Exploratory and confirmatory factor analyses of the Multidimensional Scale of Perceived Social Support in patients with schizophrenia

Sense of mastery in first-episode psychosis-a one-year follow-up study

Introduction

A sense of mastery refers to beliefs about having control over one's life and has been found to protect health and buffer the effect of stressful experiences.

Methods

We investigated sense of mastery in first-episode psychosis (FEP) patients and population controls at baseline and at one-year follow-up. Pearlin and Schooler's Sense of Mastery scale was completed by 322 participants at baseline and by 184 participants at follow-up.

Results

People having experienced FEP reported lower mastery than controls at both time points, but a modest increase was seen in patients at follow-up. The strongest correlates of high baseline mastery in FEP were lower depressive symptoms and higher perceived social support, whereas positive or negative psychotic symptoms did not associate with mastery. Current depressive symptoms also correlated with mastery at the follow-up point, and change in depressive symptoms correlated with change in mastery. Higher mastery at treatment entry predicted remission of psychotic symptoms one year later. Sense of mastery was also found to mediate the association of perceived social support with depressive symptoms.

Discussion

The usefulness of mastery measures should be further tested for estimations of patient prognosis in early psychosis.

Cut points and sensitivity to change of the Enfranchisement scale of the Community Participation Indicators in adults with traumatic brain injury

BACKGROUND

Community participation is an important outcome of rehabilitation following traumatic brain injury. Yet, few measures assess inclusion and belonging (enfranchisement) as a dimension of community participation. The Enfranchisement scale of the Community Participation Indicators addresses this need. However, research on its psychometric properties is lacking.

OBJECTIVE

To examine cut points and sensitivity to change of the Enfranchisement scale of the Community Participation Indicators in adults with traumatic brain injury.

DESIGN

This was a repeated measures study with assessments administered twice (3 months apart).

SETTING

Assessments were administered either over the phone, virtually (Zoom), or in person at the participant's home.

PARTICIPANTS

A total of 44 participants from community settings who had either experienced a traumatic brain injury within the previous year or were receiving rehabilitation interventions were recruited.

MAIN OUTCOME MEASURE

The Enfranchisement scale has two subscales: the Control subscale (range: 13-65) and the Importance subscale (range: 14-70). On both subscales, lower scores indicate better enfranchisement.

METHODS

The software SAS PROC Logistic and the macro %ROCPlot were used to examine cut points at varying levels of sensitivity and specificity. The area under the receiver operating characteristics curve was calculated to determine overall classification accuracy. Minimum detectable change and minimal clinically important difference were also calculated.

RESULTS

For the Control subscale, a cut point of 44 (area under the curve = .75), a minimum detectable change of 8, and a minimal clinically important difference of 5 were found. For the Importance subscale, a cut point of 39 (area under the curve = .81), a minimum detectable change of 8, and a minimal clinically important difference of 5 were found.

CONCLUSIONS

The cut points resulted in good classification accuracy, providing support for their reliability. The results provided evidence that both subscales are sensitive to change in adults with brain injury.

Validation of Multidimensional Scale of Perceived Social Support (MSPSS) in Vietnamese Among People Living with HIV/AIDS

Social support plays a vital role in the health of HIV/AIDS patients, but there needs to be a validated instrument to measure social support in Vietnam. This cross-sectional study was to validate a Vietnamese translation of the Multidimensional Perceived Social Support Scale (MSPSS). The study had three stages: [1] translation to Vietnamese, [2] pilot testing, and [3] validation of the translation. Stage 1, including forward and backward translation by four independent translators, resulted in a good content validity translation. Pilot testing was done on 30 HIV/AIDS patients: the translation was understandable, and no change was required. Five hundred HIV/AIDS patients were recruited in stage 3. The translation had excellent internal consistency (Cronbach's alpha: 0.90), good test-retest reliability (intra-class correlation coefficient: 0.95), and good concurrent validity. Construct validity was well established by confirmatory factor analysis. The Vietnamese translation of the MSPSS is reliable and valuable for measuring perceived social support.

