VR-SOAP, a modular virtual reality treatment for improving social activities and participation of young people with psychosis: a study protocol for a single-blind multi-centre randomized controlled trial

BACKGROUND

Young people with a psychotic disorder have the same social goals as their healthy peers, but their social networks are smaller, they participate less often in leisure activities and are less successful in work and education. Causes of these problems are multifaceted, but culminate in difficulties with interacting in daily life social situations. Current treatments have only moderate effects on social functioning and often target one specific domain. Virtual reality (VR) has the potential to improve the treatment of social interaction difficulties. We developed a modular VR treatment for social functioning and participation (VR-SOAP). In this study, the effect of this intervention will be investigated in a randomized controlled trial (RCT).

METHODS

A total of 116 participants (age 18-40) with a DSM-5 diagnosis of schizophrenia spectrum or other psychotic disorder and problems with social functioning will be recruited from mental healthcare institutes in the Netherlands. Participants will be randomized to the experimental condition (VR-SOAP) or active VR control condition (VRelax). VR-SOAP consists of 14 sessions and 5 modules addressing causes of impaired social functioning: four optional modules (1-4) and one fixed module (5). Vrelax consists of 14 sessions that entail psychoeducation, stress management, relaxation techniques, and the exploration of relaxing environments in VR. Primary outcomes are quantity and quality of social contacts, leisure activities and social participation, measured with the experience sampling method (ESM). Secondary outcomes are psychiatric symptoms, social behaviour, social cognition, self-esteem, self-stigma and paranoid thoughts. Treatment effects will be compared at pre-treatment (baseline), post-treatment and at 6-month follow-up.

DISCUSSION

If VR-SOAP proves to be effective, it provides therapists with a much-needed tool to improve social functioning of young adults with a psychotic disorder. Additionally, since the treatment consists of multiple modules targeting different transdiagnostic factors, this trial might provide input for new treatments to improve social functioning in a range of symptoms and disorders, e.g. mood, autism spectrum and anxiety disorders.

On the 10th of November 2021, this trial was registered prospectively in the Dutch Trial Register as NL9784 .

Cross-disorder and disorder-specific deficits in social functioning among schizophrenia and alzheimer's disease patients

Background

Social functioning is often impaired in schizophrenia (SZ) and Alzheimer’s disease (AD). However, commonalities and differences in social dysfunction among these patient groups remain elusive.

Materials and methods

Using data from the PRISM study, behavioral (all subscales and total score of the Social Functioning Scale) and affective (perceived social disability and loneliness) indicators of social functioning were measured in patients with SZ (N = 56), probable AD (N = 50) and age-matched healthy controls groups (HC, N = 29 and N = 28). We examined to what extent social functioning differed between disease and age-matched HC groups, as well as between patient groups. Furthermore, we examined how severity of disease and mood were correlated with social functioning, irrespective of diagnosis.

Results

As compared to HC, both behavioral and affective social functioning seemed impaired in SZ patients (Cohen’s d’s 0.81–1.69), whereas AD patients mainly showed impaired behavioral social function (Cohen’s d’s 0.65–1.14). While behavioral indices of social functioning were similar across patient groups, SZ patients reported more perceived social disability than AD patients (Cohen’s d’s 0.65). Across patient groups, positive mood, lower depression and anxiety levels were strong determinants of better social functioning (p’s <0.001), even more so than severity of disease.

Conclusions

AD and SZ patients both exhibit poor social functioning in comparison to age- and sex matched HC participants. Social dysfunction in SZ patients may be more severe than in AD patients, though this may be due to underreporting by AD patients. Across patients, social functioning appeared as more influenced by mood states than by severity of disease.

