Investigating the effects of suicide exposure among a clinical sample of active duty service members

Abstract

Suicide exposure warrants further investigation as a risk factor for suicide among military service members. This study aimed to examine associations among suicide exposure, suicidal ideation (SI), and psychological symptoms in a clinical sample of service members (N = 1,565, 64.4% suicide-exposed) and identify how one's relationship with the deceased impacts suicidality and psychological health in exposed individuals. A secondary analysis of cross-sectional survey data was conducted. Generalized linear regression analyses were used to identify associations between suicide exposure and both current SI and psychological symptoms among all participants; the associations between suicide exposure characteristics and psychological symptoms were only examined among exposed individuals.Exposure was not significantly associated with higher SI, β = .007, SE = .16, p = .965, but was associated with PTSD, β = 1.60, SE = 0.49, p = .001; anxiety, β = .68, SE = .31, p = .031; and insomnia symptoms, β = .98, SE = .25, p < .001. Among participants who had been exposed, high/long impact of exposure was positively associated with SI, β = 0.94, SE = .26, p < .001, and psychological symptoms, PTSD: β = 2.32, SE = .77, p = .002; anxiety: β = 1.39, SE = .50, p = .005; insomnia: β = .96, SE = .39, p = .015. Results illustrate the significant issue of suicide exposure within the military and show consideration of suicide exposure as a potential risk factor for adverse psychological outcomes is warranted.Despite concerted prevention efforts, military suicide rates have risen for more than a decade (Armed Forces Health Surveillance Center [AFHSC], 2014; Psychological Health Center of Excellence [PHCoE], 2020). Suicide is currently the second leading cause of death within the military, with approximately 500 U.S. active duty service members and Reserve and National Guard personnel dying by suicide each year and thousands more attempting to end their lives (PHCoE, 2020).
