Abstract
AIMS: To assess the effect of peer support intervention on diabetes distress in people with type 2 diabetes. BACKGROUND: Diabetes distress may be decreased by peer support intervention, but findings about the effect of peer support on diabetes distress have been mixed. DESIGN: A systematic review and meta-analysis of randomized controlled studies. DATA SOURCES: PubMed, Embase, CENTRAL, PsycINFO, Web of Science, and CINAHL databases were searched for randomized controlled trials from inception to 30 June 2018. REVIEW METHODS: Investigators assessed eligibility, extracted data, and assessed methodological quality. Standardized mean difference and 95% confidence intervals were calculated for pooled effect size. RESULTS: A total of 13 studies included in systematic review and 10 in meta-analysis. In the random-effects model, the pooled effect size showed current peer support intervention did not significantly reduce diabetes distress in type 2 diabetes population compared with usual care. CONCLUSION: High quality and well-designed studies targeting at reducing diabetes distress are needed to further test the effect of peer support intervention on diabetes distress.