A systematic review of social functioning outcome measures in schizophrenia with a focus on suitability for intervention research

Social functioning is an important part of recovery and a key treatment target in clinical research in schizophrenia. Evaluating and comparing interventions is challenged by the choice of many measures which focus on different aspects of functioning, with little to guide selection. This results in difficulties comparing outcomes of treatment where studies have used different measures. To improve the measurement of social functioning in intervention research, we aimed to provide practical information on suitability of measures. We conducted a systematic review of measures developed or psychometrically evaluated since 2007, and assessed and discussed the structure, content, quality, and the use of the measures in intervention research. Thirty-two measures of social functioning and 22 validation papers were identified. Measures included structured questionnaires, semi-structured interviews, and assessment of performance on specific tasks. The content of measures was organised into eight categories, which are in order of frequency with which they were covered by measures: activities of daily living, productive activity, relationships, leisure activities, cognition, anti-social behaviour, psychosis symptoms and self-esteem and empowerment. In terms of quality, most measures were rated as moderate, with the Personal and Social Performance Scale gaining the highest rating. However, there was little data on responsiveness of measures, or how they compare to objective or 'real-world' indicators of functioning. The Social Functioning Scale and Personal and Social Performance Scale have been most frequently used in intervention studies to date. Future research should aim to provide further data on psychometric properties relevant to intervention research.

Affective lability and social functioning in severe mental disorders

Social functioning is impaired in severe mental disorders despite clinical remission, illustrating the need to identify other mechanisms that hinder psychosocial recovery. Affective lability is elevated and associated with an increased clinical burden in psychosis spectrum disorders. We aimed to investigate putative associations between affective lability and social functioning in 293 participants with severe mental disorders (schizophrenia- and bipolar spectrum), and if such an association was independent of well-established predictors of social impairments. The Affective Lability Scale (ALS-SF) was used to measure affective lability covering the dimensions of anxiety-depression, depression-elation and anger. The interpersonal domain of the Social Functioning Scale (SFS) was used to measure social functioning. Correlation analyses were conducted to investigate associations between affective lability and social functioning, followed by a hierarchical multiple regression and follow-up analyses in diagnostic subgroups. Features related to premorbid and clinical characteristics were entered as independent variables together with the ALS-SF scores. We found that higher scores on all ALS-SF subdimensions were significantly associated with lower social functioning (p < 0.005) in the total sample. For the anxiety-depression dimension of the ALS-SF, this association persisted after controlling for potential confounders such as premorbid social functioning, duration of untreated illness and current symptoms (p = 0.019). Our results indicate that elevated affective lability may have a negative impact on social functioning in severe mental disorders, which warrants further investigation. Clinically, it might be fruitful to target affective lability in severe mental disorders to improve psychosocial outcomes.

Participating in Longitudinal Observational Research on Psychiatric Rehabilitation: Quantitative Results From a Patient Perspective Study

BACKGROUND

Longitudinal observational studies play on an important role for evidence-based research on health services and psychiatric rehabilitation. However, information is missing about the reasons, why patients participate in such studies, and how they evaluate their participation experience.

METHODS

Subsequently to their final assessment in a 2-year follow-up study on supported housing for persons with severe mental illness, n = 182 patients answered a short questionnaire on their study participation experience (prior experiences, participation reasons, burden due to study assessments, intention to participate in studies again). Basic respondent characteristics as well as symptom severity (SCL-K9) were also included in the descriptive and analytical statistics.

RESULTS

To help other people and curiosity were cited as the main initial reasons for study participation (>85%). Further motives were significantly associated with demographic and/or clinical variables. For instance, "relieve from boredom" was more frequently reported by men and patients with substance use disorders (compared to mood disorders), and participants 'motive" to talk about illness" was associated with higher symptom severity at study entry. Furthermore, only a small proportion of respondents indicated significant burdens by study participation and about 87% would also participate in future studies.

CONCLUSIONS

The respondents gave an overall positive evaluation regarding their participation experience in an observational study on psychiatric rehabilitation. The results additionally suggest that health and social care professionals should be responsive to the expectations and needs of patients with mental illness regarding participation in research.

Effectiveness of supported housing versus residential care in severe mental illness: a multicenter, quasi-experimental study

PURPOSE

Up to now there are only few studies and no RCT comparing efficacy or effectiveness of supported housing (SH) versus residential care (RC) in severe mental illness (SMI) without homelessness. Here we present an observational follow-up study in SMI subjects, who entered SH or RC, to compare clinical and functional outcomes 2 years later.

METHODS

In this prospective study in more than 30 locations throughout a German federal state, we included SMI subjects, who entered SH (n = 153) or RC (n = 104). About one quarter suffered from each substance use, psychotic, affective, or other disorders. To avoid sampling bias, we used the propensity score matching method to establish a quasi-experimental design. Outcome measures were social functioning (SFS), the number of psychiatric hospitalisations, psychopathology (SCL-9-K), and quality of life (MANSA). Apart from descriptive methods we analysed primarily using repeated-measures ANOVAS.

