Practitioner Review: Effectiveness and mechanisms of change in participatory arts-based programmes for promoting youth mental health and well-being - a systematic review.

There is good evidence that there are therapeutic processes in PAB programmes. There is a need for more transdisciplinary work to increase understanding of context-mechanism-outcome pathways, including the role played by different art stimuli and practices. Going forward, transdisciplinary teams are needed to quantify short- and long-term mental health and well-being outcomes and to investigate optimal programme durations in relation to population and need. Such teams would also be best placed to work on resolving inter-disciplinary methodological tensions.
