An issue of major policy interest in the U.S. military has been interpersonal violence (IPV), especially relative to the frequent and lengthy deployments of U.S. service members to Iraq and Afghanistan. Lacking, however, are estimates of perpetrators of IPV, in particular, for reservists who have been 30% of the ground combat force. In the present study, Army National Guard soldiers (N = 4,567 in 50 company-sized units) responded to questions about deployment and combat, IPV, and suicidal behaviors. Over a tenth (12.2%) of the soldiers reported having done any aggressive behaviors toward significant others or children during postdeployment. More lengthy and repeated deployments were associated with perpetration of IPV. Having killed or wounded someone and having experienced some form of combat trauma were much more strongly associated with IPV perpetration. Suicidal behaviors were associated with having committed IPV, with the greatest risk associated with suicide attempts. Findings are discussed in terms of underlying mechanisms of both IPV perpetration and suicidal behaviors.

与国民警卫队士兵之间的人际暴力作案有关的部署经验和自杀行为。

与美军关系重大的政策问题是人际暴力（IPV），尤其是相对于美国服务人员频繁长期部署到伊拉克和阿富汗而言。但是，缺乏IPV犯罪者的估计，特别是对于占地面作战部队30％的预备役者而言。在本研究中，国民警卫队士兵（50个公司规模单位中的N = 4,567）回答了有关部署和战斗，IPV和自杀行为的问题。超过十分之一（12.2％）的士兵报告说，在部署后曾对重要的其他人或孩子采取过攻击性的行为。IPV的实施与冗长和重复的部署有关。杀害或伤害某人并遭受某种形式的战斗创伤与IPV犯罪密切相关。自杀行为与实施IPV有关，而自杀未遂的风险最大。根据IPV犯罪和自杀行为的潜在机制讨论了发现。
