Abstract

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.
