Abstract:

Research has consistently shown schizophrenics to perform significantly poorer than normal controls on commonly used measures of neuropsychological functioning. Research on the neuropsychological functioning of first-degree relatives of schizophrenics who do not themselves have schizophrenia is comparatively sparse but suggests the likelihood of deficits in this group as well. A battery of standard neuropsychological tests was administered to three groups: first-degree relatives of schizophrenics who do not themselves have schizophrenia (FDR-SCZ), first-degree relatives of persons with major depression and bipolar disorder (FDR-MOOD), and normal controls (NC). The FDRSCZ group was not found to demonstrate significantly impaired performance relative to the other two groups on any of the hypothesized or exploratory analyses. These implications of these findings are discussed with reference to previous studies and future research.

Abstract:

I examined the effects of a residential treatment program on symptoms and mental health service use in 14 chronic schizophrenics. The clients chosen for this study were the most difficult clients in this population due to continued high service usage (i.e., time spent in locked facilities). All 14 clients had been in a locked facility at least 1 year immediately prior to treatment. The program included skills training, reinforcement for incompatible behavior, and a token economy. The clients' symptomology was recorded twice a day. My hypotheses were that symptoms would decrease due to the program, and clients mental health service use would also decrease in a 1 year follow-up. Mental health service use (time spent in a locked facility) did decrease dramatically after treatment. All 14 clients had a decrease in the amount of time spent in locked facilities after treatment. The total cost for these clients in locked facilities the year immediately prior to treatment was conservatively estimated at $776,500. The annualized figure of the total cost of these 14 clients after treatment was estimated at $44,775, saving San Joaquin County approximately $721,725 in 1 year. The results did not support the hypothesis that the program reliably decreases schizophrenic symptomology as we measured it.

Abstract:

This work addresses some of the difficulties encountered while working in psychotherapy with a residual schizophrenic. While there is an abundance of literature on psychotherapy for schizophrenia, both supporting and also refuting its merit, what the literature fails to reveal is that there appears to be a class of schizophrenic who, while apsychotic and able to communicate in the everyday sense of the word, is in a psychic space which speaks of a break with the basic relational elements of the human order. The quality of the patient's psychic life is such that almost nothing of what the literature describes as useful and appropriate in working with schizophrenics seems to help in the psychotherapeutic work with this type of patient. This study describes these issues with relevance to a particular residual schizophrenic. The Illustrative-didactic case-study method was used to discuss the four-and- a-half month psychotherapy with this patient. The patient's early developmental history, premorbid personality functioning, family and interpersonal relationships, mental state, diagnosis and a rationale for psychotherapy were presented and considered in detail. The structure of the psychotherapeutic process was reviewed in depth. The hermeneutic guidelines to understanding the case were drawn from Object-Relations Psychoanalytic theory, particularly Balint, Khan, Karon & VandenBos, Bollas, Romanyshyn, Perry, Symington, Fordham and others. Various psychic and personality features, as unveiled through the psychotherapeutic process, were elaborated and the implications of these for the therapeutic endeavour were considered as follows: Firstly, the psychic space of the patient, which precluded mirroring, symbolization find object-relationship - and which made psychotherapy untenable, was discussed. Secondly, therapeutic ambivalence and other counter-transference issues were reviewed. Thirdly, the shadow sides of both therapeutic optimism and of psychotherapeutic change were considered. Fourthly, the issues of therapeutic failure and of other treatment possibilities for a residual schizophrenic patient were examined. It was concluded that there needs to be an important countertransference shift with regard to the psychotherapeutic goals for those patients whose condition may be chronic, and for whom it appears that psychotherapy is not going to be of any therapeutic benefit - find where an 'empathic accompaniment' might be as much as it is possible to hope for or achieve.

Full text

Abstract:

The continued investigation into the experiences of individuals with schizophrenia who participate in biomedical research trials is necessary in order to understand participants’ perspectives, motivations, attitudes, values, and beliefs. As important stakeholders in the clinical research process, participant feedback is significant and can help shed light on, not only their experiences, but also deepen understandings when it comes to clinical trial participants’ perceptions of informed consent and personal autonomy. Conducting ethical research demands the exploration of these issues and specifically targeting this vulnerable group helped to address a gap in the literature. This study was conducted for InSite Clinical Research and gathered data in the form of in-depth semi-structured interviews and a short survey instrument with 20 low-income adults diagnosed with schizophrenia that participate in clinical research trials. Findings indicate overall positive research experiences, with motivations aligning with previous research when it comes to trial participation including: altruism, personal benefit, access to medications, financial incentives, and psychosocial treatment. Learning about their illness and themselves, autonomy, and debriefing were also particularly important within this group. Unique to this sample were findings of friendship. Trust in the research staff was identified as a major underlying value and shaping factor impacting informed consent decisions. These conclusions have implications for recruitment and informed consent practices at InSite Clinical Research.

