Imagery Ability Questionnaire (SIAQ), Three-factor Anxiety Inventory (Cheng, Hardy, & Markland, 2011), self-report imagery checklist and interview outlines were used as research instruments. Quantitative data adopted SPSS20.0 to do the descriptive statistic and independent-sample t-test in order to analyze the differences between pre-test and post-test; qualitative data was transformed into sort-out key points from interview transcripts. The results showed that experiment group ‘s imagery ability (with five dimensions in total: mastery, skill, goal, affect and strategy),were elevated significantly, especially mastery imagery ability. Also, regulatory dimension of anxiety was enhanced in the three-dimension of anxiety model. Imagery training checklist showed increase in course satisfaction, and number of imagery users beside imagery course was increasing as well. The results of experiment group’s interview also pointed out imagery training course was helpful for sports performance, and subjects were willing to take such a curriculum in the future and recommend the course to others. Main conclusion: intervention of imagery training course can effectively enhance five dimensions of imagery ability and promote regulatory dimension of anxiety. These are going to have a positive effect in sports performance; therefore, we suggest that coaches and athletes should value imagery training and systematically practice it in usual sports training.

The purpose of this study was to understand which imagery intervention has effect on a swimmer's imagery ability, somatic anxiety and swimming performance. METHODS: Sixteen swimmers in the National High School Physical Education Class were enrolled in the study and randomly assigned to the experimental and control groups. Among them, the experimental group were required to receive image training for sixteen times, and the control group did not receive image training. All study participants were required to measure imagery ability, somatic anxiety, subjective and objective swimming performance before the first and after the last intervention, and to receive image training examine at the end of each intervention. The data were analyzed by single factor covariate, the difference between the experimental group and the control group in the post-test results was tested. The results show that imagery intervention can effectively improve imagery ability and subjective and objective swimming performance, and can effectively reduce the degree of somatic anxiety. It is recommended that the swimming coach can arrange the image training course in the weekday training. It can not only improve swimming performance and imagery ability of the swimmer, it can also reduce the physical anxiety of swimmers and benefit from the performance on the spot.

This study aimed to explore (1).the imagery ability and anxiety of collegiate athletes; (2).the differences in imagery ability and anxiety among collegiate athletes with different background variables; (3).the relationship among imagery ability and anxiety of collegiate athletes. Data was collected through Sport Imagery Ability Inventory, it includes (1).movement imagery ability (external, internal & kinesthetic imagery ability) which were based on Revised Version of the Vividness of Movement Imagery Questionnaire (VMIQ-2, Roberts, Callow, Hardy, Markland, & Bringer, 2008); (2).sport imagery ability (skill, strategy, goal, arousal, mastery imagery ability) which were based on Sport Imagery Ability Questionnaire (SIAQ, Williams & Cumming, 2011) (3).three-Factor Anxiety Inventory (Cheng, Hardy, & Markland, 2011). These inventories were found to be with good reliability and validity. There were 319 valid cases collecting through purposive sampling. The main results are as follows: 1. Collegiate athletes were better at internal and external movement imagery than kinesthetic imagery. 2. Collegiate athletes were at best at imagining achieving goals yet worst at imagining sports strategies. Furthermore, athletes who trained longer were better at imagining specific skills and sports strategies than less training athletes. Finally, elite athlete had better imagery abilities of skills, strategies, achieving goals, regulating emotion, and mental toughness in sport situation. 3. Collegiate athletes were good at regulating anxiety, and they had higher cognitive anxiety than physiological anxiety. Besides, elite athletes had higher regulation dimension of anxiety than less skillful athletes. 4. Collegiate athletes had better movement imagery ability when they had better sport imagery ability. 5. Internal perspective, kinesthetic, skill, strategy and mastery imagery ability could predict regulation dimension of anxiety, and arousal imagery ability could negatively predict physiological anxiety.

Abstract (sommario):

