Male sex and hazardous alcohol use following military sexual assault increase suicide risk among US service members and veterans

Background: Higher alcohol use and military sexual assault (MSA) are associated with increased risk of death by suicide. Risk for death by suicide is rapidly increasing among females, who report higher rates of MSA, yet actual death by suicide and alcohol use are higher among males. It is not well understood whether higher alcohol use confers greater suicide risk in male or female service members and veterans who have experienced MSA.Objective: To determine whether the association between alcohol misuse and suicide risk was moderated by biological sex in a sample of male and female service members (N = 400, 50% female) who reported MSA.Method: Participants completed surveys of alcohol use and suicide risk as well as a demographic inventory. Linear regression with an interaction term was used to determine if suicide risk differed by sex and alcohol use severity after accounting for discharge status, sexual orientation, and age.Results: Average scores on the suicide risk measure were consistent with an inpatient psychiatric sample and scores on the AUDIT-C were indicative of a probable positive screen for alcohol misuse. Suicide risk was most pronounced among males who reported higher levels of hazardous alcohol use. A sensitivity analysis examining suicide risk by sex and screening results for alcohol misuse (positive/negative) showed that men with a probable positive screen had higher suicide risk.Discussion: The current study provides novel findings on suicide risk among survivors of military sexual violence by including both male and female survivors. Interventions to decrease suicide risk following MSA may consider alcohol reduction strategies, and optimizing these interventions in males. Engaging military culture at both the US Departments of Defense and Veterans Affairs to encourage more healthy alcohol consumption may mitigate this public health concern. Future research may consider how country of origin relates to these associations.

Negative posttraumatic cognitions about self potentially mediate the relation between sexual revictimization and suicide risk in a sample of military sexual assault survivors

OBJECTIVE

Military sexual trauma (MST) is a risk factor for suicide among service members/veterans. Research reported that around half of MST survivors were exposed to pre-MST, making MST a revictimization experience. Unfortunately, little is known about mechanisms of the association between revictimization and suicide risk among MST survivors. One possible mechanism is posttraumatic cognitions (PTCs), which include the survivor's (a) negative cognitions about themselves, (b) negative cognitions about the world, and (c) self-blame. The current study examined each of the PTC subscales as potential mediators of the association between sexual revictimization and suicide risk.

METHOD

Participants were 383 service members/veterans reporting a history of MST that involved assault (50.65% female). Participants completed self-report questionnaires assessing demographics, suicide risk, history of sexual victimization (MST and premilitary sexual victimization), and PTCs. Of these, 340 (88.8%) reported a history of MST and premilitary victimization and comprised the revictimization group.

RESULTS

Parallel mediation analysis with suicide risk regressed on each of the PTCs subscales and covariates revealed that negative cognitions about self had a significant indirect effect on the association between revictimization and higher suicide risk, above and beyond negative cognitions about the world and self-blame.

CONCLUSIONS

Targeting negative cognitions about self among sexual revictimization survivors may be a therapeutic strategy to reduce suicide risk most effectively. Cognitive processing therapy may be particularly useful given the focus on altering PTCs. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