Abstract:

Thesis (MA. (Psychology)) -- University of the North, 2002.
The aim of the study was to assess as to whether psycho education can lead to compliance,and to strengthen the families to be long-term caregivers in Mankweng hospital (psychiatric clinic) of the Limpopo Province. It is included two phases(l) baseline and (2) follow-up. The baseline included of 82 (50 males and 32 females) participants with schizo phrenia. Their (patients) ages ranged from 17 years to 62 years with the mean age of 37.5 (SD=l 0.2). So, forty-one (41) patients were the experimental group who interviewed and also received intervention , and the remaining forty-one(41) were only interviewed at the baseline. After nine moths , follow-up was done, and it included fifty-seven (36 males and 21 females) participants who were followed up at their homes. Thirty-one (31) were the experimental group and twenty-six (26) were the control group. Their ages ranged from 20 years to 62 years with the mean age 39.3 (SD= l2.6). At follow-up , the questionnaire was going along with the Brief Psychiatric Rating Scale for both groups. The results showed that most of the patients were compliant to their medications however ,with no significant differences because of the small sample that represented the population . For instance , not all patients were available at the follow-up session and there were other factors that could harm the effectiveness of research. The research concludes that psycho-education in South Africa can promise to improve health for the individuals only if the psychiatrists continue to educate patients to be effective on their treatment; and it can provide a concrete approach to the development of social and coping skills of the patients and their families.

Abstract:

The purpose of this study was to describe family members' influence on medication adherence rates for schizophrenic clients following an educational program presented simultaneously to both client and family member. Three chronic schizophrenic clients participated in this study, two were females, and the other was male. The two family members who provided data were husbands of the two female clients. The obtained scores and responses of two questionnaires was indicative of improved medication adherence for clients and family members. The level of adherence was similarly perceived by the clients and their family members as obtained scores and responses were similar across both time periods. However, family members' attendance at the program presentation did not influence the level of reported medicated adherence behaviors of their wives as compared to the client who attended the program alone because the greatest increase in obtained scores was reported by the client who attended the program alone.

Abstract:

Motivations Language has evolved as human’s primary communication tool. It allows us to flexibly manage the amount of information disclosed in communication to deal with complex social situations. Language impairment is a hallmark feature of schizophrenia, which could also be observed to a lesser extent in patients’ unaffected siblings. It significantly affects patients’ social functioning and clinical outcome. Despite ample evidence showing deficits across linguistic levels in schizophrenia, our understanding of patients’ performance in real-life communication, especially under non-cooperative (competitive or tactical) situations, is very limited. In this study we developed a novel method (conversational analysis paradigm, CAP) to investigate both cooperative and competitive communication performance in terms of verbal information value management among patients with schizophrenia and their unaffected siblings compared with healthy controls, and explored their relationships with clinical and cognitive functions. Methods Two studies were conducted. Study one consisted of a validation study (n=40) for CAP and a cross-sectional (n=130) study in investigating verbal information management in schizophrenia and healthy participants. Performance was compared between patients with schizophrenia spectrum disorders (n=65) and matched healthy controls (n=65). Relationships between cognitive functions, clinical features, social competence, and CAP performance were also investigated. In study two, CAP performances were compared among 31 pairs of patients with schizophrenia, their healthy siblings and 31 matched healthy controls (total n=93) to examine verbal information management deficits as a trait in siblings. Schizotypal personality trait was also measured to investigate the potential relationship with CAP in siblings and healthy controls. Results The CAP test demonstrated good inter-rater reliability (ICC 0.82) and adequate internal consistency (Cronbach’s alpha 0.71--‐0.72). Patients showed poorer performance in verbal information management under both cooperative and competitive conditions, which were associated with psychotic symptoms and social functioning. Patients’ poorer cooperatively communicating information, but not competitive controlling information, was associated with their cognitive functions. Performance of patients’ healthy siblings was intermediate between patients and healthy controls, especially during competitive communication. Verbal information management skills were correlated with schizotypal personality trait in siblings but not controls. More deviant verbal information management skills under competitive conditions were closely related to impaired immediate social network in patients and siblings. Discussion This study empirically documented the impaired verbal information management tactics in patients with schizophrenia and their healthy siblings compared using CAP. This specific domain of language impairment was related with cognitive functions, psychotic symptoms, real-life functioning, and schizotypal personality trait. Significance The current study has taken the first attempt to demonstrate an impairment of verbal information transfer in schizophrenia using a newly developed ecological test. Results of this study laid the groundwork for understanding language impairments related to schizophrenia, suggesting verbal information management as a candidate endophenotype of schizophrenia with intervention implications.

