Public safety personnel (PSP) and their families are significantly affected by occupational stressors, including exposure to potentially psychologically traumatic events, physical risks, and operational demands that disrupt family dynamics. While PSP frequently rely on family support, these families often lack formal resources, contributing to work-family conflict and diminished well-being. This study employed a co-design methodology to develop a family-forward toolkit for Canadian public safety organisations, aiming to support the development and implementation of family-forward initiatives. Drawing on previous findings from a qualitative systematic review, environmental scan, and interviews, the toolkit was collaboratively co-designed through iterative focus groups, interviews, and a final survey. PSP participants validated the toolkit’s relevance and usability, highlighting its applicability across organisational roles and family readiness levels. The toolkit provides tailored initiative recommendations, planning worksheets, and strategic prompts aligned with organisational context and readiness. Feedback emphasised its practicality, with areas for refinement including user interface design, clarity of terminology, and inclusion of implementation supports. This study demonstrates the value of participatory design in developing evidence-informed, context-sensitive resources for high-risk occupational groups. Future research should include PSP family members in toolkit refinement and assess real-world implementation outcomes.
