Primary prevention programs targeting boys and young men at risk of using violence operate in a space where the evidence base is still developing, and knowing what works, for whom, and in what circumstances, is far from settled.

This presentation draws on 3 years of developmental evaluation of a primary prevention pilot to share three interconnected findings at the intersection of evaluation practice and implementation science.

First, we present evidence that participant and program alignment is among the most influential contextual factors shaping outcomes – a finding with direct implications for how programs like this should be targeted and resourced.

Second, we discuss how a significant program design shift, from targeting harmful gender norms directly to exploring participants' own values as an entry point, improved engagement and created the conditions for more meaningful reflection on masculinity and behaviour.

Third, we explore the adaptation dilemma: when evaluation signals resistance from participants, how should program designers respond?

Drawing on findings across multiple pilot phases, we discuss the tension between adapting to improve engagement and holding firm on program fidelity when discomfort is itself part of the change process. We close by examining what these findings mean for how evaluators interpret and communicate success in primary prevention settings, where uniform outcomes are neither expected nor realistic, and where the most meaningful impacts may be concentrated among a subset of participants.

Attendees will leave with practical insights applicable to developmental evaluation, pilot program design, and the evaluation of complex social programs more broadly. The session will close with audience discussion that invites participants to reflect on how these findings apply to their own evaluation contexts.
