Effects of a Peer-facilitated, Acceptance-based Self-learning for Illness Management (PASIM) Program

Evaluating the Effects of a Peer-facilitated, Acceptance-based Self-learning for Illness Management (PASIM) Program for Adults With Recent-onset Psychosis: A Randomized Controlled Trial

Psychosis is a very disabling mental illness with a wide range of dysregulations and disruptions in cognition, emotions, and behaviors, resulting in poor functioning and frequent relapses, especially in the first five years of the illness. There is a knowledge gap about whether Peer-facilitated, Acceptance-based Self-learning for Illness Management (PASIM) can have longer-term and more significant benefits than current professional-led psychoeducation in diverse health outcomes of these psychotic patients such as functioning, problem-solving, and recovery. This multi-center randomized controlled trial with repeated measures, 3-arm design is proposed to test and compare the effects between two alternative interventions (PASIM and Psychoeducation Group program) and a usual-care-only group over an 18-month follow-up.

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.
