Résumé :

- The present study analyses the relation among media influence, self esteem and body dissatisfaction in a group of preadolescent boys and girls. 243 preadolescents with the mean age of 12 were involved. The group consisted of 127 boys and 116 girls. They were asked to complete the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3; Thompson et al., 2004), the Body Shape Questionnaire (Dowson e Henderson, 2001) and the Rosenberg Self-Esteem Scale (Rosenberg, 1965). Preadolescent females reported higher levels of body dissatisfaction than preadolescent males. They also scored higher in three SATAQ-3 subscales: whether media are important source of information about being attractive, internalization of a media thin ideal and perceived media pressures to be thin. Body mass index and internalization of a thin ideal emerged as significant predictors of body dissatisfaction for both sexes. Perceived media pressures predict body dissatisfaction only among girls.Key words: media influence, self-esteem, body dissatisfaction, preadolescenceParole chiave: influenza dei media, autostima, insoddisfazione corporea, preadolescenza.

Résumé :

Abstract. Body dissatisfaction has been extensively studied in populations of all ages, however, no revisions to provide information about what has been found, inconsistencies, limitations and possible direction future research should take in children and preadolescents. Therefore, the aim of this paper was to conduct a systematic review of body dissatisfaction in children and preadolescents. To fulfill this purpose, we conducted a search in the databases of MEDLINE, Science Direct and Scopus, with the following keywords: body dissatisfaction, body perception, self-evaluation, body concept, preadolescents, and preteen children in different combinations, according to the inclusion and exclusion criteria were analyzed 63 articles. In the studies reviewed there is no consensus about the approach of body dissatisfaction, are permeated by methodological problems, mainly in the way that is evaluated in childhood because of the difficulty of children to understand the assessment tools, giving result in inconsistent results, further research is less in preadolescence where accurate estimation of body dissatisfaction. That is why it is considered to extend the research in children, with the inclusion of development that would create assessment methods according to age. Key words: Body dissatisfaction, body image, children, preadolescents. Resumen. La insatisfacción corporal ha sido ampliamente estudiada en poblaciones de todas las edades, sin embargo, no hay revisiones que proporcionen información acerca de lo que se ha encontrado, las inconsistencias, limitaciones y la posible dirección que deben tomar futuras investigaciones en niños y preadolescentes. Por lo cual, el objetivo de este artículo fue realizar una revisión sistemática de la insatisfacción corporal en niños y preadolescentes. Para cumplir este propósito, se realizó una búsqueda de artículos en las bases de datos de MEDLINE, Science Direct y Scopus, con las siguientes palabras clave: body dissatisfaction, body perception, self- evaluation, body concept, preadolescents, preteen y children en diferentes combinaciones, de acuerdo con los criterios de inclusión y exclusión se analizaron 63 artículos. En los estudios analizados no hay un consenso acerca del abordaje de la insatisfacción corporal, se encuentran permeados por problemas metodológicos, fundamentalmente en la forma en la que se evalúa en la infancia debido a la dificultad de los niños para comprender las herramientas de evaluación, dando como resultado resultados inconsistentes, adicionalmente hay menos investigación que en la preadolescencia donde es precisa la estimación de la insatisfacción corporal. Es por ello que se considera extender la investigación en población infantil, con la inclusión del desarrollo que permitiría crear métodos de evaluación de acuerdo a la edad. Palabras clave: Insatisfacción corporal, imagen corporal, niños, preadolescentes.

Résumé :

The article describes the experimental study of volitional qualities: perseverance and firmness in preadolescence. In our research were included 239 preadolescents. Perseverance and firmness were examined by applying Technique for the study of volitional qualities of personality (by Н. Стамбулова). The study results shoes that a few of preadolescents have a high level of perseverance and firmness under the expression of the expressivity and generalization factors. Boys are characterized by a higher level of development of perseverance and firmness under expression of expressivity factor, meanwhile at girls we identify a higher level of development of perseverance and firmness under expression of generalization factor. The high level of perseverance and firmness under expression of expressivity factor prevails at 13 years old preadolescents, while the same qualities, under expression of the generalization factor is more developed at 14–15 years old preadolescent.