M.A.
It is well known that high levels of anxiety and/or depression often accompany the diagnosis and treatment of breast cancer. Literature from various sources, but in particular from the fairly new field of research, Psychoneuroimmunology, also provides ample evidence that excessive anxiety and/or depression can be immunosuppressive. It makes sense, therefore, that any intervention restoring balance to the immuno-regulatory system, thereby allowing the body’s innate healing processes to focus on eliminating cancer, is highly desirable. In line with current thinking based on the mind-body connection as well as cognitive behavioural techniques utilised in many therapeutic settings, various psychological interventions have been found to help the patient gain a better sense of control over distressing symptoms and side-effects of cancer. Some of these include: basic cognitive restructuring, hypnotherapy, relaxation-meditation techniques, art and music therapy, and guided imagery. Substantial international research was found illustrating the beneficial affect that the psychological intervention, guided imagery, provided in such diverse settings including work, sport and health. In this regard, it was decided to run a pilot study to ascertain whether a specifically designed tape recording with relaxing music and dialogue aimed at helping patients manage and cope with negative symptoms of cancer, could significantly reduce anxiety and/or depression levels in women with breast cancer. To operationalise the above, 40 women, aged between 30 and 60, with Stages 1, 2 or 3 breast cancer, who are about to commence adjunctive chemotherapy, were randomly selected to a treatment and a control group. A quasi-experimental design was applied to this study whereby the treatment group was subjected to pre- and post chemotherapy Hospital Anxiety & Depression (HAD) Scale and blood pressure measurements on their 1st, 3rd and final cycle of treatments. The HAD Scale is a well-researched and respected, quick, self-diagnostic assessment utilised abroad and in this country. The measurement of a person’s blood pressure is provided as a physiological backup to the psychometric assessment of the individual’s anxiety levels. For the intervention, each participant was supplied with her own copy of Healing Imagery for Cancer CD or audiotape, produced by a South African medical doctor, specialising in the “wellness” field. The participant was requested to listen to this tape as often as possible, but particularly during her chemotherapy treatments. The control group was tested pre-1st cycle of chemotherapy and post-6th cycle of chemotherapy. The main hypothesis of this pilot study was that there would be statistically significant decreases in levels of anxiety and depression as a result of the intervention of guided imagery tape recording in women with breast cancer undergoing adjuvant chemotherapy. Statistical analysis of the data revealed that the guided imagery intervention correlated with a decrease in blood pressure (systolic and diastolic) measurements, as well as depression and anxiety over a six-cycle period of chemotherapy. The most significant decrease was correlated with the anxiety variable. This pilot study revealed some methodological weaknesses but at the same time results are sufficiently encouraging to warrant further in-depth research regarding the use of guided imagery as a cost-effective, relatively easy method for individuals with cancer to learn and utilise as part of their integrative treatment regimen.

There are many factors that affect the outcome of sport competitions. With the rise in the level of sports, superb technique and good physical capability are the basic abilities of every athlete. Psychological skill is one of the key to win the game. Many of the references indicate biofeedback training and imagery training can effectively improve psychological skills. But there are only a few research are aimed at high school athletes. The main purpose of this study was to (1) understand current situation of trait anxiety and psychological skill of high school baseball players. (2) investigate the effect of imagery and biofeedback training towards trait anxiety. (3) investigate the effect of imagery and biofeedback training towards psychological skill. Using 49 Kao-Yuan high school athletes as participants. Average age is 16.91. Average length of baseball career is 5.85 years. All of them had never accepted any psychological skills training. They were divided into three groups, high anxiety, low anxiety and control group, doing six-week imagery and biofeedback training. Athletes in experimental group have 55 minutes imagery and biofeedback training once a week. This study not only uses biofeedback to monitor every athletes' physiological data, but along with two inventories, "Athletic Psychological Skills Inventory" and "Trait Anxiety Inventory" so as to analyze and compare the differences between before training and after training of athletes. The results show that: (1) trait anxiety is obviously decreased and helped in the overall trait anxiety after imagery and biofeedback training. (2)After imagery and biofeedback training, the high and low anxiety group players reach a significant level in five aspects of overall skills (stress and adversity adjustment, motivation, enlightenment, concentration and self-confidence). (3) The sixth week of training, high and low anxiety group's galvanic skin response(GSR), heart rate(HR) values were far lower than the first week. In the sixth week of control group, GSR was higher than the first week. This shows that after six weeks of training, participants were able to regulate their tension status by using biofeedback. (4) After six weeks of training of experiment group, there was no difference in the heart rate(HR), heart rate variability(HRV),respiration amplitude(RESP) and electromyography(EMG).

Lung cancer ranks 6th among the global causes of death, while ranks first in Taiwan. Surgery is the best treatment for early-stage lung cancer. 80% of patients experience moderate to severe pain within 24 hours after surgery, and 40% of patients show the anxiety symptom, leading to autonomic nervous system changes. The purpose of this study is to explore the effect of guided imagery for pain, anxiety, and heart rate variability on postoperative lung cancer patients. The quasi-experimental research design was adopted, with 60 postoperative lung cancer patients from the surgical intensive care unit of a hospital in Yilan County as research participants. Through random distribution, 30 patients each were distributed to the experimental group and the control group. Provided that patient treatment was not affected and no additional workload was imposed on the nursing personnel, flexible intervention time was adopted. For the experimental group, a 20 minute audio guided imagery was administered an hour, 3.5 hours, 16 hours, and 23.5 hours after surgery respectively; for the control group, postoperative routine nursing care was administered. An anxiety and heart rate variability pretest was carried out one day before surgery; a pain assessment pretest was carried out after admission into the intensive care unit and being conscious; an intermediate test was carried out 4 hours after surgery; and a posttest was carried out 24 hours after surgery. The Numerical Rating Scale, NRS for pain and the State Trait Anxiety Inventory, STAI-S were used for evaluating pain and anxiety; the Heart Rate Variability, HRV was used to analyze standard deviation of all normal to normal intervals, SDNN; high frequency power, HF; and low frequency power/high frequency ratio, LF/HF ratio, to evaluate the physiological changes of the autonomic nervous system. The results were using Generalized Estimating Equation, GEE for statistical analysis. The research results show that for the experimental group, the degree of pain, the degree of anxiety, and the LF/HF Ratio 4 hours after surgery were all lower compared to that of the control group; the degree of pain, the degree of anxiety, and the LF/HF Ratio 24 hours after surgery were also lower compared to that of the control group; the HF was higher than that of the control group, all reaching significant differences (p<0.001). The guided imagery is a simple and non-invasive nursing care measure that not only reduces the pain and anxiety of postoperative lung cancer patients, but also enhances the activity of the parasympathetic nerves and improves the balance between sympathetic and parasympathetic nerves. The research results shall serve as postoperative nursing care measures for alleviating pain and anxiety.

