ABSTRACT
OBJECTIVE: Peer support workers are a substantial and growing part of the mental health workforce. Because little research has investigated how to effectively support and supervise peer support workers, the authors evaluated the efficacy of a training program to strengthen the peer support workforce and the supervision of its workers. METHODS: Mental health services sites with peer support workers and supervisors in Los Angeles County were recruited for this cluster-randomized trial and 10-month follow-up. Of 348 peer support workers and 143 supervisors at 85 sites, 251 (72%) peer support workers and 115 (80%) supervisors completed baseline surveys. SHARE! the Self-Help And Recovery Exchange, a peer-run organization, delivered four training sessions on strategies to reduce stigma and to build an effective peer workforce, cultural competence, and a trauma-informed developmental model of supervision. Primary outcomes were peer-supportive organizational climate, mental health stigma, and peer support worker recovery. RESULTS: Intention-to-treat analyses indicated that sites receiving the training had significantly higher scores on peer-supportive organizational climate (Cohen's d=0.35, 95% CI=0.02-0.68, p=0.04) relative to sites not receiving the training. No significant differences were found between the two conditions for mental health stigma (Cohen's d=0.04) or peer support worker recovery (Cohen's d=0.14). CONCLUSIONS: The training had no impact on mental health stigma or peer support worker recovery. However, the findings suggest that the training increased the value organizations gave to peer support work, which may help improve peer support worker retention and outcomes among those served. Efforts to incorporate principles of the training into practice may strengthen outcomes.