Evidence of the validity of the Multidimensional Scale of Perceived Social Support (MSPSS) in university students

Abstract Social support refers to the social resources that a person perceives to be available and has been strongly associated with physical and mental health outcomes. The present study aimed to evaluate the internal consistency, construct validity, and test-retest reliability of the Perceived Social Support Multidimensional Scale (PSSMS) in university students in the Midwest of Brazil. Exploratory and confirmatory factor analyses were performed with two independent random samples, both consisting of 1,147 students. The test-retest study was carried out with a sample of 347 medical students. Data were collected in two separate moments with a 14-day interval. The solution with the best fit was the three-factor model: family, friends, and significant others. The factor loadings of the scale items ranged between 0.767 and 0.950 and each factor showed high internal consistency (Cronbach’s alpha=0.96, 0.97, and 0.97, respectively). The model also attained adequate fit: χ2(d.f.)=380 (49), p<0.0001; SRMR=0.023; RMSEA=0.077; CFI=0.993; TLI=0.990. Test-retest reliability was moderate (weighted kappa ranging from 0.36 to 0.52). The results suggest that the PSSMS has acceptable psychometric properties for use with university students.

Evidências de validade da Escala Multidimensional de Suporte Social Percebido (EMSSP) em universitários

Resumo O apoio social se refere aos recursos sociais percebidos como disponíveis à pessoa e tem sido fortemente associado a desfechos em saúde física e mental. O estudo atual objetivou avaliar a consistência interna, a validação de construto e a confiabilidade teste-reteste da Escala Multidimensional de Suporte Social Percebido (EMSSP) em universitários do Centro Oeste brasileiro. As análises fatoriais exploratória e confirmatória foram realizadas com duas amostras aleatórias e independentes, ambas de 1.147 universitários da área da saúde. O estudo teste-reteste foi realizado com uma amostra de 347 estudantes de medicina e duas coletas com intervalo de 14 dias entre elas. A melhor solução foi com três fatores: família, amigos, e outros significativos, os quais apreesentaram cargas fatoriais variando entre 0,767 a 0,950 e consistência interna elevada (alfa de Cronbach de 0,96, 0,97 e 0,97, respectivamente). O ajustamento para essa solução foi adequado (χ2(g.l.)=380 (49), p<0,001; SRMR: 0,023; RMSEA: 0,077; CFI: 0,993; TLI: 0,990). A confiabilidade teste-reteste foi moderada (Kappa ponderado variando de 0,36 a 0,52). Os resultados sugerem que a EMSSP possui propriedades psicométricas aceitáveis para seu uso com universitários.

The Association of Social Support and Symptomatic Remission among Community-Dwelling Schizophrenia Patients: A Cross-Sectional Study

Schizophrenia is a mental disease that often leads to chronicity. Social support could reduce the severity of psychotic symptoms; therefore, its influence on remission should be examined. This study investigated the remission rates in community-dwelling schizophrenia patients and examined the association between social support and remission status. A cross-sectional study was conducted in 129 schizophrenia patients in Taiwan. Remission rates were evaluated, and the level of social support, clinical characteristics, sociodemographic variables, and healthy lifestyle status were compared between the remission and nonremission groups. The association between social support and remission was analyzed after adjusting for confounding factors. The mean illness duration is 12.9 years. More than 95% of the participants lived with their families, 63% were unemployed, and 43% achieved remission. Higher social support was observed in the remission group, and a significant correlation was observed between family domain of social support and remission status. Family support was a protective factor of symptomatic remission in community-dwelling schizophrenia patients in Taiwan. The results reflect the effects of a family-centered culture on patients during illness. Consequently, reinforcing family relationships and the capacity of families to manage the symptoms of patients and providing support to families are recommended.

Ego-Resiliency and Perceived Social Support in Late Childhood: A Latent Growth Modeling Approach

This study explored the change trajectory of schoolchildren’s ego-resiliency and perceived social support and investigated the effect of perceived social support on ego-resiliency across four time points. A sample of 437 children aged 8–13 years (M = 10.99, SD = 0.70, 51.5% boys) completed assessments at four time points. The results indicated that ego-resiliency showed an increasing linear trend and perceived social support showed a declining linear trend. Perceived social support had a positive effect on ego-resiliency over time. In addition, the initial status of perceived social support negatively predicted the growth trend of ego-resiliency, and the initial status of ego-resiliency negatively predicted the declining trend of perceived social support. The implications for theory and practice are discussed.