RESULTS

Our analyses revealed significant effects of time for all outcomes in both study groups. However, there were not any group differences of outcome measures, i.e., not any significant effects of group or interactional effects of group x time. Moreover, these results hold true for intent-to-treat and per-protocol sample analyses.

CONCLUSION

The results show, that SH and RC for non-homeless people with SMI achieve the same clinical and psychosocial outcomes across a 2-year period. Taking into account the users' preferences, the present findings should give reason to ensure the availability of affordable housing and to support the expansion of supported housing approaches.

Independent Supported Housing for non-homeless individuals with severe mental illness: Comparison of two effectiveness studies using a randomised controlled and an observational study design

BACKGROUND

No randomised controlled study (RCT) on the effectiveness of Independent Supported Housing (ISH) vs. housing as usual (HAU) settings for non-homeless individuals with severe mental illness (SMI) has been conducted to date because of limited feasibility. Alternative designs, such as observational studies, might be suitable for providing adequate evidence if well conducted. To test this hypothesis, this article reports on a prospective, direct comparison of the designs of two parallel studies in this field.

METHODS

A two-centre, parallel-group non-inferiority effectiveness study was conducted at two locations in Switzerland using identical instruments and clinical hypotheses. One centre applied an RCT design and the other an observational study (OS) design with propensity score methods (ClinicalTrials.gov: NCT03815604). The comparability of the two study centres was investigated in terms of participants, procedures, and outcomes. The primary outcome was social inclusion and the secondary outcomes were quality of life and psychiatric symptoms.

RESULTS

The study included 141 participants (RCT: n = 58; OS: n = 83). Within one year, 27% study dropouts occurred (RCT: 34%; OS: 22%). A similar balance of sample characteristics was achieved in the RCT and the OS using propensity score methods (inverse probability of treatment weighting). After one year, ISH was non-inferior to the control condition regarding social inclusion (mean differences [95% CI]) in the RCT (6.28 [-0.08 to 13.35]) and the OS (2.24 [-2.30 to 6.77]) and showed no significant differences in quality of life (RCT: 0.12 [-0.52 to 0.75]; OS: 0.16 [-0.26 to 0.58]) and symptoms (RCT: -0.18 [-0.75 to 0.40]; OS: 0.21 [-0.17 to 0.60]) in both study centres. However, strong and persistent preferences for ISH in the RCT control group reduced participants' willingness to participate. Because of several limitations in the RCT, the results of the RCT and the OS are not comparable.

CONCLUSION

Participants were comparable in both study sites. However, there were significant problems in conducting the RCT because of strong preferences for ISH. The OS with propensity score methods provided results of more stable groups of participants and revealed balanced samples and valid outcome analysis. Our results do not support further investment in RCTs in this field.

Independent Supported Housing for Non-homeless People With Serious Mental Illness: A Pragmatic Randomized Controlled Trial

BACKGROUND

Independent supported housing (ISH)-services to support independent housing are recommended by current guidelines. However, there is little evidence of ISH models for non-homeless people with severe mental illness (SMI). The aim of this study was to examine the effectiveness of ISH by comparing the clinical outcomes of a newly implemented ISH service with regular housing and support services.

METHODS

A total of 58 adults with a broad spectrum of mental disorders experiencing housing problems were randomly assigned to either the intervention group (IG) with the possibility to use the ISH service in Zurich providing targeted, individual and flexible support for housing problems or to the control group (CG) with regular housing and support services currently available (trial registration at ClinicalTrials.gov: NCT03815604).

RESULTS

After 12 months, almost all participants of the IG were able to live independently and need for inpatient treatment could be significantly reduced. Service utilization varied between 2 and 79 h. In the CG, 70% of the participants wanted to join a waiting list for the ISH service. The results indicated that IHS was comparable to regular housing and support services in terms of social inclusion and other social and clinical outcomes such as quality of life, capabilities, needs, mental state and functioning (p's > 0.05). The costs of service utilization were on average 115 Swiss Francs (about 124 USD) per participant per month.

CONCLUSIONS

ISH is an effective service in housing rehabilitation in terms of social and clinical outcomes and costs. ISH is strongly preferred by service users. In line with the UN Convention on the Rights of Persons with Disabilities, access to ISH services for non-homeless people with SMI should be improved.