Abstract:

This thesis comprises a memoir and essay on schizophrenia. It is estimated that 285,000 people suffer some form of schizophrenia in Australia. This means, on average, one in seventy people in Australia suffer from the disorder. For males, schizophrenia often develops in early adulthood. For females, it has later onset. There are about five types of schizophrenia: paranoid, catatonic, disorganised, undifferentiated, and residual. The focus of this thesis is on the diagnosis of Paranoid Schizophrenia. There is no cure, but it is treatable. However, people with a treatment resistant schizophrenia can find life difficult. The aim of the thesis is to inform people that it is not a condition to fear, and to dispel the stigma often associated with mental illness. Many people shy away from schizophrenics, as the impression given by media is that schizophrenics are dangerous. Another common myth is that schizophrenics have ‘split personality’, which is not the case. The symptoms do not involve multiple personalities. Schizophrenia derives from the Greek, meaning ‘split mind’, and this is where the myth has originated. The focus of the essay is on the historical, cultural and social aspects of schizophrenia. The term schizophrenia was coined in the early twentieth century. The essay looks at ancient texts, where schizophrenia possibly originated in early forms of psychosis. It also considers other cultures, in many of which schizophrenia is stigmatized. Through demystification, the thesis aims to show that it is a medical complaint, rather than a spiritual one. Social aspects include the need for more community support for schizophrenics. This thesis will, hopefully, help to facilitate greater understanding of the condition by providing a personal perspective.

Full text

Abstract:

Semantic clustering has been used as a measure of learning strategies in a number of clinical populations and has been found to be deficient in individuals with Schizophrenia, but less attention has been paid to the dynamic use of this strategy over the course of fixed-order learning trials. In the current study, we examined this pattern of clustering use over trials in a sample of individuals with Schizophrenia, and explored whether the addition of this dynamic information would help us to better predict specific executive deficits. Results suggested that a decrease in semantic clustering across trials was associated with some executive deficits in the predicted manner. Nonetheless, the overall semantic clustering index generally proved more effective for the purposes, suggesting that in this population, the addition of dynamic information in strategy use is not likely to add considerably to clinical prediction and understanding.

Abstract:

The professional component of this thesis focuses on how deinstitutionalisation and the current public mental health system have affected individuals with schizophrenia. Chapter one discusses the process of deinstitutionalisation and the research that has examined the impact of this initiative. Chapter two concentrates on schizophrenia, specifically the symptoms, course, etiological theories and treatments of this illness. Four case studies are then provided in order to explore how deinstitutionalisation and the current mental health system have affected individuals with schizophrenia. The names and identifying characteristics of these clients and their families have been modified to ensure anonymity. Chapter three describes a 47 year old woman, AA, who was referred for a neuro-psychological assessment. Chapter four outlines the second case study, a 23 year old male, BB, who was referred for a psychological assessment regarding diagnosis and treatment recommendations. Chapter five describes the third case study, a 54 year old woman, CC, who was referred for therapy and consultation regarding future treatment recommendations. Chapter six discusses the fourth case study, a 21 year old male, DD, who was seen for crisis intervention and treated in the community. Each of these case studies outlines the background history, formulation and treatment approaches. These case reports are used to illustrate how deinstitutionalisation and the present public mental health system affect individuals with schizophrenia. Chapter seven provides an overall discussion and conclusion to these case studies.