Résumé :

The purpose of this study was to examine the effect of a single bout of exercise on neurocognitive function in preadolescent children and young adults by determining the modulatory role of age and the neuroelectrical mechanism(s) underlying the association between acute exercise and executive function. Twenty preadolescents and 20 young adults completed the Stroop test, and neuroelectrical activity was recorded during two treatment sessions performed in a counterbalanced order. Exercise treatments involved moderate intensity aerobic exercise for 20 min as the main exercise and two 5 min periods of warm-up and cool-down. The control treatment participants read for a similar duration of time. Acute exercise improved participant reaction times on the Stroop test, regardless of Stroop congruency, and greater beneficial effects were observed in young adults compared to those in preadolescents. The P3 amplitudes increased after acute exercise in preadolescents and young adults, but acute exercise induced lower conflict sustained potential (conflict SP) amplitudes in preadolescent children. Based on these findings, age influences the beneficial effect of acute exercise on cognitive performance in general. Furthermore, the event-related brain potential differences attributed to acute exercise provide a potential clue to the mechanisms that differentiate the effects of acute exercise on individuals from preadolescence to young adulthood.

Résumé :

Growing up in a high family risk (HFR) environment is accompanied by difficulties in executive functions (EFs) and interpersonal skills (IS) that may persist into adulthood. Because preadolescence is a critical period, this study will assess a multicomponent mediational intervention program, to determine the possibility of improving these skills. There were 61 preadolescent participants, between the ages of 8 and 12; 34 were associated with HFR and 27 were associated with low family risk (LFR). All the participants were tested with EF and IS measures. Results showed that, prior to treatment, the HFR preadolescents had poorer performance on EF and IS than did the LFR preadolescents. In the posttreatment measures, to assess the utility of the multicomponent program, the HFR preadolescents group was able to match the scores of those in the LFR group. In addition, intervention effects in the HFR group were maintained in the follow-up assessment.

Résumé :

The purpose of this study is to capture a snapshot of the lives of Brazilian preadolescents and gain a deeper understanding of the variables that influence compliance with parental rules. This analysis draws from the São Paulo Legal Socialization Study, a cohort study (<em>N</em> = 800; age = 11 years) from public and private schools. Descriptive statistics provide a perspective on normative Brazilian parenting practices and preadolescents’ perceptions of parental legitimacy across multiple domains. Hierarchical linear modeling revealed that procedural justice, global legitimacy, issue-specific legitimacy, and disciplinary techniques all significantly predicted compliance across issues and between preadolescents. Parents who used constructive disciplinary practices paired with procedural justice practices were more likely to be perceived as legitimate authorities and to have their preadolescent children comply with their rules. Our findings broaden the literature on constructive parenting practices in preadolescence, and allow for greater generalizability of current Western research to a diverse metropolitan setting in Brazil.

Résumé :

Preadolescence is one of the most difficult stages of human development. This is marked by major and profound changes that affect the psycho-emotional development of the preadolescent. The most frequent changes are felt in: the physiological aspect, the relationships it establishes with peers and/or adults, the level of development of cognitive processes, the level of intelligence, intelligence, skills and social skills and in the affective aspect. Preadolescence is characterized by strong emotions, a fact that manifests itself in high excitability, mood variability, anxiety, aggression and other violent reactions. Since the experience of preadolescents is limited, they tend to assert themselves, to demonstrate their independence. In the circle of her colleagues, they often try to assert themselves, proving that they are people with great life experience. Such a statement is often associated with imitation of antisocial behaviors.

Résumé :

Because the preadolescent's inner world is still undeveloped and insufficiently enriched by the experience of experiencing critical situations that stand in the way of meeting important needs, his activism, aimed at overcoming them, is not stimulated. Therefore, in difficult situations the preadolescent includes the defense mechanisms. When the mechanisms prove to be inefficient, the body instinctively looks for a way out and often finds it in the external environment. Psychoactive substances can be used as external procedures to defend against the psychotraumatic situation and the vulnerability of preadolescents to drug use is directly related to the fact that drugs have become accessible, the consumption being often associated with the pressure exerted by the group of friends.

