Purpose--This paper aims to explore the role of drama and theatre in promoting the emotional and social wellbeing of a group of young Black men living in south London. Design/methodology/approach--A qualitative methodology was used in a process and outcome evaluation of a drama-based initiative that aimed to promote young Black men's sexual and emotional health. Findings--The research found that this community-based initiative was able to promote young people's self-esteem and a positive sense of agency. This was achieved by creating opportunities for self-expression, reflection and self-understanding, and through the development of relationships between participants characterised by trust and reciprocity. Originality/value--The evaluation points to the strengths of youth and community work and arts-based approaches in engaging young people around health issues and in promoting emotional wellbeing and a positive sense of identity among young people. The evaluation also highlights the usefulness of process-oriented qualitative evaluation as an appropriate way of evaluating and contributing to the ongoing development of initiatives that aim to use the arts in healthcare settings.
