Scholars have consistently documented the relationship between conformity to traditional masculine norms and maladaptive psychosocial outcomes among boys and young men. Given current social commentary, including debate around 'toxic masculinity', intervention is needed to encourage boys to embody healthy expressions and identities of masculinity. Whilst new approaches grounded in positive masculinity show promise, the construct requires further definition and phenomenological clarity. Here we review divergent perspectives on positive masculinity, and forward a refined definition, specific to psychosocial health promotion among boys and young men. We then outline the theoretical basis of a positive masculinity framework to guide the content of future interventions, aiming to achieve positive identity development among boys and young men for the good of all. This framework represents a necessary unification of scholarship around male adolescent development, education and health. Future health promotion interventions may benefit from applying the framework to support a positive psychosocial trajectory among boys and young men, with a focus on connection, motivation and authenticity.