Effects of motivation domains on social functioning in schizophrenia with consideration of the factor structure and confounding influences

In patients with schizophrenia, motivation has been assumed to act as an intervening factor between cognitive function and social functioning. Motivation is thought to comprise three domains defined by their orientations: intrinsic motivation, extrinsic motivation, and amotivation. Although these orientations can confound each other, the effects of motivation domains on social functioning remain obscure. We investigated these relationships after confirming the factor structure of social functioning using the Social Functioning Scale (SFS). A total of 97 stable outpatients with schizophrenia were recruited. In addition to the SFS, the General Causality Orientations Scale (GCOS) was used to measure the motivation domains. First, we examined the factor structure of the SFS using exploratory and confirmatory factor analyses. Next, we conducted structural equation modeling to examine the effects of motivation domains on social functioning. The SFS showed a two-factor structure: interpersonal and intrapersonal functioning. The structural equation model revealed that (1) amotivation was negatively related to both intrapersonal and interpersonal functioning, (2) intrinsic motivation was positively related only to intrapersonal functioning, and (3) extrinsic motivation was positively related only to interpersonal functioning. Each motivation domain was associated with different factors of social functioning. Future interventions aimed at improving social functioning should consider these motivation domains based on their orientations. Cognitive remediation accompanied by considerations for and approaches to each of the domains may maximize recovery in patients with schizophrenia.

Independent Housing and Support for non-homeless individuals with severe mental illness: randomised controlled trial vs. observational study - study protocol

BACKGROUND

Social inclusion is essential for an adequate rehabilitation process for people with serious mental illness (SMI). Various supported housing settings aim to promote housing competencies and social inclusion in service users. Nevertheless, there is a strong preference in service users for independent living. We aim to evaluate the effectiveness and efficiency of Independent Housing and Support (IHS) compared to institutionalised residential care settings and other treatment as usual conditions (RCS/TAU) in two cities in Switzerland.

METHODS

This is a prospective multi-centre, four-arm, non-inferiority cohort study investigating the effectiveness and efficiency of IHS and RCS/TAU for people with SMI. Effectiveness will be measured by a standardised measure of social inclusion as primary outcome as well as by measures of functioning and well-being. Efficiency will be analysed on the basis of service usage and costs associated with the different housing settings. Participants will be consecutively recruited and subsequently enrolled between April 2019 and December 2020 and assessed at baseline and after six, twelve and after 24 months. At one study site, 56 participants will be randomly assigned to one of the conditions; the other study site will be conducted as an observational study investigating 112 admitted participants.

DISCUSSION

While the UN Convention of the Rights of People with Disabilities aims to promote the opportunity to choose one's place of residence, the limited supply of alternative forms of housing does not guarantee genuine freedom of choice. Increased diversification and flexibility of housing support is essential. If IHS shows non-inferiority in terms of their effectiveness and efficiency, users should be allowed to choose their kind of housing support.

Basic self-disturbances are associated with Sense of Coherence in patients with psychotic disorders

Background

The Sense of Coherence (SOC) theory gives a possible explanation of how people can experience subjective good health despite severe illness. Basic self-disturbances (BSDs) are subtle non-psychotic disturbances that may destabilize the person’s sense of self, identity, corporeality, and the overall ‘grip’ of the world.

Aim

Our objective was to investigate associations between BSDs and SOC in patients with psychotic disorders.

Design

This is a cross-sectional study of 56 patients diagnosed with psychotic disorders inside and outside the schizophrenia spectrum (35 schizophrenia, 13 bipolar, and eight other psychoses). SOC was measured using Antonovsky’s 13-item SOC questionnaire, and BSDs were assessed using the Examination of Anomalous Self-Experience (EASE) manual. Diagnosis, symptoms, and social and occupational performance were assessed using standardized clinical instruments.

Results

We found a statistically significant correlation (r = ) between high levels of BSDs and low levels of SOC (r = -0.64/p<0.001). This association was not influenced by diagnostics, clinical symptoms or level of functioning in follow-up multivariate analyses.

Conclusion

A statistically significant association between BSDs and SOC indicates that the presence and level of self-disturbances may influence the person's ability to experience life as comprehensive, manageable and meaningful. However, the cross-sectional nature of the study precludes conclusions regarding the direction of this association.