Physical Activity Can Enhance Life (PACE-Life): results from a 10-week walking intervention for individuals with schizophrenia spectrum disorders

BACKGROUND

Premature mortality in individuals with schizophrenia spectrum disorders (SSDs) is largely due to high rates of chronic health conditions. Although exercise has been shown to improve health in this population, scalable and accessible interventions are limited.

AIM

To examine the impact of Physical Activity Can Enhance Life (PACE-Life), a novel walking intervention, on physical activity, and on secondary outcomes of cardiorespiratory fitness (CRF), physical health, autonomous motivation, social support, and quality of life.

METHOD

Sixteen individuals with SSDs were enrolled in a 10-week open trial. The intervention included walking groups, home-based walks, Fitbit use, and goal-setting and if-then plans. Within-group effect sizes were calculated to represent changes from baseline to post-test and 1-month follow-up.

RESULTS

Participants increased self-reported weekly walking minutes and decreased daily hours spent sitting; however, Fitbit-recorded exercise behavior changed only minimally. There were also improvements in secondary outcomes including autonomous motivation and hip circumference. CRF improved only minimally, and findings were relatively unchanged with outliers removed from the full sample.

CONCLUSIONS

This open trial demonstrates modest improvements in key parameters of exercise behavior and physical health from participating in PACE-Life. Future research should assess the efficacy of this intervention in a randomized controlled trial.

Measurement Invariance of the Multidimensional Scale of Perceived Social Support Among Chinese and South Asian Ethnic Minority Adolescents in Hong Kong

Seven hundred adolescents (Chinese = 50%; South Asian ethnic minority = 50%) with mean age of 15.3 years (SD = 1.53). Multigroup confirmatory factor analysis was performed to assess measurement invariance of the MSPSS scale across Chinese and South Asian ethnic minority samples. Results show that the original three-factor structure of the MSPSS was supported in both samples. Measurement invariance was supported in terms of configural, metric, and partial scalar invariance. Given partial scalar invariance was achieved, the latent mean differences were compared across samples. Chinese adolescents had higher levels of all three types of social support when compared with their South Asian ethnic minority counterparts. The present study attempts to assess the measurement invariance of the MSPSS across ethnic groups in Asian society, which sheds light on future research that involves perceived social support among adolescents in Chinese culture contexts.

The association of mental disorders with perceived social support, and the role of marital status: results from a national cross-sectional survey

Background

This study investigated whether (i) mental disorders were associated with perceived social support and its subcomponents, (ii) current marital status was related to perceived social support, and (iii) ‘Married’ status influenced the relationship between mental state and perceived social support.

Methods

Data from a cross-sectional national survey comprising 6126 respondents were used. Lifetime diagnosis for five mental disorders was assessed with a structured questionnaire. Perceived social support was measured with the Multidimensional Scale of Perceived Social Support (MSPSS) that provides Global and subscale scores for Significant Other, Family and Friends. Multiple linear regression analyses were conducted to address the research questions with MSPSS score as the dependent variable. Structural equation modeling (SEM) was performed to test mediation by marital status.

Results

All mental disorders included in the study, except alcohol use disorder (AUD), were significantly and negatively associated with Global MSPSS scores. After controlling for sociodemographic factors and chronic physical illness, major depressive disorder (β = - 0.299, 95% CI: -0.484 – -0.113, p = 002) and having any of the five mental disorders (β = - 0.133, 95% CI: -0.254 – -0.012, p = 032) were negatively associated with support from Significant Other, while support from Family and Friends was lower among all disorders, except AUD. Being married was positively associated with perceived social support in people with and without mental disorders. Results of the SEM partially support mediation by mental state - perceived social support relationship by ‘Married’ status.

Conclusion

Having mental disorders was associated with lower perceived social support. Being married has potential to influence this relationship.

