OBJECTIVES: Examine the association between trauma and daily stressors, post-traumatic stress syndrome (PTSS), anxio-depressive disorders, and suicidal ideation in older adults.
DESIGN: A cross-sectional study.
SETTING AND PARTICIPANTS: This study included 1446 older adults recruited in primary care practices (2011-2013) and participating in Quebec's longitudinal study on health services in the elderly.
MEASUREMENTS: Lifetime trauma and PTSS was assessed using the validated PTSS scale for older adults based on scores from the Impact of Events Scale-Revised, number of lifetime traumatic events and interference with daily activities. The presence of an anxio-depressive disorder was based on physician diagnoses. Path analyses were conducted to determine the pathways between trauma, daily stressors, PTSS and anxio-depressive disorders and SI. Analyses were conducted on the overall sample and by sex.
RESULTS: Seven percent and 12% reported SI and PTSS. In males, traumas of sexual assault, violence/stalked, war/combat/imprisonment and daily hassles were directly associated with SI. In females, daily hassles were directly associated with SI. In males, a number of traumas were associated with SI through the mediating effect of PTSS and anxio-depressive disorders. In females, PTSS but not anxio-depressive disorders mediated the relationship between traumas and daily stressors, and suicidal ideation.
CONCLUSIONS: The effects of lifetime traumas persist well into older age. Traumas leading to SI differ between males and females as do the pathways and comorbidity with PTSS and anxio-depressive disorders. This highlights differences in etiologic patterns, which may be used in primary care practice to identify symptom profiles of older persons at risk of suicidal ideation.
