Abstract:
We know little about potentially psychologically traumatic events (PPTE) exposures among provincial correctional workers in diverse occupational positions and even less regarding how exposure to events are associated with mental health disorders. We designed the current study to unpack and quantify estimates of the frequencies that correctional workers, across occupational roles, experience exposure to diverse incidents. We categorized 1,338 of our 1,487 participants into six occupational categories and our measures included established self-report items measuring PPTE exposure and mental disorder symptoms. Almost all correctional workers reported exposures to most PPTE types. Correctional workers collectively report exposures to physical assault (90.2%) and sudden violent death (81.8%), with many (3.1%-46%) reporting 11+ exposures (M = 10.01, SD = 4.29). We found significant differences in exposure patterns across correctional worker categories; specifically, we found a higher prevalence of exposure to toxic substances, physical assault, assault with a weapon, severe human suffering, sudden accidental or sudden violent death, among those working in institutional correctional services (e.g., governance, correctional officers). PPTE exposure and all assessed mental health disorder symptom profiles were closely related, as correctional workers report high exposure to PPTE. Population attributable fractions indicated that the burden of mental disorders among provincial correction workers might be reduced by between 38%-70% if PPTE exposures were eliminated from the population. We conclude with recommendations for mental health related policies, such as investing in peer and psychologically support, as well as interventions for exposure to PPTE and readiness to inform strategies for employee mental health and well-being.