Validation of the care providers version of the Rainbow Model of Integrated Care-measurement tool in Chinese primary care systems

Background

The original Rainbow Model of Integrated Care Measurement Tool (RMIC-MT) is based on the Rainbow Model of Integrated Care (RMIC), which provides a comprehensive theoretical framework for integrated care. To translate and adapt the original care provider version of the RMIC-MT and evaluate its psychometric properties by a pilot study in Chinese primary care systems.

Methods

The translation and adaptation process were performed in four steps, forward and back-translation, experts review and pre-testing. We conducted a cross-sectional study with 1610 community care professionals in all 79 community health stations in the Nanshan district. We analyzed the distribution of responses to each item to study the psychometric sensitivity. Exploratory factor analysis with principal axis extraction method and promax rotation was used to assess the construct validity. Cronbach’s alpha was utilized to ascertain the internal consistency reliability. Lastly, confirmation factor analysis was used to evaluate the exploratory factor analysis model fit.

Results

During the translation and adaptation process, all 48 items were retained with some detailed modifications. No item was found to have psychometric sensitivity problems. Six factors (person- & community-centeredness, care integration, professional integration, organizational integration, cultural competence and technical competence) with 45 items were determined by exploratory factor analysis, accounting for 61.46% of the total variance. A standard Cronbach’s alpha of 0.940 and significant correlation among all items in the scale (> 0.4) showed good internal consistency reliability of the tool. And, the model passed the majority of goodness-to-fit test by confirmation factor analysis.

Conclusions

The results showed initial satisfactory psychometric properties for the validation of the Chinese RMIC-MT provider version. Its application in China will promote the development of people-centered integrated primary care. However, further psychometric testing is needed in multiple primary care settings with both public and private community institutes.

Suitability of the multidimensional scale of perceived social support as a measure of functional social support among incarcerated adults with major depressive disorder

The multidimensional scale of perceived social support (MSPSS) is a 12-item measure of functional social support (SS); however, the psychometric properties of the MSPSS have not been evaluated in prisoners. We used measures of known-groups validity, convergent and discriminant validity, internal consistency reliability and factor structure to assess the suitability of the MSPSS for measuring SS among 184 individuals in prison in the U.S., who were diagnosed with depression. The MSPSS was correlated with scores on scales measuring related constructs (i.e., loneliness), and uncorrelated with unrelated constructs (i.e., verbal ability). Correlations among items of the MSPSS on the same subscale were large, and small to moderate among items of different subscales. The overall Cronbach's α for the scale was 0.93. Confirmatory factor analysis showed that the theorized three-factor solution for the MSPSS (i.e., significant other, family, and friends) provided a good fit for the data. We recommend using the MSPSS to measure perceived SS among incarcerated individuals.

Multidimensional Scale of Perceived Social Support in Indonesian adolescent disaster survivors: A psychometric evaluation

BACKGROUND

Social support plays an important role in adolescents' mental health and well-being, and even more so for disaster survivors. To measure the level of social support, one needs an appropriate tool to produce valid and reliable results; therefore, we aimed to measure the invariance across gender groups, and analyze the construct validity and reliability of the Indonesian version of the Multidimensional Scale of Perceived Social Support (MSPSS), a social support measurement tool which was theoretically constructed and has been well validated in many countries with various cultures and backgrounds.

METHODS

A school-based assessment was conducted in junior and senior high schools in a post-disaster setting in Yogyakarta Province, Indonesia. We analyzed 299 adolescent survivors of a volcanic eruption, aged 12~18 years who completed a 12-item Indonesian version of the MSPSS.

RESULTS

The factorial validity confirmed the three-factor structure of the scale (Family, Friends, and Significant Others) which met all of the criteria of parameter indices and provided evidence of high internal consistency reliability. The three-level measurement of invariance, which consisted of configural, metric, and scalar invariance, also performed very well across gender groups with our data and corresponded to the recommended parameters. Our composite reliability values were all fine (>0.7) and indicated that the items in the same construct were strongly correlated and reliable.

CONCLUSIONS

The Indonesian version of the MSPSS was shown to be a valid, reliable, theoretically constructed, and applicable instrument for adolescent disaster survivors.