Résumé :

This study focuses on the relationship between preadolescents and youtubers, with the objective of observing how tweens integrate youtubers as referents of a teen digital culture. From a socio-psychological and communicological perspective, a mixed methodological design was applied to carry out the audience study, which was divided into two parts: a quantitative analysis of the audience via a survey administered to 1,406 eleven-twelve year old students of Catalan Secondary Schools, and a qualitative analysis of the preadolescence audience using three focus groups. The quantitative data was analysed with SPSS and the qualitative data with the help of the Atlas.ti software. The results demonstrate that tweens consider youtubers as referents for entertainment and for closeness to a teen digital culture, but not really as a role models or bearers of values as influencers. Also, preadolescents show some dimensions of Media Literacy, since they recognise youtubers’ commercial strategies and their role as actors and professionals. The study notes gender bias in some aspects, and is an introduction to observation of the social functions of youtubers amongst teenagers, individuals who are in the process of constructing their identity and on the point of becoming young adults. El presente estudio se centra en la relación entre preadolescentes y youtubers, con el objetivo de observar cómo los primeros integran a los youtubers como referentes de una cultura digital juvenil. Desde una perspectiva sociopsicológica y comunicativa, se aplicó un diseño metodológico mixto para llevar a cabo el estudio de audiencia, organizado en dos partes: un análisis cuantitativo de la audiencia a través de un cuestionario administrado a 1.406 estudiantes de once-doce años de institutos en Cataluña, y un análisis cualitativo de la audiencia preadolescente a partir de tres «focus group». Los datos cuantitativos se analizaron con SPSS y los cualitativos con la ayuda del programa Atlas.ti. Los resultados demuestran que los preadolescentes consideran a los youtubers como referentes para el entretenimiento y por su proximidad a una cultura digital juvenil, pero no realmente como modelos o portadores de valores en tanto que «influencers». Además, los preadolescentes muestran alguna dimensión de Alfabetización Mediática, al identificar las estrategias comerciales de los youtubers y sus roles profesionales. El estudio da cuenta de un sesgo de género en algunos aspectos, y resulta una introducción a la observación sobre las funciones sociales de los youtubers entre los adolescentes, personas que están en pleno proceso de construcción de sus identidades y a punto de convertirse en jóvenes adultos.

Résumé :

Abstract Objectives Parents play an important role in keeping their children safe. However, this becomes more difficult during preadolescence as children seek greater autonomy away from the direct supervision of adults. The current study focused on preadolescent youth (10–13 years) and examined parent–child disagreements about safety, with a focus on determining if child temperament attributes moderate the relation between how parents learn of these and resolve these disagreements. Methods A short-term longitudinal design was used. Parents and children retrospectively recalled safety disagreements together and then independently completed questionnaires about these. Parents then tracked disagreements over 1 month. Results The behavioral attributes of inhibitory control and risk-taking propensity both moderated the relationships between parental source of knowledge of safety disagreements and subsequent methods of resolution. Conclusion Safety-promotion messaging for parents of preadolescents may need to be tailored based on child attributes to maximize effectiveness.

Résumé :

Background: This study aimed to examine whether sedentary digital media use in preadolescence increases the risk of being overweight 3 years later, and whether this association differs based on preadolescents’ leisure-time physical activity (LTPA) levels. Methods: The authors conducted a 3-year follow-up study among 4661 participants with a mean (SD) age of 11 (1) years at baseline and 14 (1) years at follow-up. A web-based questionnaire assessed sedentary digital media use and LTPA. The authors categorized baseline LTPA duration into 3 levels: 0 to 5 (low), 6 to 8 (moderate), and ≥9 (high) hours per week. In addition, the authors categorized adolescents as normal weight or overweight/obese at follow-up. Results: Greater amounts of sedentary digital media use at baseline associated with an increased risk of being overweight 3 years later even after adjusting for confounders. This only held for preadolescents with low baseline LTPA (OR = 1.14; 95% confidence interval, 1.05–1.24), but not among those with moderate (OR = 1.02; 0.91–1.15) or high (OR = 0.96; 0.85–1.08) LTPA. Conclusions: Preadolescent LTPA modified the long-term association between sedentary digital media use and being overweight; specifically, 6 hours per week or more of LTPA mitigated the increased risk of being overweight associated with higher amounts of digital media use.