Full text

Abstract:

Objective: Studies in healthy individuals show that exerting self-control consumes cognitive resources, which reduces subsequent self-control performance. This is termed as the self-control depletion effect. Restoring the availability of blood glucose eliminates this impairment, which is deemed as the glucose facilitation effect. Patients with schizophrenia are found to have self-regulatory dysfunctions. This study aims to investigate whether patient’s (a) glucose facilitation effects will be impaired, and (b) will have exaggerated depletion in a self-control task, as compared with healthy population. Method: Forty patients with schizophrenia-spectrum disorders and forty normal controls were recruited. This was a two drinks (glucose vs. placebo) x two depleting phases (self-control depleted vs. non-depleted) between-groups design. We examined the blood glucose levels before and after the self-control depletion phase and the subsequent performances in two self-control tasks (handgrip and Stroop Test) after the drink condition. Results: The four groups (depleting x glucose, depleting x placebo, non-depleting x glucose and non-depleting x placebo) of both patients and normal controls were comparable on a number of characteristics. The change in blood glucose level in the depleting group was significantly different from those in the non-depleting group. Two x two between-subjects ANOVAs were carried out to test the performances in the handgrip and Stroop task. Significant interactions were found in healthy controls regarding both tasks. However, a significant interaction was only found in patients regarding the handgrip task but not the Stroop task. Conclusions: This study demonstrated an impaired glucose facilitation effect in patients during a cognitive self-control task but not physical self-control task. The findings also suggested for the first time that a self-control depletion effect is intact in patients with schizophrenia, comparing with healthy individuals.

Full text

Abstract:

Reward learning refers to outcome-based learning that involves selecting optimal response choices from feedback which facilitate adaptive behavior. It is believed that reward learning paradigm represents a promising translational target in schizophrenia research. Previous studies generated relatively consistent evidence of rapid learning deficits but mixed findings on gradual learning deficits. Reward learning impairments were also associated with symptoms as well as antipsychotics treatment. The current study aimed to investigate the reward learning impairments and its longitudinal change in patients with first-episode schizophrenia spectrum disorder. A total of 34 patients and 36 healthy control participants were recruited. Patients and controls were matched in terms of age, sex, and education level. All participants were assessed twice: at baseline and after one year. For each assessment time point, data were collected on demographics, clinical and treatment characteristics. Participants were asked to complete a battery of cognitive assessments and two reward learning tasks: the Gain vs. loss-avoidance task and the Go-NoGo task. Patients and controls were compared in terms of cross-sectional reward learning performance at baseline and follow-up. Correlates of reward deficits were examined, and longitudinal analyses were conducted to investigate change of reward learning performance over time. At baseline, it was found that patients had significant rapid learning deficit in win-stay (learning from positive feedback) and gradual learning deficits in learning from both positive and negative feedback. Reward-driven learning impairments were more robust. At one-year follow-up, patients continued to have significant rapid learning deficit in win-stay and gradual learning deficits in learning from negative feedback. Longitudinal analyses demonstrated that patients had significant decrease in win-stay rate in training phase and significantly lower accuracy for punishment-driven stimuli across assessment time points. No deficits in representing expected reward value of stimuli or Go response bias were demonstrated. Correlations were found between different symptom domains (negative symptoms, positive symptoms) and reward learning impairments. Current findings regarding rapid and gradual learning deficits in patients with first-episode schizophrenia spectrum disorder were partially in keeping with that of previous studies. Discrepant findings across studies may be attributable to different sample characteristics in terms of illness chronicity and symptoms severity. The current study provided valuable information regarding the longitudinal change of reward learning deficits in early psychosis patients.

Abstract:

The treatment of schizophrenia today consists of a multi-component system of services. Mental health professionals generally agree that anti-psychotic medications are an essential treatment for schizophrenia. However, adherence to medication regimens by patients with schizophrenia is notoriously poor. To identify correlates and predictors of medication compliance, the Schedule for Affective Disorders and Schizophrenia (SADS), a semi-structured diagnostic interview, was administered to 90 outpatients with schizophrenia. The results suggest that there are specific variables (i.e., mood symptoms, psychotic symptoms, and socio-demographic variables) that predict medication compliance. In addition, the confirmation of these variables was effective (90.0%) at identifying non-compliant patients. The results suggest that schizophrenia is a complex disorder composed of heterogeneous symptoms. However, a specific group of symptoms is proposed which may provide a screening measure for predicting patients who are likely to be non-compliant with their medications.

