PROTOCOL: Arts‐based interventions for offenders in secure criminal justice settings to improve rehabilitation outcomes: An evidence and gap map

This is the protocol for a Campbell review. The objective of this evidence and gap map is to presents the existing research on the impact of arts‐based interventions in secure criminal justice settings (SCJS) that aim to improve desistance outcomes for offenders. It will indicate the quality of available evidence, highlighting the gaps and informing future research priorities. Importantly, it will also identify where the evidence could be systematically reviewed. This would clearly produce a more comprehensive understanding of the available knowledge and an opportunity to move forward in a more direct and focussed way, with the potential to influence research, intervention development, and inform funding decisions.