Résumé :

Background Maternal obesity and physical inactivity have been identified as correlates of overweight and obesity and physical inactivity in older preadolescents; however, no study has explored this relationship in Hispanic preadolescents. Furthermore, the relation between maternal physical activity (PA) and blood pressure (BP) in Hispanic preadolescents has not been examined. Purpose This study aimed to assess the associations between Hispanic mothers’ PA and body mass index (BMI) and their preadolescents’ PA, screen time, BP, and BMI. Methods Data of 118 mother-child (aged 2–10 years) dyads enrolled in a cross-sectional study of metabolic syndrome in Hispanic preadolescents at a community health center in Johnson City, TN were used. Parent and child questionnaires were used to ascertain mothers’ BMI and PA and preadolescents’ PA and screen time. Preadolescents’ height, weight, and BP were measured. Multiple logistic regression was used to examine the association between child and maternal variables, adjusting for mother’s education and the child’s sex and age. Results Pradolescents of obese mothers were more likely than preadolescents of mothers with normal weight to engage in less than three days of at least 60 min of vigorous PA per week (OR: 6.47, 95% CI [1.61–26.0]). Preadolescents whose mothers did not engage in moderate PA were more likely to engage in less than three days of at least 60 min of vigorous PA per week (OR: 2.92, CI [1.18–7.24]); and have elevated BP (OR: 2.50, 95% CI [1.02–4.53]) than preadolescents whose mothers engaged in moderate PA. Discussion Our results show a negative relationship between maternal obesity and preadolescent PA, and a positive relationship between lower maternal PA and elevated BP and lower PA in Hispanic preadolescents. This suggests that interventions aimed at improving Hispanic preadolescents’ PA and BP may use maternal PA and maternal BMI (for preadolescent PA) as a modification strategy to improve health in Hispanic preadolescents.

Résumé :

Whether preadolescents perceive their parents’ authority as legitimate or not depends, in part, on the concerns and issues that they have dealt with before and during their preadolescence. Utilizing data from the first and second waves of the São Paulo Legal Socialization Study (SPLSS), we conducted one-way MANOVAs to analyze the role of procedural justice and the impact of victimization on preadolescents’ perceptions of parental legitimacy across domains. Preadolescents were split into four distinct groups based on their perceptions of parental legitimacy and whether the perception shifted across the two waves of data. The study revealed a significant difference across groups in terms of procedural justice and on preadolescents’ reported victimization levels. The latter indicate that suffering some form of victimization may have resulted in delegitimizing parental authority. The findings broaden the literature on parenting practices in preadolescence and make salient an emerging field of victimization impacting parental legitimacy.

Purpose In this study, the authors compared coarticulation and lingual kinematics in preadolescents and adults in order to establish whether preadolescents had a greater degree of random variability in tongue posture and whether their patterns of lingual coarticulation differed from those of adults. Method High-speed ultrasound tongue contour data synchronized with the acoustic signal were recorded from 15 children (ages 10–12 years) and 15 adults. Tongue shape contours were analyzed at 9 normalized time points during the fricative phase of schwa-fricative-/a/ and schwa-fricative-/i/ sequences with the consonants /s/ and /ʃ/. Results There was no significant age-related difference in random variability. Where a significant vowel effect occurred, the amount of coarticulation was similar in the 2 groups. However, the onset of the coarticulatory effect on preadolescent /ʃ/ was significantly later than on preadolescent /s/, and also later than on adult /s/ and /ʃ/. Conclusions Preadolescents have adult-like precision of tongue control and adult-like anticipatory lingual coarticulation with respect to spatial characteristics of tongue posture. However, there remains some immaturity in the motor programming of certain complex tongue movements.

Résumé :

Preadolescence is a critical period, characterised by changes in physical, hormonal, cognitive, behavioural, and emotional development, as well as by changes in social and school relationships. These changes are accompanied by the transition from elementary school to middle school. The literature shows that this transition is one of the most stressful events for preadolescents, which can have a negative impact on their well-being. The main objectives of this review, focused on the school context, were to identify protective and risk factors influencing the well-being of preadolescent students and to describe the interventions implemented. A systematic search of peer-reviewed papers published between 2011 and 2021 was conducted following the PRISMA reporting guidelines. A total of 36 full-text articles met the inclusion criteria. Studies converge in identifying risk factors that may affect student well-being in this age group: individual factors (levels of emotional awareness and self-esteem) and relational factors (friendship, teachers’ and parents’ supporting actions and roles). Intervention programs are mainly focused on improving emotional and social regulation skills that also influence academic achievement. Our findings have important implications for both research and intervention in school settings.