Abstract:

This study is concerned with the assessment of social skill in a remitted schizophrenic sample. It is conducted from the perspective of the social skills model proposed by Argyle and Kendon (1967) expanded in this study. Social impairment can be seen, according to this model, as the result of a breakdown at any part of the social skills cycle. Other workers have conceptualized social skill deficits as the result of anxiety, a limited behavioural repertoire, or faulty cognitive functioning. The advantage of the social skills model is that it provides an explanation of the process of normal social behaviour rather than an explanation solely of impairment (Chapter 1). Severe social impairment may precede, accompany or follow schizophrenic episodes. Much of the theoretical and empirical work on schizophrenia is relevant to the study of the social behaviour of the schizophrenic although few studies have been directly concerned with social skill. Examination of the literature shows that schizophrenics may experience difficulty at every stage of the social skills cycle as a result of factors either associated with the pathology of the disorder, or to the social environment of the schizophrenic {Chapter 2). Social skills assessment has mainly been concerned with assessment of the behavioural response although some procedures have been devised to assess the cognitive aspects of social skill suggested by the social skills model (Chapter 3). This study draws on, and develops tests devised by other researchers in the field and also includes procedures designed specifically for this study. It employs a cross-sectional design to test the hypotheses that there will be differences between schizophrenics and non-schizophrenics in their verbal and non-verbal behaviour, self-cognitions, goals, perception and general social functioning. The subjects were 23 male remitted schizophrenics matched with non-psychiatric controls (Chapter 4). It was found that schizophrenics had very similar goals to the controls, their self-cognitions were extremely negative (although reasonably accurate) and they had difficulty with more complex aspects of social perception. Their patterns of behavioural response were similar to non-schizophrenics although they talked less, made fewer gestures and looked less at their interpersonal partners. They showed little evidence of lack of responsiveness in conversation, although they were generally poor at conversation handovers (Chapters 5 and 6). This study increases our knowledge of the social behaviour of schizophrenics in remission and provides potentially useful information for the design of treatment programmes for this clinical population.

Abstract:

Thesis (MPhil (General Linguistics))—University of Stellenbosch, 2009.
ENGLISH ABSTRACT: The term "schizophrenia" refers to a psychiatric condition which affects an individual's thought and speech (Eaton and Chen 2006). The verbal expression of schizophrenics can therefore be used as a tool for insight into the nature of schizophrenia as well as the cognitive processes of schizophrenics (Wróbel 1990:1). This thesis reports on a comparative evaluation of three pragmatic assessment tools, namely the Pragmatic Protocol (Prutting and Kirchner 1987), the Profile of Communicative Appropriateness (Penn 1985), and the Framework for Assessing (Children's) Conversational Skills (Rumble 1988), in order to establish which of these tools is most suitable for assessing the first language (L1) and second language (L2) pragmatic abilities of late bilingual schizophrenics. Four late bilingual schizophrenic patients participated in this study. A thirty minute informal interview was conducted with each of the participants in both their L1 and L2 and the speech samples were transcribed and then analysed by means of each of the pragmatic assessment tools. A careful examination of the results yielded by the three assessment tools, showed, firstly, that when presenting the results of a pragmatic assessment of schizophrenic speech, it is crucial that both quantitative and qualitative information be included: if the latter is excluded, a significant amount of information is hidden from the clinicians and/or linguists doing the assessment, as well as the people to whom they report their findings. Secondly, with respect to the characteristics of schizophrenic speech, the three instruments used in this study show that whereas most of the aspects of schizophrenics' linguistic abilities seem intact, their pragmatic skills are definitely impaired. Thirdly, regarding differential symptomatology in bilingual schizophrenics, this study concludes that none of the three assessment tools contributes to a better understanding of this phenomenon, and that, in fact, it is highly unlikely that any pragmatic assessment tool would be able to capture this phenomenon. Finally, it is recommended that clinicians assess bilingual patients in both languages, whenever possible, in order to determine the full range of symptoms experienced by the patient, to gain a better indication of the severity of the illness and to track the progress of the illness.
AFRIKAANS OPSOMMING: Die term "skisofrenie" verwys na 'n psigiatriese toestand wat 'n individu se denkprosesse en spraak beïnvloed (Eaton en Chen 2006). Die verbale uitinge van skisofrene kan dus gebruik word om insig oor die aard van skisofrenie, sowel as die kognitiewe prosesse van skisofrene, te verkry (Wróbel 1990:1). Hierdie tesis lewer verslag oor 'n vergelykende evaluering van drie pragmatiese assesseringsinstrumente, naamlik die "Pragmatic Protocol" (Prutting en Kirchner 1987), die "Profile of Communicative Appropriateness" (Penn 1985), en die "Framework for Assessing (Children's) Conversational Skills" (Rumble 1988), om sodoende vas te stel watter een van hierdie drie die mees gepaste instrument is vir die assessering van tweetalige skisofrene se pragmatiese vaardighede in hul eerstetaal (T1) en tweedetaal (T2), spesifiek in gevalle waar die T2 later (d.w.s. nie binne die eerste sewe lewensjare nie) verwerf is. Vier sulke tweetalige skisofrene het deelgeneem aan die studie. Daar is met elkeen van die deelnemers 'n informele onderhoud gevoer vir 30 minute in hul T1, gevolg deur 30 minute in hul T2. Die onderhoude is getranskribeer en daarna geanaliseer deur middel van elk van die drie assesseringsinstrumente. 'n Noukeurige ondersoek en vergelyking van die resultate van die drie instrumente het eerstens getoon dat dit belangrik is om die resultate van 'n pragmatiese analise van skisofreniese spraak op beide 'n kwantitatiewe en kwalitatiewe wyse aan te bied: wanneer kwalitatiewe inligting weggelaat word, bly 'n betekenisvolle hoeveelheid van die informasie verborge vir die klinici en/of taalwetenskaplikes wat die assessering doen, asook die mense aan wie hulle hulle bevindinge rapporteer. Tweedens, met betrekking tot die eienskappe van skisofreniese spraak, wys die drie instrumente wat in hierdie studie gebruik is dat alhoewel meeste aspekte van skisofrene se taalvaardighede ongeskonde is, hulle pragmatiese vaardighede ooglopend aangetas is. Derdens, rakende differensiële simptomatologie in tweetalige skisofrene kom hierdie studie tot die gevolgtrekking dat geen van die drie instrumente bydra tot 'n beter begrip van hierdie verskynsel nie, en dat dit selfs hoogs onwaarskynlik is dat enige pragmatiese assesseringsinstrument hierdie verskynsel sou kon vaslê. Uiteindelik word daar aanbeveel dat klinici, wanneer dit ookal moontlik is, tweetalige pasiënte in beide tale behoort te assesseer om sodoende die volledige reeks van simptome wat 'n pasiënt ervaar vas te stel, om 'n beter aanduiding te bekom oor die erns van die siekte, en om die progressie van die siekte te volg.

