The effectiveness of peer support on self-efficacy and quality of life in adults with type 2 diabetes: A systematic review and meta-analysis.

Peer support intervention did not lead to better effects on the improvement in self-efficacy and quality of life among adults with type 2 diabetes. However, peer support with intervention duration not more than 6 months had positive effects on self-efficacy and quality of life. More high-quality studies with large sample size are needed to support or counter the results.