Résumé :

The use of ergogenic aids is common in sport, even among preadolescent athletes (8,15,25). The aim of this study was to investigate the relationship between preadolescents’ use of nutritional ergogenic aids (creatine and amino acids) and gender, age, athletic participation, and sport-relevant psychological factors (i.e., sport success motivation, task and ego orientation, self-efficacy). Two thousand four hundred fifty 11- to 13-year-old children participated in this study. Results suggest that substance use increases with age, especially among male preadolescents; that gender differences are particularly marked among older preadolescents; and that a high commitment to sport training represents a risk factor of ergogenic supplementation only when it is linked to certain psychological dispositions, such as a high ego orientation and a low task orientation.

In order to study initiative and independence we applied Technique for the study of volitional qualities of personality (by Н. Стамбулова). As results we established that the most of preadolescents (76,57%, 60,67%) have a medium level of initiative and independence under the expression of the expressivity and generalization factors. Also, we underline that boys and girls does not differ in ways of initiative and independence manifestation. At the same time during the preadolescence we observe change in initiative and independence.

Résumé :

Resourcefulness is a set of cognitive-behavioral self-control skills for coping with stress to maintain quality of life. However, research examining precursors in the development of resourcefulness in preadolescents is scant. A cross-sectional approach was used to investigate hypothesized predicting effects of intrinsic contextual factors (children’s age, gender, and school performance), extrinsic contextual factors (parents’ age, gender, education, income, and resourcefulness), and process regulators (academic stress and dispositional optimism) in a convenience sample of 361 preadolescent–parent dyads. Results show that preadolescents’ process regulators, academic stress, and dispositional optimism were significant predictors of resourcefulness. The findings suggest that preadolescents’ resourcefulness was greatly influenced by process regulators, which are cognitive perceptions intervening the use of resourcefulness. Further research with various study designs is needed to examine additional factors that may influence resourcefulness in large and more diverse child–parent samples.

Résumé :

Purpose: This study sought to determine whether healthy, overweight, and obese preadolescents living in low-income neighborhoods differ in regards to body image and weight control behaviors. It is critical to identify early precursors to body image issues so that optimal prevention programs can be implemented. Subjects: The sample consisted of 64 preadolescents ages 8 to13 years, including 29 male (45%) and 35 female (55%) fourth, fifth, and sixth graders living in low-income neighborhoods in Fresno, California. Measures: (a) Height and weight were measured to calculate BMI-for-age (kg/m2 ), and (b) the CDC 13- question Body Image Survey was administered. Analysis: ANOVA was used to compare differences in body image and weight control behaviors by weight category (healthy, overweight, obese).Results: The obese group reported more body image dissatisfaction than did the healthy and overweight groups. Obese preadolescents were less happy with their body image and dieted more than healthy weight preadolescents. Overweight preadolescents were more similar in behaviors to healthy weight preadolescents than obese preadolescents. Conclusions: Low self-esteem related to weight may be exacerbated in the adolescent years when new pressures and challenges emerge. Targeting preadolescent overweight and obese individuals with body image issues may be useful in ameliorating some of the problems that are magnified in adolescence, such as dieting and eating disorders.

Résumé :

The present three-wave panel study ( N = 973, [Formula: see text] = 11.14) sought to advance the current literature on media internalization in preadolescence by examining triggers and consequences related to preadolescents’ media internalization and use of media for appearance information. We sought to examine whether (a) media internalization and use of media for appearance information could be explained by pubertal timing and peer appearance criticism, and (b) such media internalization and use of media for information could foster dysfunctional body image investment. Structural equation analyses showed that early maturation relative to peers and peer appearance criticism predicted preadolescents’ use of media for appearance information and media internalization, 6 months later. Such media use, in turn, predicted preadolescents’ development of dysfunctional appearance beliefs, 6 months later. These results highlight the importance for future studies to examine whether preadolescents’ reliance on appearance media stems from their need to cope with current body concerns.

