Objectives:
To test the primary hypothesis that the PASIM program can produce significantly greater improvements than psychoeducation and/or usual-care only groups at 1-week, 9-month, and/or 18-month follow-ups on patients' functioning; To test the hypothesis that the PASIM program will produce significantly greater improvements than psychoeducation and usual-care-only over the 18-month follow-ups in patients' psychotic symptoms, problem-solving, illness insight, rehospitalization rates, and/or service satisfaction (secondary outcomes); To explore the strengths, weaknesses and areas for improvements of and satisfaction with the PASIM program, from participants' and peer facilitators' perspectives, using individual semi-structured interviews.
Design: A multi-center randomized controlled trial with repeated measures, 3-arm design will be conducted with both outcome and process evaluation.
Subjects: 186 adults with recent-onset psychosis and randomly assigned into three study groups.
Data collection procedure: After explaining the study and ethical issues to participants, written consent and then baseline measurement will be obtained. During interventions, participants' attendance, workbook completion and attritions will be monitored. At 1-week (Posttest-1), and 9- (Posttest-2) and 18-month (Posttest-3) post-intervention, outcome measurements will be evaluated. In addition, individual semi-structured interviews will be conducted after Posttest-1.
Data analysis: Generalized Estimating Equation test will be used to compare mean-value changes in individual outcomes, and Kaplan-Meier survival-analysis used to analyze the relative risks of re-hospitalizations, between groups over follow-ups. Content analysis will be conducted for qualitative interview data.
Expected results: The PASIM is the first peer-supported self-help for illness management intervention for early-stage psychosis, particularly in Chinese population. It can be a useful and potential cost-saving intervention in community mental healthcare service, providing accessible, self-learned illness self-management training facilitated by peer-support workers (persons recovered from psychosis) in views of limited healthcare resources and mental health professionals in locally and internationally.