Obsessive-Compulsive Disorder in Singapore: Prevalence, Comorbidity, Quality of Life and Social Support

Introduction: Using data from Singapore Mental Health Study 2016 (SMHS 2016), we examined the prevalence of lifetime and 12-month obsessive-compulsive disorder (OCD),its sociodemographics correlates and association with comorbid psychiatric disorders and physical conditions, perceived social support and quality of life. Materials and Methods: The World Mental Health Composite International Diagnostic Interview (version 3.0) was administered by trained interviewers to 6126 residents aged ≥18 years old to assess OCD prevalence and that of other select psychiatric disorders. Details on sociodemographics, perceived social support and health-related quality of life were obtained. Results: Lifetimeand 12-month prevalence of OCD was 3.6% and 2.9%, respectively. Adjusted regression analysis showed that those with OCD had significantly higher odds of major depressive disorder (odds ratio [OR], 5.4), bipolar disorder (OR, 8.9), generalised anxiety disorder (OR, 7.3) and alcohol abuse (OR, 2.7). OCD was significantly associated with suicidal ideation and suicidality (OR, 5.1). OCD subjects also had higher odds of chronic pain (OR, 2.4) and diabetes (OR, 3.1). Finally, OCD subjects had lower mean mental composite summary scores than controls (respondents without any of the psychiatric disorders and physical conditions included in SMHS 2016) and those with other lifetime psychiatric disorders and physical conditions. Conclusion: OCD prevalence in Singapore is high. Most people with OCD do not seek treatment despite experiencing significant comorbidity and loss of quality of life. Key words: Composite International Diagnostic Interview, Epidemiology, Multi-ethnic, Psychiatric disorder, Survey

The effects of intradialytic resistance training on muscle strength, psychological well-being, clinical outcomes and circulatory micro-ribonucleic acid profiles in haemodialysis patients: Protocol for a quasi-experimental study

BACKGROUND

Intradialytic resistance training (IRT) protects patients' muscle mass and functions against protein-energy wasting, malnutrition and cachexia. However, the evidence of the effects of such an intervention in haemodialysis patients is limited and not conclusive. To improve the applicability of such interventions, we need a better understanding of molecular, functional and psycho-social adaptation in dialysed patients following a physical training. Therefore, the aim of this study is to investigate the effects of IRT on lower extremity muscle functions, quality of life, and anxiety and depression, clinical outcomes and circulatory micro-ribonucleic acid (miRNA) profiles in patients on chronic haemodialysis therapy.

METHODS

We will perform a quasi-experimental study in 3 dialysis centres. Patients will be recruited via their nephrologists and will be allocated to an experimental and a control group based on the location of the patients' dialysis centre. Patients allocated to the experimental group will undergo a 12-week IRT, while the control group will remain physically inactive during dialysis. The primary outcome is the change in the maximal force produced during an isometric contraction of lower extremity muscles. Secondary outcomes regard quality of life, anxiety and depression, clinical outcomes and circulatory miRNA profiles. Patients' level of health literacy defined as the ability to get and understand health information will be also measured in the study as a potential modifier of effects.

DISCUSSION

This quasi-experimental study can add in an important way to our understanding of the effects of resistance training on dialysis patients' muscle strength, quality of life and disease-specific outcomes.

Psychometric Properties of the Multidimensional Scale of Perceived Social Support in Greek Nurses

BACKGROUND

Psychosocial well-being in the workplace may increase retention of oncology nurses, while a lack of social support has been a predictor of occupational stress in nurses.

PURPOSE

To further explore this phenomenon by examining the psychometric properties of the Multidimensional Scale of Perceived Social Support in Greek nurses working in oncology and mental health settings.

METHODS

A cross-sectional design was used. The sample consisted of 150 nurses (70 oncology nurses and 80 mental health nurses) from the area of greater Athens who joined the study. The scale was translated to Greek using the "forward-backward" procedure. The Multidimensional Scale of Perceived Social Support's internal consistency reliability (Cronbach's α), stability (intraclass correlation coefficient), factor structure (factor analysis), and convergent validity (correlation with Ways of Coping Questionnaire) were examined.

RESULTS

A three-factor (significant others, family, and friends) model was confirmed. The subscales representing the three factors demonstrated excellent internal consistency reliability (Cronbach's αs > .90) and stability intraclass correlation coefficient (>.90).

