The benefits of peer support interventions (PSIs) for individuals with mental illness are not well known. The aim of this systematic review and meta-analysis was to assess the effectiveness of PSIs for individuals with mental illness for clinical, personal, and functional recovery outcomes.
Searches were conducted in PubMed, Embase, and PsycINFO (December 18, 2020). Included were randomized controlled trials (RCTs) comparing peer-delivered PSIs to control conditions. The quality of records was assessed using the Cochrane Collaboration Risk of Bias tool. Data were pooled for each outcome, using random-effects models.
After screening 3455 records, 30 RCTs were included in the systematic review and 28 were meta-analyzed (4152 individuals). Compared to control conditions, peer support was associated with small but significant post-test effect sizes for , = 0.19, 95% CI (0.11-0.27), = 10%, 95% CI (0-44), and = 0.15, 95% CI (0.04-0.27), = 43%, 95% CI (1-67), but not for , = 0.08, 95% CI (-0.02 to 0.18), = 36%, 95% CI (0-61). Our findings should be considered with caution due to the modest quality of the included studies.
PSIs may be effective for the clinical and personal recovery of mental illness. Effects are modest, though consistent, suggesting potential efficacy for PSI across a wide range of mental disorders and intervention types.
同伴支持干预（PSIs）对精神疾病患者的益处尚不清楚。本系统评价和荟萃分析的目的是评估 PSIs 对精神疾病患者在临床、个人和功能恢复结果方面的有效性。
在 PubMed、Embase 和 PsycINFO（2020 年 12 月 18 日）中进行了检索。纳入了比较同伴提供的 PSIs 与对照条件的随机对照试验（RCTs）。使用 Cochrane 协作风险偏倚工具评估记录的质量。使用随机效应模型对每个结果进行汇总数据。
在筛选了 3455 条记录后，30 项 RCT 被纳入系统评价，28 项进行了荟萃分析（4152 人）。与对照条件相比，同伴支持与较小但显著的后测效应量相关， = 0.19，95%CI（0.11-0.27）， = 10%，95%CI（0-44）， = 0.15，95%CI（0.04-0.27）， = 43%，95%CI（1-67），但对 = 0.08，95%CI（-0.02-0.18）， = 36%，95%CI（0-61）则不然。由于纳入研究的质量较低，我们的发现应谨慎考虑。
PSIs 可能对精神疾病的临床和个人康复有效。虽然效果较小，但一致表明 PSI 对广泛的精神障碍和干预类型具有潜在疗效。
