Background: Mental health services are currently experiencing much systemic and organisational change. Many countries have adopted a recovery approach to service provision through the development of national policies and frameworks. Within an Irish context, co-production has been identified as one of the four pillars required for services to become recovery orientated. However, there is a paucity of literature relating to the concept within child and adolescent mental health services. This paper aims to synthesise the peer-reviewed evidence on co-production within such services. Methods: A PRISMA compliant systematic review was undertaken. This includes how the reviewer retrieved, shortlisted, and selected studies for inclusion in the review. It outlines the inclusion/exclusion criteria and how these were further developed through the PICO framework. Finally, the methods also outline how the reviewer assessed bias and quality, as well as the process of data synthesis. Results: Two studies were included in this review, both focusing on co-production, but in different contexts within child and adolescent mental health. Two themes were identified: ‘road less travelled’ and ‘co-producing equality’. These themes and the associated sub-themes describe how co-production works in these services. Discussion: These results highlight the paucity of quality literature in co-production within child and adolescent mental health. Both studies scored poorly in terms of quality. Resulting from this review, a number of actions relating to the therapeutic environment need to be taken into account for co-production to be further implemented. Other: The reviewer has not received any funding for this paper. A protocol was not created or registered for this review.