CONCLUSIONS

The measure is reliable and valid, and it can be used to assess nurses' social support; the results of such an assessment could be helpful when selecting strategies for assisting nurses.

Chinese Drug Users’ Abstinence Intentions: The Role of Perceived Social Support

This study investigated the relationship between Chinese drug users’ perceived social support and their intentions for choosing abstinence. Both bivariate and multivariate analyses were performed with 3,239 drug users, especially heroin (427) and methamphetamine (890) users. All participants were from multiple Chinese compulsory drug treatment institutions. Perceived support from friends was the factor that showed a strongest positive relationship with Chinese drug users’ abstinence intentions. The positive influence from family support on the willingness to seek and choose abstinence was not as great as scholars have suggested, which challenges previous research findings. Methamphetamine users had a significantly lower chance of pursuing abstinence, but their abstinence intentions were positively related to perceived support from friends. Comparatively, all types of perceived social support had no significant influence on heroin users’ abstinence intentions. This study highlights that, as China’s methamphetamine-addicted population rapidly expands, tailored treatment, especially facilitating positive peer support, is urgently needed.

Work out by Walking: A Pilot Exercise Program for Individuals With Schizophrenia Spectrum Disorders

The health benefits of exercise are well documented, yet annual health care costs related to physical inactivity are well within the billions. Furthermore, individuals with schizophrenia spectrum disorders (SSDs) are more likely to lead sedentary lives, exercise less than the general population, and die prematurely from preventable causes. Previous research examining the effects of exercise on individuals with SSDs has been encouraging yet limited in creating accessible and sustainable interventions. The current pilot study developed and evaluated the impact of Work out by Walking (WOW), a multicomponent group walking intervention on the health of 16 individuals with SSDs. Results indicated improvements in indicators of physical health, activity level, social support, and mental health and a high level of program satisfaction. Future research should examine multicomponent group walking programs for individuals with SSDs in larger samples and with the inclusion of a comparison condition.

Reliability and validity of the multidimensional scale of perceived social support in Chinese mainland patients with methadone maintenance treatment

INTRODUCTION

The multidimensional scale of perceived social support (MSPSS) is a valid tool for assessing perceived support from family, friends and significant others. However, evidence about reliability and validity of the MSPSS in Chinese mainland patients with methadone maintenance treatment (MMT) is lacking.

METHODS

The patients (n=1212) being admitted to the first two largest MMT clinics in Xi'an were recruited in the study. Reliability was estimated with Cronbach's α and intra-class correlation (ICC). Convergent and discriminant validity was assessed using item-subscale correlation. Factorial validity was examined using exploratory and confirmatory factor analysis. The patients answered the questions of MSPSS at baseline and re-test after 6months, respectively.

RESULTS

Cronbach's α of the overall MSPSS was 0.92 (subscales range: 0.84-0.89). ICC of the overall MSPSS was 0.65 (subscales range: 0.57-0.64). Better convergent validity (r≥0.40) was demonstrated by the satisfactory hypothesized item-subscale correlation. All of the hypothesized item-subscale correlations were higher than the correlations between the hypothesized items and other subscales, indicating better discriminant validity. Two factors were extracted from the 12 items, with factor 1 mainly covering friends and significant others subscales (explained 55.56% variance) and factor 2 mainly covering family subscale (explained 11.77% variance). In comparison with the proposed three-subscale model, the two-factor observed model did not fit well in this sample according to model fit indices.

CONCLUSIONS

The MSPSS has acceptable reliability and convergent/discriminant validity in Chinese mainland MMT patients. The proposed three-factor model of MSPSS is much better fit than the two-factor observed model in this study. Findings of the study will provide evidence of psychometric properties of the MSPSS in MMT patient population and expand the use of the MSPSS in clinical MMT context.

Identifying correlates of self-stigma in adults who stutter: Further establishing the construct validity of the Self-Stigma of Stuttering Scale (4S)

PURPOSE

This study was set up to further establish the construct validity of the Self-Stigma of Stuttering Scale (4S) by demonstrating its associations with other established scales and replicating its original factor structure and reliability estimates.

