Firefighters represent a group at elevated suicide risk. Identifying segments of the fire service at increased risk may facilitate the targeted provision of suicide prevention initiatives. Among the general population, American Indian/Alaska Native (AI/AN) individuals report higher rates of suicide attempts. This study sought to examine suicide attempt rates among AI/AN firefighters and to determine if greater exposure to painful and provocative events and/or fearlessness about death explains the relationship between AI/AN identity and suicidal behaviors. A total of 917 US firefighters completed a web-based mental health survey (6.2% AI/AN). Participants completed a modified version of the Self-Injurious Thoughts and Behaviors Interview-Short Form, the Painful and Provocative Events Scale, and the Acquired Capability for Suicide Scale-Fearlessness About Death scale. Bootstrap mediation analyses were conducted, controlling for years of service as a firefighter. Although AI/AN firefighters accounted for only 6.2% of the sample, they accounted for 34.4% of the career suicide attempts. AI/AN firefighters were 16.31 (95% CI?=?7.96, 33.42) times more likely to report a career suicide attempt history than non-AI/AN firefighters, adjusting for years of service as a firefighter. Painful and provocative events, but not fearlessness about death, was a statistically significant mediator of the relationship between AI/AN identity and suicide attempts. Firefighters identifying as AI/AN represent a subgroup within the fire service at increased risk for suicide. Findings suggest that greater exposure to painful and provocative events among AI/AN firefighters may explain the elevated suicide risk among this population.