Abstract (sommario):

Hypertension occurs in nearly 10% of pregnancies, and is associated with infant and maternal morbidity and mortality. Prior studies of non-pregnant adults have demonstrated the effectiveness of a variety of relaxation therapies in reducing blood pressure. A pilot randomized controlled trial was conducted, the purposes of which were 1) to provide preliminary evidence regarding the usefulness of guided imagery (GI) in reducing blood pressure in hypertensive pregnant women, and 2) to answer feasibility questions for a larger trial. Pregnant women with hypertension prior to 37 weeks gestation (n = 69) were randomized to either 15-minute periods of guided imagery (n = 34), or of quiet rest (QR) (n = 35), twice daily for four weeks or until delivery, whichever came first. Daytime ambulatory mean arterial pressure (MAP), systolic and diastolic blood pressures, anxiety, rest and GI use were measured weekly, to a maximum of four weeks. Sixty women completed at least one week in the study; 46.4% completed four weeks. Compliance was excellent. Intention to treat analysis was used. In the unadjusted analysis, women allocated to GI had significantly lower average daytime ambulatory mean MAP elevations from baseline to their last week of study participation than women allocated to quiet rest (GI: M = 1.58 mmHg, SD = 7.63; QR: M = 5.93 mmHg, SD = 6.55; t = 2.36, p = .02). However, the effect was no longer statistically significant (p = 0.14) when adjusted for baseline mean arterial pressure and gestation. There was no statistically significant difference in the numbers of women who were prescribed antihypertensive medication after randomization (GI: n = 16, QR: n = 13, X2 = 0.74, p = .46). There was also no evidence of an effect of guided imagery on anxiety. Nearly 90% (n = 26) of the guided imagery group indicated they would use it again, either in a subsequent pregnancy or during stressful life events. Given the ease of use, low cost, acceptability to women, and lack of risk of guided imagery, an adequately-powered randomized controlled trial is warranted.

Abstract (sommario):

The purpose of this study was to examine the effects of a competition routine intervention on youth swimmers’ competition anxiety, confidence and performance. Participants of this study were youth swimmers (n = 4; female) between the ages of 12-16. Through the use of a multiple-baseline, single-subject design, participants received a competition routine intervention involving imagery, positive self-talk and a relaxation deep-breathing technique. Mixed methods were used, with participants completing the Competitive State Anxiety Inventory for Children questionnaire prior to their swim race and a reflective questionnaire following their swim race. Participants also took part in a follow-up interview upon completing the study. Participants showed no considerable decrease in cognitive and somatic anxiety, or increase in self-confidence or performance following the intervention. However, reflective questionnaire and interview results showed that participants perceived a positive improvement in all of these areas and found the intervention beneficial.

This study aimed to explore the imagery of high social anxious individuals in the social-evaluative context by manipulating self-focused attention , and also attempted to clarify the content of the imagery, the perspective formed by the context, and the influence on the anxiety emotion. The past studies on the issues of whether the negative self-imagery of high social anxious individuals spontaneously occurred in a social threat context or only occurred in the self-focused attention have not carried out any empirical research so far, and thus it is the main research purpose of this study. In this study, 37 high and 36 low social anxious individuals were selected to conduct the experiment. After being manipulated the self-focused attention according to the groups to which they had been assigned, the participants had to engage in a social evaluation task, and a further investigation would be undertaken according to their content of inner imagery obtained in the task. The research results showed that high social anxious individuals being manipulated the self-focused attention apparently had a higher proportion of negative messages in their content of imagery and also had a relatively higher change in their anxiety emotion before and after the experiment. On the contrast, no higher proportion of negative messages in the content of imagery was observed in the group of high social anxious individuals that were not being manipulated the self-focused attention and in other two groups of low social anxious individuals. Similarly, there were no significant differences in the forms presented and the anxiety emotion in those groups as well. The inner imagery of high social anxious individuals would be influenced by the present status of the focus of attention. While in a higher self-focused attention, the content of imagery tends to be more negative, and tends to be observer perspective.