METHOD

Web surveys were completed by 354 adults who stutter recruited from Board Certified Specialists in Fluency Disorders, and adult chapters of the National Stuttering Association. Participants completed a series of psychometrically validated scales measuring self-stigma, hope, empowerment, quality of life, social support, anxiety, depression, and self-rated speech disruption.

RESULTS

Higher subscale and total stigma scores on the 4S were associated with significantly lower levels of hope, empowerment, quality of life, and social support, and significantly higher levels of anxiety, depression, and self-rated speech disruption. The original factor structure of the 4S was replicated, and reliability estimates of the subscales ranged from adequate to excellent.

CONCLUSIONS

The findings of this study support the construct validity of the 4S and its use by clinicians and researchers intending to measure the construct of self-stigma in adults who stutter.

EDUCATIONAL OBJECTIVES

Readers should be able to: (a) distinguish between the various components of self-stigma; (b) describe how the various components of the self-stigma model relate to hope, empowerment, quality of life, and social support, self-rated speech disruption, anxiety, and depression; (c) summarize the psychometric properties of the Self-Stigma of Stuttering Scale (4S) in terms of reliability, factor structure, and construct validity; (d) discuss how the 4S could be used in research and clinical practice.

Effectiveness of a peer-led self-management programme for people with schizophrenia: protocol for a randomized controlled trial

AIM

To determine the effectiveness of a peer-led self-management programme for people with schizophrenia in reducing psychotic symptom severity, hospital readmission and psychiatric consultation and in enhancing cognition, empowerment, functioning level, medication adherence, perceived recovery, quality of life and social support.

BACKGROUND

Several self-management programmes have been developed to empower patients with severe mental illness in achieving recovery. Research suggests that peer-led self-management programmes have positive effects on patient recovery. However, the existing evidence is inconclusive, due to a lack of credible evidence and long-term follow-up evaluations.

DESIGN

A stratified randomized controlled trial will be conducted at six community mental health rehabilitation centres

METHODS

A sample of 242 adults with schizophrenia will be recruited. A peer-led self-management programme, comprising six 2-hour sessions, will be implemented in the intervention group and a standard rehabilitation programme in the control group. Outcomes will be measured at baseline, postintervention and at the 6- and 12-month follow-ups. The measures will include cognition, empowerment, functioning level, medication adherence, perceived recovery, quality of life, social support, symptom severity, hospital readmission and psychiatric consultation. A mixed effects model will be used to analyse the results. Semi-structured interviews will be conducted to explore the peer-trainers' and participants' perspectives on the programme. Research Ethics Committee approval was obtained in December 2011 and funding was obtained in January 2012.

CONCLUSION

This study will provide evidence on the effectiveness of a peer-led self-management programme for patient recovery. It will identify a clinically useful and potentially effective intervention that incorporates empowerment concept.

Social support, depression, and physical disability: age and diagnostic group effects

BACKGROUND

Social support is an important resource that may benefit individuals aging with physical disabilities, although its effects may vary depending on age, sex, and type of disability.

OBJECTIVES

To (1) examine differences in social support--and how support might vary as a function of age and sex--in samples of individuals with multiple sclerosis (MS), spinal cord injury (SCI), and muscular dystrophy (MD) and (2) understand the extent that associations between different support domains and depression might be moderated by disability diagnosis, sex and age.

METHODS

A convenience sample (N = 1416) of individuals with MS, SCI, and MD completed surveys that included measures of perceived social support and depressive symptoms.

RESULTS

No significant support differences were found between diagnostic groups. There was a gradual decrease in social support with chronological age, and women reported more support than men, particularly friend support. Levels of perceived friend support were negatively associated with depression, and the associations between social support and depression did not differ as a function of age, sex, or diagnosis.

CONCLUSIONS

Social support is similarly associated with lower levels of depression for men and women, across disability diagnoses and all ages. Being a man and being older may be associated with lower levels of perceived support. Research is needed to determine if interventions that improve support will decrease depression and improve quality of life in persons with disabilities, particularly for men and individuals who are aging.

