OBJECTIVES: The aim of this rapid scoping review was to provide a summary of the available evidence on the development and implementation of peer support work in mental health services. The specific objectives were: to undertake a comprehensive review of the literature on peer support work; and identify how such work may be best implemented.

METHODS: A rapid scoping review was identified as the most appropriate approach to reviewing the literature mainly because the objectives of this review were relatively broad and there was a short timeframe. In a rapid scoping review the data extraction and reporting are focused and limited to provide an overview of existing evidence.

RESULTS: From the initial database results of 7406 records, 663 were identified as meeting the inclusion criteria. The most relevant of these were then selected ( = 26) to be reported in this review with existing reviews of the research evidence ( = 7) being prioritised. The findings were organised into a number of sections: definitions, values and the role; development and implementation of peer support work; experiences of peer support workers; perceptions of others about peer support work; recruitment of peer support workers; training; supervision and support; and research on effectiveness.

CONCLUSIONS: There are excellent sources of guidance, considerable qualitative research about experiences and some encouraging, but limited, findings about the impact of peer support work specifically on recovery-oriented outcomes. There is a need for further rigorous research on the key aspects and effectiveness of peer support work.
