This article explores how men can be effectively supported to intervene as prosocial bystanders in incidents of sexual harassment within South Wales’ nighttime economy. Using interviews and focus groups with men aged 18–54, the research developed five behavioural “personas” that capture the diverse psychological perspectives influencing decisions to step in.
Through the COM-B model, the study identifies common barriers—particularly limited knowledge of safe intervention techniques and uncertainty around legal implications—as well as important motivational and contextual factors. The persona-based approach demonstrates that men cannot be treated as a single audience; instead, tailored strategies are needed to meet different support needs.
