Increasing attention has been focused on suicidal behavior among military personnel. Exposure to deployment-related traumatic events (DRTEs) and child abuse (CA) both have been associated with mental disorders and suicidal behaviors among military personnel. Thus, the primary objectives of this study were to examine (a) sex differences in CA history and DRTEs, past-year mental disorders, and past-year suicide-related outcomes and (b) independent, cumulative, and interactive effects of CA history and DRTEs on past-year mental disorders and suicide outcomes among Canadian military personnel. Data were from the representative Canadian Forces Mental Health Survey collected in 2013 (N = 8,161; response rate = 79.8%). The results indicated a high prevalence of trauma exposure, with sex differences noted for specific trauma types. Both CA history and DRTEs were strongly associated with mental disorders, CA history: aORs = 1.60–2.44; DRTEs; aORs = 1.67–3.88. Cumulative, but not interactive, effects were noted for the effects of CA history and DRTEs on most mental disorders. Associations between CA history and DRTEs on suicide outcomes were largely indirect via their impact on mental disorders. Information regarding the role of specific types of predeployment trauma on mental disorders and suicidal behavior can be used to develop more targeted prevention and intervention strategies aimed at improving the mental health of military personnel.

加拿大正规部队人员虐待儿童史、部署相关创伤事件、精神障碍和自杀行为之间的关联

越来越多的注意力集中在军人的自杀行为上。暴露于部署相关的创伤事件 (DRTE) 和虐待儿童 (CA) 都与军事人员的精神障碍和自杀行为有关。因此，本研究的主要目的是检查 (a) CA 病史和 DRTE、过去一年的精神障碍和过去一年的自杀相关结果的性别差异，以及 (b) CA 病史的独立、累积和交互影响和 DRTEs 关于加拿大军事人员过去一年的精神障碍和自杀结果。数据来自 2013 年收集的具有代表性的加拿大军队心理健康调查（N= 8,161；响应率 = 79.8%）。结果表明，创伤暴露的发生率很高，特定创伤类型存在性别差异。CA 病史和 DRTE 均与精神障碍密切相关，CA 病史：a OR s = 1.60-2.44；DRTE；a OR s = 1.67–3.88。CA 病史和 DRTE 对大多数精神障碍的影响是累积的，但不是交互的。CA 病史和 DRTE 对自杀结果之间的关联在很大程度上是间接的，因为它们对精神障碍的影响。有关特定类型的部署前创伤对精神障碍和自杀行为的作用的信息可用于制定更有针对性的预防和干预策略，以改善军人的心理健康。
