PURPOSE: The aim of this study was to describe the knowledge to action and knowledge transfer approaches used in an international mental health research funding program and its outcomes. A key goal of the evaluation was to maximise organisational learning and knowledge sharing to inform future implementation projects. METHODS: A series of interactive knowledge sharing workshops focused on five key themes: peer support
psychoeducation
the involvement of family, friends, and significant others
retreat, residential, or group-based programs
and organisational change. Qualitative descriptive analysis was used to code, summarise and describe themes. FINDINGS: Key learnings that influenced the success of mental health initiatives include building relationships across all organisational levels, involving Veterans and First Responders with lived experience in the design and implementation process, and understanding the unique workplace culture and operations. CONCLUSION: Our findings highlight the need for collaborative, informed approaches tailored to the culture, organisation and mental health support needs of Veteran and First Responder. These insights enhance understanding of the factors that impact the successful implementation of mental health prevention and support programs for those exposed to work-related trauma.
