Positive psychotherapy for psychosis in Hong Kong: A randomized controlled trial.

Recovery-oriented practice has been advocated in mental health services in Hong Kong since 2009. Well-being has become an important area of focus for mental health services. Positive Psychotherapy for Psychosis (PPP) is a well-being-focused intervention for use in psychosis, with preliminary evidence from a randomized controlled trial in the United Kingdom of impact on well-being and symptomatology. The aim of this study was to test the effectiveness of PPP on the well-being of people with psychosis in Hong Kong. The study was a randomized controlled trial with two-arm parallel groups. Both groups received treatments as usual, and in addition the intervention group received a 13-session intervention based on a Cantonese Chinese translation of the PPP manual. Intention-to-treat analysis was used. The trial was registered (ANZCTR: ACTRN12620000464965). A total of 154 participants (78 intervention, 76 control) were recruited. As compared to control group, intervention group participants showed significant changes over time on the primary outcome of well-being assessed using the Chinese Short Warwick-Edinburgh Mental Well-being Scale (p = 0.001) and on secondary outcomes of hope (Agency subscale: p = 0.029) and self-efficacy (p = 0.001). Positive Psychotherapy for Psychosis was found to be an effective treatment in improving the well-being and other mental health outcomes for people with psychosis. It can be recommended for use in mental health services to promote recovery.

Psychometric properties and correlates of Chinese version of Perceived Stress Scale (CPSS-10) in people with common mental disorders with different employment Statuses.

BACKGROUND/OBJECTIVES: Several studies have indicated that stress is associated with common mental disorders, and work stress trebles the risk of developing them. However, a validated assessment tool for measuring and establishing psychological stress correlates in this group of clients remains unavailable. The objectives of the present study were to examine the psychometric properties of the Chinese version of the Perceived Stress Scale-10 (CPSS-10) on people with common mental disorders with different employment statuses and explore its correlates. METHODS: Two hundred and fifty-two participants with common mental disorders were recruited. The data were analysed through exploratory factor and confirmatory analyses to investigate construct validity. The convergent and discriminant validities were examined based on their correlation with other measures, while the internal consistency was estimated using Cronbach's α coefficient. A t-test was used to detect differences between groups. The CPSS-10 correlates were explored using multiple linear regression analysis. RESULTS: Principal component analysis with varimax rotation yielded two factors, which accounted for 63.82% of the total variance, while confirmatory factor analysis confirmed its factor structure. The CPSS-10 had a positively moderate to strong correlation with other measures, thereby indicating its acceptable convergent and discriminant validities. The internal consistency ranged from acceptable to good for the two subscales and ten overall items, while the item-total correlation was adequate except for the seventh item. There were no group differences in gender nor employment status. Finally, the CPSS-10 predictors were studied. CONCLUSION: The CPSS-10 is a reliable and valid instrument for people with common mental disorders with different employment statuses.

Chinese version of the Recovery Self-Assessment scale: psychometric evidence from Rasch analysis and reliability estimates.

BACKGROUND: The Recovery Self-Assessment (RSA) is a popular and well-validated instrument for assessing recovery-oriented service around the world. AIMS: This study aims to develop a Chinese version of the RSA, which assesses the recovery orientation of hospital-based mental health services. METHODS: We conducted forward and backward translations of the RSA and modify the translated Chinese based on comments by content experts. We recruited 350 people with mental illnesses who regularly attend hospital and community mental health services. The participants completed the Chinese Recovery Self-Assessment Service User version (CRSA-SU) and convergent measures on hope and mental well-being. RESULTS: The Rasch analysis supported five of the six factors in the instrument and suggests that the "Life Goal" factor could be further split into two factors. We identified three misfit items (items 6, 12 and 17) that could be considered for removal. Both the internal consistency and test-retest reliability are between satisfactory and very good within each subscale, with the exception of the Choice subscale. The seven subscales had low positive correlations with measures of hope and mental well-being, which supported the convergent validity of CRSA-SU. CONCLUSIONS: The results supported the factor structure, reliability and validity of the CRSA-SU.
