The Effects of Adverse Childhood Experiences and Warfare Exposure on Military Sexual Trauma Among Veterans.

Military sexual trauma (MST) is a pervasive problem; this study examined the relationship of the precursory traumas of adverse childhood experiences (ACEs) and warfare exposure with MST. Post-9/11 veterans were surveyed at 3 months and at 24 to 30 months post-military separation. Female veterans who experienced at least 1 ACE but no warfare exposure were significantly more likely to receive unwanted sexual attention. Veterans (males and females) experiencing three or more ACEs but no warfare exposure were significantly more likely to receive unwanted sexual attention and contact. Experiencing only warfare exposure was not related to unwanted sexual attention or contact for females; however, a significant interaction was found between combined warfare exposure, ACEs, and MST for males and females. Veterans who reported warfare exposure and one to two or three or more ACEs were more likely to report unwanted sexual attention and/or contact. Exploration of individual ACEs revealed a significant relationship between childhood sexual abuse and unwanted sexual contact. For females, witnessing domestic violence predicted unwanted sexual contact. There was also a significant interaction between childhood sexual abuse and warfare exposure. Females who experienced both childhood sexual abuse and warfare exposure were significantly more likely to receive unwanted sexual attention and unwanted sexual contact. Albeit a small sample, males who experienced both were also significantly more likely to receive unwanted sexual attention. The findings reveal that precursory traumatic experiences in childhood and the interaction of ACEs and warfare exposure during military service can increase the likelihood of unwanted sexual attention and contact. This research further substantiates the need for screening efforts. It also demonstrates the importance of practitioners engaging in trauma-informed care principles and practices to address the residual effects of previous experiences during sexual trauma or mental health treatment efforts.

The interaction of exposure to adverse childhood and combat experiences on the current mental health of new post-9/11 veterans.

Military veterans have greater exposure to adverse childhood experiences (ACEs) than civilians and many also encounter warfare exposures, which can increase the likelihood of mental health problems. The purpose of this study was to test an interaction between childhood traumas and warfare exposures on the mental health of a sample of nearly 10,000 new post-9/11 veterans. Results revealed that male veterans exposed to one or two ACEs, but no warfare, were more likely to experience anxiety, depression, suicidal thinking, and angry outbursts than the reference group (i.e., no ACEs and no warfare exposure). Female veterans exposed to one or two ACEs, but no warfare, were only more likely to experience suicidal thinking. Male and female veterans exposed to three or more ACEs and no warfare were more likely to experience probable posttraumatic stress disorder (PTSD), anxiety, depression, suicidality, and angry outbursts. Among those veterans who experienced corollaries of combat only (e.g., seeing someone killed or seriously wounded), male, but not female veterans were more likely to have probable PTSD, anxiety, and depression. Veterans exposed to warfare (i.e., combat and the corollaries of combat), irrespective of ACEs exposure, were the most likely to report mental health symptoms. Implications for community-based mental health services are discussed.
