Psychological and Physical Health Effects of Sexual Assaults and Nonsexual Traumas Among Male and Female United States Army Soldiers

Abstract Lifetime trauma history was assessed in a health study of active duty United States Army soldiers. Five hundred fifty-five male and 573 female soldiers in the sample were asked whether they had ever experienced 14 different potentially traumatic experiences, including sexual assaults, violent stressors to self, and terrifying events that occurred to others and were secondarily traumatic through exposure by gaining information or as a witness to the event. Most soldiers had experienced multiple traumas, and premilitary exposure to events was much more common than exposure to events after entering the military. Global measures of current psychological distress and physical health symptoms were predicted by the lifetime number of sexual assaults and traumas to self. Social support from military unit leaders moderated the relationship between accumulated exposure to traumas and both health measures, whereas unit cohesion was directly associated with fewer mental health problems.

The Effects of Peer Group Climate on Intimate Partner Violence among Married Male U.S. Army Soldiers

This study examined the combined impact of individual-level and group-level variables on self-reported intimate partner violence, operationally defined as mild to severe physical aggression on the Modified Conflict Tactics Scale, among married male U.S. Army soldiers. The sample comprised 713 servicemen from 27 companies stationed at an Army post in the Alaskan interior. Group-level variables were based on individual reports on various dimensions of group climate aggregated at the company level. Contextual analyses were conducted using a variety of regression approaches. Individual-level predictor variables significantly associated with intimate partner violence included race, symptoms of depression, poor marital adjustment, alcohol problems, and a history of childhood abuse. Group-level predictor variables significantly associated with intimate partner violence included lower leadership support (vertical cohesion), a culture of hyper-masculinity (operationally defined as increased group disrespect), and lower support for spouses.

Intimate partner violence among married male U.S. Army soldiers: ethnicity as a factor in self-reported perpetration and victimization.

Correlates of self-reported intimate partner violence (IPV) were examined among 488 married male U.S. Army soldiers. Study results were examined within the framework of Johnson’s (1995) typology, which proposes that there are two main types of IPV, common couple violence and intimate terrorism. We predicted that poor marital adjustment would be associated with minor violence, hypothesized to be indicative of common couple violence. We also predicted that psychological and behavioral characteristics associated with perpetrators of IPV would be more strongly correlated with severe inflicted aggression—a pattern hypothesized to be indicative of intimate terrorism. The results, based on a multivariate analysis of covariance, generally supported our hypotheses. Furthermore, the higher levels of IPV reported by Black respondents in this study were associated with the pattern hypothesized to be characteristic of common couple violence.
