<p>Military service involves a number of demands and potential exposures to traumatic events during deployment, which can increase members’ risk of developing mental health issues. Research has examined how to mitigate these risks and build resilience among military members. One concept that has shown promise in this regard based on studies of military personnel deployed on operations is that of mental health-specific leadership (e.g., encouraging care-seeking, showing concern for how families deal with stress). However, limited research to date has examined mental health-specific leadership in the Canadian military context, particularly during a worldwide crisis. To address this gap, the current study examined how often mental health-specific leadership behaviours were reported within the Canadian Armed Forces (CAF) during the COVID-19 pandemic and examined associations between these leadership behaviours and CAF members’ mental health. A cross-sectional electronic survey was administered to a stratified random sample of 2,747 CAF members in 2021. Most members reported observing leaders engaging in these behaviours, and a series of linear regressions identified significant associations between an overall measure of mental health-specific leadership and members’ positive self-rated mental health and well-being. These findings can support efforts to promote positive health behaviours and care-seeking to build resilience among military members.</p>