Résumé :

In questo articolo l'autrice s'interroga sul lavoro dello psicoterapeuta psicoanalitico della famiglia, quando č chiamato dal giudice a svolgere una consulenza tecnica nelle separazioni giudiziali. Le sedute non si limitano alla registrazione puntuale dei fatti (quale testimonianza), ma diventano un ascolto teso alla ricerca e alla comprensione del significato relazionale degli stessi, nella prospettiva di una mentalizzazione conoscitiva e al tempo stesso trasformativa, obiettivo richiesto dal quesito del Giudice. Viene evidenziato come l'intervento possa aiutare i figli a manifestare i propri bisogni emotivi e i genitori a leggerli. Se il lavoro si svolge sia a livello conoscitivo, sia a livello fantasmatico - anche attraverso i test carta e matita e la tecnica del "disegno congiunto della famiglia" - esso puň attivare nei protagonisti la "capacitŕ di sorprendersi" (Winnicott, 1968; Schacht, 2001; Bolognini, 2001). Le vignette cliniche dell'autrice cercano di mostrare come siano possibili aperture di senso e movimenti verso la consapevolezza delle emozioni in famiglie con figli bambini, preadolescenti, adolescenti.

Résumé :

Measurement of mental rotation presents a serious challenge to cognitive researchers owing to the lack of a single comprehensive measure that can be applied across the developing age groups. Objective of the present study was to develop and validate a new measure of mental rotation for preadolescent and adolescent age groups. Items were conceptualized and constructed based on existing theories. Study I checked the suitability of these items among preadolescent and adolescent age groups. After revisions, Study II was done to evaluate the item properties using item response theory. Subsequently done Confirmatory Factor Analysis provided evidence for the construct validity of the new measure. Finally, Study III was done to develop the age wise and gender wise norms for preadolescent and adolescent age groups. The newly developed measure was found to have sufficient reliability and validity and hence can be widely applied for measuring mental rotation of preadolescents and adolescents.

Résumé :

The article elucidates the problem of the relationship between the level of psychological resilience and self-esteem in preadolescents. It is argued that the high and medium levels of psychological resilience will correlate with the high level of self-esteem, and the low level of psychological resilience will correlate with the low level of self-esteem. Preadolescence is a difficult age, with many risks, physical, physiological, and mental changes, internal and external conflicts. The successful crossing of this stage depends on the level of psychological resilience it manifests. One of the determining factors for a high personal psychological resilience of preadolescents is their positive self-attitude, stable adequate self-esteem, on which self-confidence is based, an optimistic outlook on future prospects and desires. It must be borne in mind that self-esteem exists in the absence of self-humiliation and, together with the latter, acts as a protective function in preadolescents.

Résumé :

The aim of the present work was two-fold. Firstly, to evaluate the association between the consumption of ultra-processed beverages (UPB) on preadolescents’ likelihood of being obese. Secondly, to investigate the potential impact of family and school environmental stressors on this unhealthy lifestyle habit. A cross-sectional study was conducted among 1718 Greek preadolescents and their parents, during the school years 2014 to 2016. Parental and child characteristics were collected anonymously, through self-administered and validated questionnaires. Among others, UPB consumption (soft and flavored drinks) was recorded, classifying children as low, moderate, or high consumers, while anthropometric characteristics [height, body weight, Body Mass Index (BMI)] were also recorded. Almost seven out of ten preadolescents were classified as at least moderate UPB consumers, while approximately three out of ten were classified as high UPB consumers. Higher UPB consumption was associated with significantly higher levels of BMI, while preadolescents living in a more stressful family and school environment were found to consume significantly higher amounts of UPB. Stakeholders should implement programs that raise awareness among parents and teachers about the sources of stress in preadolescence as a potential “triggering factor” of unhealthy dietary preferences.

Résumé :

Confusion exists with regard to the substantive difference between self-concept and self-esteem. In an endeavour to cast some light on this confusion two studies were conducted with 1193 preadolescents using modified versions of two commonly used instruments designed to measure self-concept and self-esteem. Exploratory factor analysis indicated that both these instruments measure specific facets of the same construct, namely self-concept. General or global self-concept proved to be a difficult construct to measure in preadolescent students.

This paper compares the tendency to express autonomy in 20 Estonian, 20 Swedish, and 20 Swedish Estonian middle-class families with preadolescent children during videotaped family mealtimes. The results indicate that compared to the Swedish participants, participants from both Estonian samples expressed autonomy less frequently. Being talkative does not always mean expressing more autonomy. The Swedish preadolescents who were the most talkative and whose mothers were talking less, were more likely to express their personal needs, opinions and preferences. Possible reasons of cultural variability in autonomy orientation are discussed.

