The relationships of change in work climate with changes in burnout and depression: a 2-year longitudinal study of Chinese mental health care workers.

Mental health care workers face heavy emotional demand and are prone to work burnout. Work burnout has been associated with poor mental health and work climate, which refers to individual perceptions about work setting. The purpose of this study was to examine whether intra-individual changes in work climate were associated with intra-individual changes in burnout and depression over two years. The present sample included Chinese mental health care workers (N = 312; mean age = 38.6, SD = 9.9) working in a psychosocial rehabilitation institution. The participants completed questionnaires on work climate, work burnout and depression at seven time points across two years. Parallel process latent growth modeling was used to analyze the associations of change between work climate and burnout and depression. Work climate displayed a logarithmic decreasing trend while burnout and depression displayed logarithmic increasing trends over two years. Baseline levels of work climate were negatively and moderately associated with baseline levels of burnout and depression (r = -.44 to -.60, p < .01). Changes in work climate were negatively and moderately associated with change in burnout (r = -.43, p < .01) and change in depression (r = -.31, p < .05). Change in burnout was positively and strongly associated (r = .58, p < .01) with change in depression. The current results support temporal relationships among changes in work climate, burnout and depression across time. Practical implications for future preventive work in burnout interventions were discussed within this population.

Psychometric validation of the consensus five-factor model of the Positive and Negative Syndrome Scale.

BACKGROUND: The Positive and Negative Syndrome Scale (PANSS) is widely used for clinical assessment of symptoms in schizophrenia. Instead of the traditional pyramidal model, recent literature supports the pentagonal model for the dimensionality of the PANSS. AIM: The present study aimed to validate the consensus five-factor model of the PANSS and evaluate its convergent validity. METHODS: Participants were 146 Chinese chronic schizophrenic patients who completed diagnostic interviews and cognitive assessments. Exploratory structural equation modeling (ESEM) was performed to investigate the dimensionality of the PANSS. Covariates (age, sex, and education level) and concurrent outcomes (perceived stress, memory, daily living functions, and motor deficits) were added in the ESEM model. RESULTS: The results supported the consensus 5-factor underlying structure, which comprised 20 items categorized into positive, negative, excitement, depression, and cognitive factors with acceptable reliability (α=.69-.85) and strong factor loadings (λ=.41-.93). The five factors, especially the cognitive factor, showed evident convergent validity with the covariates and concurrent outcomes. CONCLUSION: The results support the consensus five-factor structure of the PANSS as a robust measure of symptoms in schizophrenia. Future studies could explore the clinical and practical utility of the consensus five-factor model.

Psychometric properties of a Chinese version of the Stigma Scale: examining the complex experience of stigma and its relationship with self-esteem and depression among people living with mental illness in Hong Kong.

BACKGROUND: Stigma of mental illness is a global public health concern, but there lacks a standardized and cross-culturally validated instrument for assessing the complex experience of stigma among people living with mental illness (PLMI) in the Chinese context. AIM: This study examines the psychometric properties of a Chinese version of the Stigma Scale (CSS), and explores the relationships between stigma, self-esteem and depression. METHODS: A cross-sectional survey was conducted with a community sample of 114 Chinese PLMI in Hong Kong. Participants completed the CSS, the Chinese Self-Stigma of Mental Illness Scale, the Chinese Rosenberg Self-Esteem Scale, and the Chinese Patient Health Questionnaire-9. An exploratory factor analysis was conducted to identify the underlying factors of the CSS; concurrent validity assessment was performed via correlation analysis. RESULTS: The original 28-item three-factor structure of the Stigma Scale was found to be a poor fit to the data, whereas a revised 14-item three-factor model provided a good fit with all 14 items loaded significantly onto the original factors: discrimination, disclosure and positive aspects of mental illness. The revised model also displayed moderate to good internal consistency and good construct validity. Further findings revealed that the total stigma scale score and all three of its subscale scores correlated negatively with self-esteem; but only total stigma, discrimination and disclosure correlated positively with depression. CONCLUSION: The CSS is a short and user-friendly self-administrated questionnaire that proves valuable for understanding the multifaceted stigma experiences among PLMI as well as their impact on psychiatric recovery and community integration in Chinese communities.

Tai-chi for residential patients with schizophrenia on movement coordination, negative symptoms, and functioning: a pilot randomized controlled trial.

Objective. Patients with schizophrenia residing at institutions often suffer from negative symptoms, motor, and functional impairments more severe than their noninstitutionalized counterparts. Tai-chi emphasizes body relaxation, alertness, and movement coordination with benefits to balance, focus, and stress relief. This pilot study explored the efficacy of Tai-chi on movement coordination, negative symptoms, and functioning disabilities towards schizophrenia. Methods. A randomized waitlist control design was adopted, where participants were randomized to receive either the 6-week Tai-chi program and standard residential care or only the latter. 30 Chinese patients with schizophrenia were recruited from a rehabilitation residency. All were assessed on movement coordination, negative symptoms, and functional disabilities at baseline, following intervention and 6 weeks after intervention. Results. Tai-chi buffered from deteriorations in movement coordination and interpersonal functioning, the latter with sustained effectiveness 6 weeks after the class was ended. Controls showed marked deteriorations in those areas. The Tai-chi group also experienced fewer disruptions to life activities at the 6-week maintenance. There was no significant improvement in negative symptoms after Tai-chi. Conclusions. This study demonstrated encouraging benefits of Tai-chi in preventing deteriorations in movement coordination and interpersonal functioning for residential patients with schizophrenia. The ease of implementation facilitates promotion at institutional psychiatric services.

Validation of the Chinese version of Underwood's Daily Spiritual Experience Scale--transcending cultural boundaries?

