Background Recent investigations have demonstrated a significant prevalence of mental health disorders, including post-traumatic stress disorder (PTSD), and suicidal ideation, plans and attempts among Canadian public safety personnel, including police officers. What remains unknown is the relationship between mental disorders and suicide among sworn police officers, and the prevalence of both among civilian police workers. Aims To examine the relationship between suicidal ideation, plans and attempts and positive mental health screens for depression, anxiety, panic disorder, alcohol abuse and PTSD among Canadian sworn and civilian police employees. Methods Participants completed an online survey that included self-report screening tools for depression, anxiety, panic disorder, alcohol abuse and PTSD. Respondents were also asked if they ever contemplated, planned or attempted suicide. Between-group (Royal Canadian Mounted Police [RCMP], provincial/municipal police and civilians) differences on mental health screening tools were calculated using Kruskal–Wallis analyses. The relationship between mental disorders and suicidal ideation, plans and attempts was evaluated with a series of logistic regressions. Results There were 4236 civilian and sworn officer participants in the study. RCMP officers reported more suicidal ideation than other police and scored highest on measures of PTSD, depression, anxiety, stress and panic disorder, which were significantly associated with suicidal ideation and plans but not attempts. Relative to provincial and municipal police, civilians reported more suicide attempts and scored higher on measures of anxiety. Conclusions The results identify a strong relationship between mental health disorders and increased risk for suicidal ideation, plans and attempts among sworn and civilian Canadian police employees.

Suicide has long been considered as nearing ‘epidemic levels’ in law enforcement populations. Nevertheless, despite the argued scale of the problem, no review has yet systematically examined the evidence base to elucidate the risk factors or predictors implicated in the suicidal behaviours of police ofcers. The current review aims to do this, by considering a fnal sample of 20 papers that met inclusion criteria. Findings from this qualitative review revealed fve superordinate risk factors (i.e., problematic substance use close to, or at the time of death; presence of depression and previous suicide attempts; differences in trauma response; exposure to excessive and prolonged job-related stress, including dissatisfaction; absence of a stable intimate relationship), which when taken in isolation each incrementally contributed to suicide risk, but when found to be comorbid, appeared to markedly increase the likelihood of completed suicide. Implications for suicide prevention, policy design, and treatment formulation are discussed, along with limitations and directions for future research.