The Swedish version of the multidimensional scale of perceived social support (MSPSS)--a psychometric evaluation study in women with hirsutism and nursing students

Background

The Multidimensional Scale of Perceived Social Support (MSPSS) is a short instrument, developed to assess perceived social support. The original English version has been widely used. The original scale has demonstrated satisfactory psychometric properties in different settings, but no validated Swedish version has been available. The aim was therefore to translate, adapt and psychometrically evaluate the Multidimensional Scale of Perceived Social Support for use in a Swedish context.

Method

In total 281 participants accepted to join the study, a main sample of 127 women with hirsutism and a reference sample of 154 nursing students. The MSPSS was translated and culturally adapted according to the rigorous official process approved by WHO. The psychometric evaluation included item analysis, evaluation of factor structure, known-group validity, internal consistency and reproducibility.

Results

The original three-factor structure was reproduced in the main sample of women with hirsutism. An equivalent factor structure was demonstrated in a cross-validation, based on the reference sample of nursing students. Known-group validity was supported and internal consistency was good for all scales (α = 0.91-0.95). The test-retest showed acceptable to very good reproducibility for the items (κ_w = 0.58-0.85) and the scales (ICC = 0.89-0.92; CCC = 0.89-0.92).

Conclusion

The Swedish version of the MSPSS is a multidimensional scale with sound psychometric properties in the present study sample. The simple and short format makes it a useful tool for measuring perceived social support.

Long- and short-term inpatients with schizophrenia in China: implications for community-based service development

INTRODUCTION

There is an increasing interest in the patterns of mental health care of people with serious mental illnesses in China, where outpatient and community-based care are not fully developed and long-term hospitalization is still not uncommon. Comparison of sociodemographic and clinical characteristics of long-term and short-term inpatients diagnosed with schizophrenia can be informative about pattern of treatment and their relationship to services needs.

METHODS

Seventy-three long-term schizophrenia inpatients (current length of stay of more than 5 years) were compared to 116 short-term schizophrenia inpatients (current length of stay of 30 days or less) assessed with the Individual Background Questionnaire, the Positive and Negative Syndrome Scale (PANSS) and the Social Support Rating Scale (SSRS).

RESULTS

There was no significant difference between the groups on the total PANSS symptom score but the short-term inpatients scored significantly higher than their long-term counterparts on the Positive Syndrome sub-scale and the SSRS and lower on the Negative Syndrome sub-scale.

DISCUSSION

Differences in symptomatology and social functioning may be related to better medication adherence and more extended social isolation among long-term inpatients while the increased positive symptoms are likely to reflect more acute disease process in short-term inpatients, and possibly poorer medication adherence. These differences may be especially pronounced in developing countries like China in which community-based services need to be more fully developed to facilitate medication adherence and prevent relapse, and to support community adjustment of socially isolated patients who otherwise require hospitalization.

A revised Thai Multi-Dimensional Scale of Perceived Social Support

In order to ensure the construct validity of the three-factor model of the Multi-dimensional Scale of Perceived Social Support (MSPSS), and based on the assumption that it helps users differentiate between sources of social support, in this study a revised version was created and tested. The aim was to compare the level of model fit of the original version of the MSPSS against the revised version--which contains a minor change from the original. The study was conducted on 486 medical students who completed the original and revised versions of the MSPSS, as well as the Rosenberg Self-Esteem Scale (Rosenberg, 1965) and Beck Depression Inventory II (Beck, Steer, & Brown, 1996). Confirmatory factor analysis was performed to compare the results, showing that the revised version of MSPSS demonstrated a good internal consistency--with a Cronbach's alpha of .92 for the MSPSS questionnaire, and a significant correlation with the other scales, as predicted. The revised version provided better internal consistency, increasing the Cronbach's alpha for the Significant Others sub-scale from 0.86 to 0.92. Confirmatory factor analysis revealed an acceptable model fit: chi2 128.11, df 51, p < .001; TLI 0.94; CFI 0.95; GFI 0.90; PNFI 0.71; AGFI 0.85; RMSEA 0.093 (0.073-0.113) and SRMR 0.042, which is better than the original version. The tendency of the new version was to display a better level of fit with a larger sample size. The limitations of the study are discussed, as well as recommendations for further study.