Determinants of clinical, functional and personal recovery for people with schizophrenia and other severe mental illnesses: A cross-sectional analysis

OBJECTIVE

To analyze the relationships between insight, medication adherence, addiction, coping and social support-components of Illness Management and Recovery (IMR)-as determinants of clinical, functional and personal recovery in patients with schizophrenia and other severe mental illnesses. Our rationale lay in the interrelations between these concepts suggested in a conceptual framework of IMR.

METHODS

The cross-sectional design used baseline data of outpatient participants in a randomized clinical trial on IMR (N = 187). We used structural equation modeling (SEM) to describe pathways between degrees of insight, medication adherence, addiction, coping and social support, and degree of clinical, functional and personal recovery. We also explored whether clinical recovery mediated functional and personal recovery.

RESULTS

Our final model showed that coping was associated with clinical, functional and personal recovery. Direct associations between coping and functional and personal recovery were stronger than indirect associations via clinical recovery. Although SEM also showed a significant but weak direct pathway between social support and functional recovery, there were no significant pathways either between social support and clinical or personal recovery, or between insight, medication adherence, addiction and any type of recovery.

CONCLUSIONS

Coping may be a determinant of all three types of recovery, and social support a determinant of functional recovery. Clinical recovery appears not to be a prerequisite for functional or personal recovery. While our results also suggest the relevance of improving coping skills and of enhancing social support, they only partially support the conceptual framework of IMR.

A 1.5-Year Longitudinal Study of Social Activity in Patients With Schizophrenia

Patients with schizophrenia exhibit impairments in their social activity, intelligence quotient (IQ), daily living skills, and social function. Social activity is a high-order outcome measure of their lives. Here we attempted to longitudinally evaluate the effects of IQ, daily living skills, social function, psychiatric symptoms, and medications on social activity in patients with schizophrenia. The purpose of the current study is to identify the specific factor that affects longitudinal changes in social activity. Sixty-five patients with schizophrenia were assessed at two time points [time 2 (T2, follow-up) - time 1 (T1, baseline) = 1.71 ± 0.79 years]. Social activity, IQ, daily living skills, and social function were assessed using the Social Activity Assessment (SAA; h/week), short form of the Wechsler Adult Intelligence Scale (WAIS)-III (WAIS-SF), University of California San Diego (UCSD) Performance-Based Skills Assessment (UPSA), and Social Functioning Scale (SFS), respectively. IQ, daily living skills, social function, and social activity were significantly improved between T1 and T2 (t = 2.0-4.4, p = 0.048-3.60 × 10-5). IQ, daily living skills, and social function positively correlated with social activity (lowest p = 1.27 × 10-5), and psychiatric symptoms negatively correlated with social activity over time (lowest p = 3.26 × 10-9). The longitudinal change in social activity was independently and positively correlated with a change in social function (beta = 0.35, p = 4.63 × 10-3), particularly interpersonal communication (beta = 0.35, p = 4.32 × 10-3). The longitudinal changes in other factors did not directly affect the change in social activity (p > 0.05). Based on these findings, social activity is more affected by social function than by other factors.

Validation of the social functioning scale: Comparison and evaluation in early psychosis, autism spectrum disorder and social anxiety disorder

Social functioning is an important component of mental disorders for assessment and treatment. There is no recognised self-report instrument to measure social functioning across disorders where social impairment is significant. The Social Functioning Scale (SFS) has, however, been used to assess social functioning in psychotic disorders, including Schizophrenia and Early Psychosis. The current study investigated the reliability, validity and sensitivity of the SFS in Early Psychosis, Autism Spectrum Disorder (ASD), Social Anxiety Disorder (SAD) and neurotypical control populations. As expected, all clinical groups showed significant impairment on the total and sub-scale scores of the SFS. The SFS showed good internal consistency and concurrent validity for people diagnosed with SAD and Early Psychosis and a similar factors structure was found for these groups. Participants with ASD reported a relatively low internal consistency and poor concurrent validity, as well as a three-component solution. The SFS has also showed a good sensitivity to separate clinical populations and neurotypical controls. This study supports the use of the SFS for those with SAD and Early Psychosis. Lower internal consistency in ASD populations suggests further research in larger samples is required and that the relationship between its scales are likely different to other populations. Alternative scales or significant other reports may be required for adults with ASD.