Abstract:

Disengagement from mental health services by patients with schizophrenia spectrum disorders is an important issue. Most research in this area has been focused on studying the patients’ demographic and clinical characteristics that may be related to disengagement. However, research on patients’ perspective in regard to their decision of disengagement has been limited. An assessment tool developed based on an in--‐‑depth understanding of patients’ subjective experiences may capture other crucial factors. This may widen our scope of understanding of this phenomenon. Therefore, a mixed research method was employed in this thesis and three independent studies with distinctive research aims were carried out. The first study was a qualitative study which aimed at exploring reasons and factors that patients perceived influential to their decision of disengagement. Six ever--disengaged male patients aged between 18 and 28 with schizophrenia spectrum disorder were interviewed as a purposive sample after a thorough subject identification procedure. A thematic analysis of the data yielded seven themes which grouped into three domains: service (patient--‐‑clinician communication, service orientation, clinic operation); patient (psychological response, perception of illness); and medication (side effects and uncertain efficacy). A 16--‐‑item self--‐‑administered questionnaire, the Patient’s Perception of Psychiatric Service (PPPS) questionnaire, was developed. The construction of PPPS was based entirely on the themes identified from the first qualitative study. This questionnaire measured the subjective perception of the patient about the service and patient--clinician communication. Validation of the PPPS questionnaire was conducted in the second study by recruiting 50 patients with a diagnosis of a schizophrenia spectrum disorder from a psychiatric outpatient clinic. Results demonstrated that the PPPS questionnaire has good internal consistency, test-retest reliability, and convergent validity. The Singh O'ʹBrien Level of Engagement Scale (SOLES), Client Satisfaction Questionnaire (CSQ), and an internalized stigma scale were also translated and validated in this study for use in the third study. The third study explored the relationship between disengagement and the patient’s perception of service, using PPPS, level of engagement (SOLE), satisfaction with service (CSQ), and other factors including clinical characteristics and service utilization. One hundred and fifty patients with schizophrenia spectrum disorder were recruited from two specialized outpatient clinics. In view of local clinical observation, patients who had more than one disengagement episode and each lasted more than two weeks were classified into the severe--‐‑disengagement group. In a forward stepwise regression model, results suggested that PPPS and length of service predict severe disengagement. In this thesis, the use of mixed study methods showed that it was pertinent to incorporate patients’ first person experience into an assessment tool. Measuring patients’ perception of service, by using PPPS, can effectively identify patients with severe disengagement history. PPPS as a patient--‐‑rated self--‐‑administered questionnaire can be used in clinical settings to enhance the understanding of a patient’s appraisal of the service and thus proactive measures can be taken to reduce service disengagement.
