IntroductionPrevious research has demonstrated an association between military sexual trauma and risk for suicide; however, risk for self-directed violence such as suicide attempt or nonsuicidal self-injury following military sexual trauma is understudied. This study examines the relationship between military sexual trauma and serious self-directed violence resulting in hospitalization, as well as whether this relationship differs by sex.MethodsParticipants were 750,176 Operations Enduring Freedom/Iraqi Freedom/New Dawn veterans who were enrolled in Veterans Health Administration care during the period of October 1, 2001-September 30, 2014 and who were screened for military sexual trauma. Data were analyzed in 2019. Bivariate analyses and Cox proportional hazards regression models were employed.ResultsWomen veterans were more likely to screen positive for military sexual trauma (21.33% vs 1.63%), and women and men were equally likely to experience serious self-directed violence (1.19% women vs 1.18% men). Controlling for demographic variables and psychiatric morbidity, military sexual trauma predicted serious self-directed violence for both men and women. Further, men with military sexual trauma were 15% less likely to experience self-directed violence compared with women with military sexual trauma (hazard ratio=0.85, 95% CI=0.74, 0.98).ConclusionsMilitary sexual trauma is associated with risk for serious self-directed violence for both men and women veterans, and the relationship may be pronounced among women. Results underscore the importance of incorporating military sexual trauma into treatment and preventative efforts for self-directed violence.Copyright © 2020 American Journal of Preventive Medicine.
