Work‐related suicide: Evolving understandings of etiology & intervention

Abstract

AbstractPreviously published analyses of suicide case investigations suggest that work or working conditions contribute to 10%–13% of suicide deaths. Yet, the way in which work may increase suicide risk is an underdeveloped area of epidemiologic research. In this Commentary, we propose a definition of work‐related suicide from an occupational health and safety perspective, and review the case investigation‐based and epidemiologic evidence on work‐related causes of suicide. We identified six broad categories of potential work‐related causes of suicide, which are: (1) workplace chemical, physical, and psychosocial exposures; (2) exposure to trauma on the job; (3) access to means of suicide through work; (4) exposure to high‐stigma work environments; (5) exposure to normative environments promoting extreme orientation to work; and (6) adverse experiences arising from work‐related injury or illness. We summarise current evidence in a schema of potential work‐related causes that can also be applied in workplace risk assessment and suicide case investigations. There are numerous implications of these findings for policy and practice. Various principle‐ and evidence‐based workplace intervention strategies for suicide prevention exist, some of which have been shown to improve suicide‐prevention literacy, reduce stigma, enhance helping behaviours, and in some instances maybe even reduce suicide rates. Prevailing practice in workplace suicide prevention, however, overly emphasises individual‐ and illness‐directed interventions, with little attention directed to addressing the working conditions that may increase suicide risk. We conclude that a stronger emphasis on improving working conditions will be required for workplace suicide prevention to reach its full preventive potential.
