AbstractThis systematic review aimed to identify interventional studies regarding peer-delivered interventions for people with severe mental illness and synthesize the evidence of the effects and characteristics of these studies.
A systematic search was conducted with eight research databases (including Scopus, PsycINFO, MEDLINE, CINAHL, Web of Science, EMBASE, Cochrane Central Register of Controlled Trials, and China Academic Journals Full-text Database). Key search terms included: “peer or user or consumer” AND “delivered or led or run or managed” AND “‘severe mental illness *’ or ‘serious mental illness*’ or ‘schizophrenia’ or ‘schizoaffective disorder’ or ‘psychotic’ or ‘bipolar disorder' or ‘major depression’”. Randomised controlled trials that evaluated the effectiveness of peer-delivered interventions for people with severe mental illness were identified. Interventional studies that focused on peer/mutual support were excluded. The outcome of interests included participants’ clinical and psychosocial outcomes. Reference lists of the identified articles were reviewed to find additional relevant articles.
A total of twelve studies including 2707 participants were included in the review, with the majority of the studies conducted in developed countries. Findings showed equivalent effects between the interventions delivered by peers and health professions on clinical outcomes (i.e., changes in psychiatric symptoms). Moreover, significant positive effects were achieved for psychosocial outcomes (e.g., self-efficacy, hopefulness and quality of life) in the peer-delivered intervention group, when compared with interventions delivered by health professionals or treatment as usual. Due to the heterogeneity of different intervention approaches used in the article, findings were synthesized narratively without conducting a meta-analysis.
