Gender moderates the association of military sexual trauma and risk for psychological distress among VA-enrolled veterans.

Military sexual trauma (MST) is associated with increased risk for posttraumatic stress disorder (PTSD) and depression diagnoses, as well as suicidal ideation/behavior (SI/B). Little is known about the differential effect of gender on the association of MST and the aforementioned mental health outcomes. As females are the fastest growing subpopulation of the Veterans Health Administration (VHA), it is imperative to assess possible between-gender differences in the association of MST with PTSD, depression, and SI/B. Participants were 435,690 (n = 382,021, 87.7% men) 9/11 era veterans seen for care at the VHA between 2004 and 2014. Demographics, gender, PTSD and depression diagnoses, SI/B, and MST screen status were extracted from medical records. Adjusted logistic regression models assessed the moderating effect of gender on the association of MST with PTSD and depression diagnoses, as well as SI/B. Women with MST had a larger increased risk for a PTSD diagnosis (predicted probability =0.56, 95% confidence interval [CI] [0.56, 0.56]) and comparable risk for a depression diagnosis (predicted probability = 0.63, 95% CI [0.63, 0.64]) compared to men with MST. Men were more likely to have evidence of SI/B (predicted probability = 1.07, 95% CI [0.10, 0.11]) relative to women, but the interaction between gender and MST was nonsignificant. Data were limited to veterans seeking care through VHA and the MST screen did not account for MST severity. Non-VHA settings may consider screening for MST in both men and women, given that risk for PTSD and depression is heightened among female survivors of MST.

Comorbid PTSD and Depression Diagnoses Mediate the Association of Military Sexual Trauma and Suicide and Intentional Self-Inflicted Injury in VHA-Enrolled Iraq/Afghanistan Veterans, 2004-2014.

Exposure to military sexual trauma (MST) in veterans is associated with suicidal ideation. Previous research suggests there are mechanisms of this association, including posttraumatic stress disorder (PTSD) and depression. Research has yet to examine whether comorbid PTSD and depression mediate the association of MST and suicide and intentional self-inflicted injury, and whether this comorbidity confers a greater risk for suicide relative to PTSD-only and depression-only. The current study addressed this gap in our knowledge. Screening results identifying MST exposure, PTSD and depression diagnoses, suicide and intentional self-inflicted injury, and demographic covariates in 435,690 Iraq/Afghanistan veterans were extracted from Veterans Health Administration (VHA) medical records. Veterans were included if they attended VHA from 2004-2014. Mediation was tested with path analyses. Suicide and intentional self-inflicted injury was observed in 16,149 (3.71%) veterans. The indirect effect of suicide and intentional self-inflicted injury, given a positive screen for MST, was highest among veterans with comorbid PTSD and depression diagnoses (indirect effect=3.18%, 95% confidence interval [CI] [3.01%, 3.32%]), with smaller probabilities observed for both PTSD-only (indirect effect=-0.18%, 95% CI [-0.20%, -0.14%]) and depression-only (indirect effect=0.56%, 95% CI [0.51%, 0.62%]; ps<.05). Data were limited to VHA-enrolled Iraq/Afghanistan veterans. To reduce suicide risk among veterans with a history of MST, treatments may be most effective if they target comorbid PTSD and depression. Future research should examine the mechanisms through which comorbid PTSD and depression result in heightened risk for suicide and intentional self-inflicted injury.

Military sexual trauma and suicidal ideation in VHA-care-seeking OEF/OIF/OND veterans without mental health diagnosis or treatment.

Sexual trauma is a suicide risk factor. While military sexual trauma (MST) is frequently associated with suicidal ideation (SI) in women and men veterans who served in recent conflicts, less is known about MST's relationship to SI in veterans who have no documented mental health concerns. Of the 1.1 million post-9/11 veterans enrolled in the Veterans Healthcare Administration (VHA) we examined 41,658 (12.3% women, 87.7% men) without evidence of mental health diagnosis or treatment and who were screened for MST and SI using the standard VHA clinical reminders between 2008 and 2013. Relative risk estimates were generated using separate models for women and men. MST was reported by 27.9% of women and 2.9% of men; SI by 14.7% and 16.5%, respectively. The adjusted relative risk of MST on SI was 1.65 (95% CI 1.35, 2.00) in women, and 1.49 (95% CI 1.26, 1.75) in men. In this sample of veterans without evidence of mental health diagnosis or treatment, MST was associated with a high risk of SI in both genders. Positive MST screening should prompt SI screening and risk management if indicated, and further study of barriers to mental healthcare among MST survivors at risk for suicide is warranted.

Suicide Ideation in Female Survivors of Military Sexual Trauma: The Trauma Source Matters.

Female veterans who have experienced military sexual trauma (MST) are at elevated suicide risk, yet knowledge is limited regarding correlates of suicide ideation (SI) in this population. MST is associated with a higher risk of posttraumatic stress disorder (PTSD) relative to other trauma types; however, no studies have examined whether experiencing SI differs based on the source of PTSD symptoms (MST-related, non-MST-related). Female service members/veterans (SM/Vs; n = 311) who screened positive for MST and reported exposure to a Criterion A event completed an online survey assessing self-reported demographics, PTSD, depression, the source of their PTSD symptoms, and SI. Ninety-one (29.3%) reported experiencing current SI, and 223 (71.7%) identified MST as the source of their current PTSD symptoms. Participants who identified MST as the source of their PTSD symptoms were over two times more likely to report SI, compared to those who described non-MST-related events as the source of their PTSD symptoms. Compared to those who reported the source of their PTSD symptoms as combat-/deployment-related, those who identified MST as the source were at least three times as likely to report current SI. Results underscore the importance of efforts to address MST-related PTSD symptoms when working with female SM/Vs.