Profiling of victimization, perpetration, and participation: A latent class analysis among people with severe mental illness

BACKGROUND

Persons with severe mental illness are more prone to victimization and experience more difficulties regarding societal participation than other community members. These experiences vary greatly among individuals. Community mental health care should offer more individualized support by addressing these differences in experience. Therefore, this study aimed to identify subgroups of outpatients with severe mental illness based on their experiences of social participation and victimization.

METHODS

Data from patients with severe mental illness from eight outpatient teams in the Netherlands were used to perform latent class analysis. From the total caseload, 395 patients agreed to participate. Classes were based on: i) criminal victimization incidents, ii) criminal perpetration incidents (Dutch Safety Monitor), iii) experienced discrimination (DISC-12), and iv) social functioning (Social Functioning Scale). Also, to investigate differences between the classes, socio-demographic, clinical, and person-related variables were examined.

RESULTS

Three classes were identified. The Victimized and Perpetrating class (34.4%) had the highest prevalence of discrimination, victimization, and perpetration, and intermediate scores on social functioning subscales. This class also experienced the most problems in other domains, such as psychosocial functioning and quality of life. The Discriminated and Avoiding class (36.4%) had moderate scores for discrimination, victimization and perpetration, and the lowest scores for social functioning and social support. The General Difficulties class (28.8%) had the lowest prevalence of discrimination, victimization, and perpetration, and the highest scores on social functioning.

DISCUSSION

These distinct classes offer new insights to mental health professionals in outpatient teams in in their aim to positively influence the patient's social context during rehabilitation; this includes addressing the role of victimization, and indicates the relevance of distinctive approaches and the support needed for each class. Professionals may need to focus more on the impact of difficulties in their patients' social context to adequately support them in the rehabilitation process.

Effectiveness of an intervention for managing victimization risks related to societal participation for persons with severe mental illness: a cluster RCT study protocol

BACKGROUND

People with severe mental illness (SMI) are more likely to experience criminal victimization than other community members. In addition, (self-) stigma and perceived discrimination are highly prevalent in this group. These adversities in the social context often have major adverse effects on the rehabilitation and recovery of these persons. Current practice, however, lacks instruments to address these issues. As a reaction, the Victoria intervention was developed and pilot-tested with client representatives, professionals, trainers and researchers. The Victoria intervention is a method for community mental health care workers to expand their awareness of this topic and support them in assessing victimization and incorporate appropriate services, including trauma screening and rehabilitation services, in their health care planning. For clients, the Victoria intervention aims to increase their awareness, active management of possible victimization risks and promote safe social participation. As a new intervention, little is known about its use in real practice and its effects on client outcomes.

METHODS/DESIGN

To determine the feasibility and effectiveness of this intervention, a process evaluation and a first cluster randomized controlled trial (RCT) will be carried out. Outpatients from eight Flexible Assertive Community Treatment (F-ACT) teams from two mental health care (MHC) organizations in the Netherlands are included in the study. Teams in the intervention group will receive three half-day training sessions, and bi-monthly supervision meetings for 18 months. Teams in the control group provide care as usual. For the process evaluation, a multi-method design is used. To assess effects on client outcomes, clients will be interviewed about their experiences on victimization and societal participation using validated questionnaires at baseline, and after 9 and 18 months.

DISCUSSION

This study is the first to evaluate an intervention aiming at recognition of victimization, (self-) stigma and perceived discrimination, and targeting outpatients' insights into possible risks and coping skills to tackle these risks to enhance safe societal participation. Results of this study may validate the Victoria intervention as a practice to better manage risk for adversities related to societal participation.

Paranoia and interpersonal functioning across the continuum from healthy to pathological - Network analysis

OBJECTIVE

Previous research has suggested that paranoia is associated with impaired social functioning in patients with schizophrenia and healthy individuals with high levels of paranoid ideation. This study analysed the relationship between paranoia and interpersonal functioning across the paranoia continuum using network analysis.

METHOD

Levels of paranoid ideation and interpersonal functioning were measured in a non-clinical sample (N = 853) and in patients with schizophrenia spectrum disorders (N = 226). Network analyses were used to examine the nature of paranoia's relation to interpersonal functioning in both populations.