Résumé :

Purpose. Children with ADHD have known behaviors of hyperactivity and impulsivity which may result in adverse outcomes. The purpose of this study is to examine the association of serious adverse outcomes (emergency department visits within the previous year) in preadolescents and adolescents with ADHD as compared with preadolescents and adolescents without ADHD. Method. The researchers conducted a cross-sectional, secondary data analysis of National Health Interview Survey (NHIS) 2017 data concerning 2,965 children (>11 to 17 years). The NHIS data resulted from face-to-face interviews of a household member selected from a multistage area probability design representing households in the US. Data analyses for this study included Chi-square bivariate analyses and logistic regression analyses. Results. There were 13.2% of children in the sample who had ADHD. Children with ADHD were more likely to be male and non-Hispanic white. They were also more likely to have one or more additional disease or condition excluding ADHD. In adjusted logistic regression analysis on emergency department utilization by ADHD status, the adjusted odds ratio was 1.93 (95%CI: 1.35, 2.74; p = 0.0003) for preadolescents and adolescents with ADHD as compared with preadolescents and adolescents without ADHD. Conclusion. Children with ADHD were more likely to have emergency department utilization than children without ADHD. Preventive medical visits were similar between preadolescent and adolescent children with and without ADHD. Characteristics associated with ADHD may explain the increased need for emergent care. Developing interventions for children with ADHD may decrease emergency department utilization.

Résumé :

In preadolescence, research has shown links between the quality of children’s attachment relationships and children’s perceived self-regulatory abilities. However, less research has focused on the association between attachment and preadolescents’ self-regulation performance. In a sample of 120 children, aged 9–13, we administered questionnaires to assess trust in maternal support and anxious and avoidant attachment. In addition, mothers reported about their children’s self-regulatory abilities, and children performed the Stop-Signal Task (SST). Consistent with predictions, correlation analyses revealed that a more insecure attachment relationship with mother was not only associated with less self-regulatory abilities as perceived by mother but also with preadolescents’ lower self-regulation performance in the SST. Adding demographic variables as covariates to the analyses did not significantly alter these effects. The current multi-method study contributes to an increasing awareness of the importance of the quality of the mother–child relationship for children’s self-regulation.

Résumé :

Background Athlete’s heart is a term used to describe the morphological and functional changes in the hearts of athletes. Recent studies suggest that these changes may occur even in preadolescent athletes. This study aims to improve our understanding of the changes occurring in the preadolescent athlete’s heart. Design and methods Cardiac morphology and function in 76 preadolescent cross-country skiers (aged 12.1 ± 0.2 years) were compared with 25 age-matched non-competing preadolescents. Echocardiography was performed in all subjects, including 2D speckle-tracking strain echocardiography and 3D echocardiography. All participants underwent cardiopulmonary exercise testing to assess oxygen uptake and exercise capacity. Results Athletes had greater indexed VO2 max (62 ± 7 vs. 44 ± 5 mL/kg per min, p < 0.001), indexed left ventricular end-diastolic volume (79 ± 7 vs. 68 ± 7 mL/m2, p < 0.001), left ventricular mass (69 ± 12 vs. 57 ± 13 g/m2, p < 0.001), indexed right ventricular basal diameter (28.3 ± 3.0 vs. 25.4 ± 3.5 mm/m2, p < 0.001) and right atrial area (10.6 ± 1.4 vs. 9.7 ± 1.2 cm2/m2, p < 0.01). There was no difference in left ventricular ejection fraction, global longitudinal strain, and global circumferential strain and right ventricular fractional area change between the groups. Controls had higher right ventricular global longitudinal strain (−28.1 ± 3.5 vs. −31.1 ± 3.3%, p < 0.01). VO2 max was highly correlated to left ventricular end-diastolic volume ( r = 0.76, p < 0.001). Conclusion Athletes had greater left ventricular mass and greater left and right ventricular chamber dimensions compared with controls, while left ventricular function did not differ. Interestingly, right ventricular deformation was significantly lower compared with controls. This supports the notion that there is physiological, adaptive remodelling in preadolescent athlete’s heart.

