A variety of peer worker roles are being introduced into the mental health workforce in England, in a range of organisational contexts and service delivery settings. The evidence base demonstrating the effectiveness of peer worker-based interventions is inconclusive and largely from outside England. This study aimed to test the international evidence base, and what is known generally about role adoption in public services, in a range of mental health services in England. It also aimed to develop organisational learning supporting the introduction of peer worker roles, identifying learning that was generic across mental health services and that which was specific to organisational contexts or service delivery settings.
