Recognition has grown that peer support workers serve an important role in facilitating decision making about treatment and recovery among people with mental health conditions. This article provides examples of peer-facilitated decision support interventions in the literature, discusses promises and potential pitfalls associated with peers serving in decision support roles, and offers recommendations for research and practice. Examples were selected from the literature on decision support interventions for people with serious mental illnesses, such as schizophrenia, bipolar disorder, and major depression. Promises, pitfalls, and recommendations were informed by this research and by the literature on lived experience perspectives, the helper-therapy principle, and reported barriers to and facilitators of peers assisting with decision making. According to the included studies, peers may facilitate decision making in several ways (e.g., by asking service users about their goals or preferences, assisting them with using decision support tools, sharing stories, and facilitating access to information and resources). Peer-facilitated decision support may be associated with positive decision making and health outcomes for service users and peer support workers. However, providers need to carefully consider barriers to implementation of this support, such as inadequate resourcing, poor integration, and compromising of peer support values.