BACKGROUND: Daily spiritual experience (DSE) refers to one's interaction with the transcendent in day-to-day life. Underwood's Daily Spiritual Experience Scale mic(DSES) was developed to measure this experiential component of religiousness and spirituality. Addressing ordinary daily experiences rather than particular beliefs, DSES has transcultural applicability potential. PURPOSE: The current study aimed to develop and evaluate the Chinese version of DSES (DSES-C). METHOD: The 16-item scale was translated faithfully through standard translation/back-translation procedures. The term "God" required an extended definition embracing both a humanized and a philosophical higher power in Chinese culture. The translated scale plus a battery of validation scales were administered to staff of a large rehabilitation service complex, resulting in 245 completed questionnaires. RESULTS: Exploratory factor analysis revealed a similar factor structure as the original English version and similar problems with items 13 (compassion) and 14 (mercy). After carefully deliberating on the Chinese conceptualization of spirituality and balancing psychometric properties, the one-factor 16-item structure of the English version was supported. DSES-C showed high internal consistency (Cronbach's alpha = 0.97). Construct validity was supported by correlations with validation scales in expected directions. CONCLUSION: The psychometric properties of DSES were similar to the English version in factor structure, internal consistency, and convergence/divergence construct validity.

Psychiatric symptoms mediate the effects of neurological soft signs on functional outcomes in patients with chronic schizophrenia: A longitudinal path-analytic study.

Neurological soft signs (NSS) in motor coordination and sequencing occur in schizophrenia patients and are an intrinsic sign of the underlying neural dysfunctions. The present longitudinal study explored the relationships among NSS, psychiatric symptoms, and functional outcomes in 151 Chinese patients with chronic schizophrenia across a 6-month period. The participants completed neurological assessments at baseline (Time 1), psychiatric interviews at Time 1 and 3-month follow-up (Time 2), and self-report measures on daily functioning at 6-month follow-up (Time 3). Two possible (combined and cascading) path models were examined on predicting the functional outcomes. Direct and indirect effects of Time 1 NSS on Time 3 functional outcomes via Time 2 psychiatric symptoms were evaluated using path analysis under bootstrapping. Motor coordination and sequencing NSS did not have significant direct effects on functional outcomes. Motor coordination NSS exerted significant and negative indirect effects on functional outcomes via psychiatric symptoms. These results contribute to a better understanding of the determinants of functional outcomes by showing significant indirect pathways from motor coordination NSS to functional outcomes via psychiatric symptoms. That motor sequencing NSS did not affect functional outcomes either directly or indirectly may be explained by their trait marking features.

Associations between diurnal cortisol patterns and lifestyle factors, psychotic symptoms, and neurological deficits: A longitudinal study on patients with chronic schizophrenia.

The present study examined the relationships between diurnal cortisol patterns and perceived stress, lifestyle factors, psychotic symptoms, neurological deficits, and daily functioning in patients with chronic schizophrenia. The participants were 149 Chinese patients with chronic schizophrenia, who provided salivary cortisol measures upon waking, before lunchtime, and before bedtime at baseline (Time 1). Self-report measures on perceived stress and lifestyle factors such as body-mass index and daily exercise span were recorded at Time 1. Diagnostic assessments on psychotic symptoms, neurological deficits, and daily functioning were made at Time 1 and Time 2 (3 months later). Latent growth modeling and path modeling analysis were performed to investigate the diurnal cortisol patterns and the relationships with the study variables, respectively. Greater perceived stress and body-mass index and less physical activity were significantly linked to reduced cortisol decline. Reduced cortisol decline at Time 1 significantly predicted greater psychotic (positive and negative) symptoms and more severe neurological deficits in motor coordination and sequencing of complex motor acts at Time 2. The present results contribute to a better understanding of the diurnal cortisol patterns among chronic schizophrenia patients and the associations with lifestyle factors, psychotic symptoms, and neurological deficits. The findings lend support to the neural diathesis-stress model and suggest that hypothalamic-pituitary-adrenal axis may potentially mediate the effects of lifestyle factors on psychotic symptoms and neurological deficits.

A randomized controlled trial on the psychophysiological effects of physical exercise and Tai-chi in patients with chronic schizophrenia.

The chronic and prevalent natures of schizophrenia result in long-term institutionalization for the patients. Conventional treatment of anti-psychotic medication on management of psychotic symptoms often brings on severe side effects and reduces patients' well-being. Tai-chi is a mind-body exercise that underscores motor coordination and relaxation. This 3-arm randomized controlled trial investigated the psychophysiological benefits of Tai-chi on 153 chronic schizophrenia patients, who were recruited from a mental health rehab complex and randomized into Tai-chi, exercise, or waitlist control groups. Both intervention groups received 12weeks of specific intervention plus standard medication received by the controls. All participants completed psychiatric interviews, self-report questionnaires, performance tasks, and salivary cortisol measures at baseline, 3-month, and 6-month follow-up on psychotic symptoms, motor coordination, memory, daily living function, and stress. Multigroup latent growth modeling was used to evaluate the intervention effects on the outcomes. Compared to controls, the Tai-chi group showed significant decreases in motor deficits and increases in backward digit span and mean cortisol, while the exercise group displayed significant decreases in motor deficits, negative and depression symptoms and increases in forward digit span, daily living function, and mean cortisol. The two interventions did not show significantly different therapeutic effects, except for fewer symptom manifestations in the exercise group. These results suggest psychophysiological benefits for Tai-chi on chronic schizophrenia patients in terms of motor coordination and memory. Though both Tai-chi and exercise groups tended to manifest fewer symptoms than the control group, the exercise group showed better symptoms management than the Tai-chi group.