RESULTS

Although the most central characteristic of paranoia in both samples was the feeling of being talked about behind one's back, across samples, individual characteristics were differentially related to various aspects of interpersonal functioning. Among clinical individuals, difficulties in interpersonal functioning were related to perceived previous experiences of being treated poorly by others, whereas among the non-clinical sample, interpersonal functioning was related to negative beliefs about others.

CONCLUSIONS

The current results support previous findings linking paranoid ideation to interpersonal functioning in both clinical and non-clinical samples. Patterns of these relationships differed slightly across groups. Results in general support a continuum model of paranoia.

PRACTITIONER POINTS

Network analyses were used to identify central aspects of persecutory ideation in both clinical and non-clinical samples. Qualitative assessment of clinical and non-clinical networks revealed similar central symptoms and supported a continuum model of paranoia. Central aspects of paranoia, that is, feeling that others have talked about oneself behind one's back, being disappointed by others, and having distressing feelings of being watched by others, were associated with deficits in interpersonal functioning in both samples. Central aspects of paranoia may be beneficial targets for psychosocial interventions aimed at reducing paranoid ideation and improving interpersonal functioning. Demographic characteristics for this study differed between samples which may limit generalization of findings. Future research is needed to explore temporal associations and moment-to-moment dynamics between paranoid ideation and problems in interpersonal functioning.

The Effect of Yoga on Functional Recovery Level in Schizophrenic Patients

PURPOSE

The objective of this study is to determine the effect of yoga on functional recovery level in schizophrenic patients.

MATERIALS AND METHODS

The study was conducted in quasi-experimental design with pretest-posttest control group. The population of the study consisted of schizophrenic patients with registered in Malatya and Elazığ Community Mental Health Centers and regularly going to these centers. The sample group of the study consisted of totally 100 patients including 50 patients in the experimental group and 50 patients in the control group who were specified through power analysis and chosen by using random sampling method from this population. The data were collected between April 2015 and August 2015. 'Patient Description Form' and 'FROGS' were used to collect the data. Yoga was applied to patients in the experimental group. Any intervention was not made to patients in the control group. Percentage distribution, arithmetic mean, standard deviation, chi-square, independent samples t test, and paired t test were used to assess the data.

RESULTS

Patients in the control and experimental group pretest subscale and the total means scores of FROGS was found to be low. In the posttest subscale and total means scores of FROGS in the experimental group were higher than in the control group and the differences between them were found to be statistically significant (p<0.05). In the experimental group pretest and posttest subscale and total means scores of FR0GS was determined to be statistically significant (p<0.05).

CONCLUSION

Yoga that applied to schizophrenic patients it was determined to increased the level of functional recovery. It can be suggested that yoga should be used as an complementary method in nursing practise in order to increase the effectiveness of the treatment.

Social Functioning and Self-Esteem of Substance Abuse Patients

AIM

This descriptive study was conducted to examine the levels of social functioning and self-esteem in individuals diagnosed with substance abuse.

MATERIAL AND METHOD

The study was conducted at the AMATEM (Alcohol and Substance Abuse Treatment Center) service of a psychiatry clinic in the Elazığ province in eastern Turkey between September 1, 2014 and February 1, 2015. The population is comprised of 249 patients being treated in this clinic, and the sample included 203 patients who comply with the research criteria and agreed to participate in the study. A Socia-Demographic Questionnaire, Coopersmith Self-esteem Scale (CSI) and Social Functioning Scale (SFS) were used for data collection. Percentages, averages, standard deviations and Pearson's correlation were used for data analysis.

RESULTS

This study found that the patients' mean sore on the Self-esteem Scale is 50.97±18.01. Their score on the Social Functioning Scale is 115.76±22.41. A significant correlation between the patients' self-esteem and the age of first substance use was detected (p=0.001). A significant correlation was detected between their social functioning and the duration of their substance use (p<0.005). This study found a positive significant correlation between social functioning and self-esteem (p<0.001).

CONCLUSION

This study found that substance abuse patients have a medium level of self-esteem and social functioning. A significant positive correlation between social functioning and self-esteem was found. It was also found that the age of first substance use and self-esteem are directly correlated. Counseling to increase patients' levels of self-esteem and improve their social functioning is recommended.