Résumé :

Attention deficit disorder with hyperactivity (ADHD) is a common comorbidity in children with Tourette syndrome (TS). However, motor restlessness and high levels of sensorimotor activation or “overactivity” may be a feature of TS rather than a distinct ADHD comorbidity. The link between overactivity and ADHD in TS has yet to be established and in particular between adult and preadolescent manifestations. The current study furthers this understanding of ADHD features in TS by investigating the relationship between cognitive and behavioral aspects of ADHD and TS. The style of planning (STOP) overactivity scale was compared in preadolescent (n=17) and adult (n=17) samples. The STOP overactivity scale measures the characteristic overactive style of planning in everyday life. The aims of the study were twofold as follows: (1) to see if an overactive style was present in adolescents as well as in adults, and (2) to see if this overactive style correlated with hyperactivity, impulsivity, or perfectionism. Results suggest that overactivity may be a better description of the hyperactivity manifestations in TS. Behavioral components of overactivity were present in preadolescents while the cognitive components were more frequent in adults. Overactivity relates at the same time to perfectionism and impulsivity.

Esta investigación forma parte de los estudios sobre Abuelidad, que adelanta el Grupo de Investigación sobre Desarrollo de la Universidad del Quindío. Se describe, desde la percepción de preadolescentes de la ciudad de Armenia, la figura del abuelo favorito a partir de características del abuelo (edad, sexo, familia de origen, ocupación, ubicación geográfica y frecuencia de contacto) y como ésta varía en función de las características del nieto. La muestra estuvo conformada por 600 preadolescentes de distintas instituciones educativas a los cuales se les aplicó un instrumento sobre la relación abuelo-nieto. Los datos fueron procesados en Stadistical Product and Service Solutions (SPSS), se utilizó estadística descriptiva, en la identificación de la figura del abuelo favorito y para establecer diferencias significativas en función las características del nieto, el Chi-cuadrado y la prueba U de Mann Whitney. Los resultados indican que los nietos eligen como abuelo favorito en mayor porcentaje a abuelas (81.4%), de línea materna (62.1%), entre 60 y 70 años (43.8%), jubilados o amas de casa (72.8%), viven en la misma ciudad que sus nietos (32.7%), les ven casi todos los días (47.4%). Se encontró que las características de la figura del abuelo presenta variaciones en función de características del preadolescente. Así, la edad del abuelo favorito varía de acuerdo con la estructura familiar y el orden de nacimiento del nieto, cuando la madre trabaja, los nietos prefieren en mayor proporción a las abuelas maternas; la distancia geográfica y la frecuencia de contacto entre abuelos favoritos y nietos varían en función de la estructura familiar, el número de hermanos y el orden de nacimiento del preadolescente

Résumé :

Parental practices such as inconsistent discipline, psychological control, and imposition have been linked to the development of internalizing and externalizing problem behaviors in preadolescents. This study aimed to identify the association these practices had on Mexican preadolescent problem behaviors through Structural Equation Modeling. The sample consisted of 306 elementary students from three public schools in Mexico City (age M = 10, SD = 0.92). Students completed subscales from the Parental Practice Scale, the Alabama Parenting Questionnaire, and the Strengths and Difficulties Questionnaire. Paternal imposition and maternal psychological control were significant predictors for internalizing problems, while inconsistent discipline was a significant predictor of externalizing problems. The results highlight that although parental practicevalues might differ across cultures, their association to problem behaviors are similar.

Résumé :

Background: Cardiometabolic disease (CMD) risk often begins early in life. Healthy lifestyle behaviors can mitigate risk, but the optimal combination of behaviors has not been determined. This cross-sectional study simultaneously examined the associations between lifestyle factors (fitness, activity behaviors, and dietary patterns) and CMD risk in preadolescent children. Methods: 1480 New Zealand children aged 8–10 years were recruited. Participants included 316 preadolescents (50% female, age: 9.5 ± 1.1 years, BMI: 17.9 ± 3.3 kg/m2). Fitness (cardiorespiratory fitness [CRF], muscular fitness), activity behaviors (physical activity, sedentary, sleep), and dietary patterns were measured. Factor analysis was used to derive a CMD risk score from 13 variables (adiposity, peripheral and central hemodynamics, glycemic control, and blood lipids). Results: Only CRF (β = −0.45, p < 0.001) and sedentary time (β = 0.12, p = 0.019) were associated with the CMD risk score in the adjusted multivariable analysis. CRF was found to be nonlinear (VO2 max ≤ ≈42 mL/kg/min associated with higher CMD risk score), and thus a CRF polynomial term was added, which was also associated (β = 0.19, p < 0.001) with the CMD risk score. Significant associations were not found with sleep or dietary variables. Conclusion: The findings indicate that increasing CRF and decreasing sedentary behavior may be important public health targets in preadolescent children.
