The study examined dispositional optimism s role in buffering the effect of warzone stress on mental health symptoms and mental health symptoms on work impairment. A total of 2,439 soldiers from an active-duty brigade combat team were surveyed following a 12-month deployment to Iraq. Posttraumatic stress disorder (PTSD) symptoms, depression symptoms, combat exposure, deployment demands, and work impairment were measured. Soldiers higher in dispositional optimism showed weaker relationships between combat exposure and PTSD symptoms, and between deployment demands and PTSD and depression symptoms. Dispositional optimism also buffered mental health symptom effects on work impairment. Dispositional optimism may protect soldiers from warzone stress and mental health symptoms. Potential mechanisms explaining how dispositional optimism may serve as a protective factor are discussed.
本研究考察了性格乐观主义在缓冲战区压力对心理健康症状的影响，以及心理健康症状对工作障碍的影响中的作用。共有 2439 名来自现役旅战斗队的士兵在部署到伊拉克 12 个月后接受了调查。评估了创伤后应激障碍（PTSD）症状、抑郁症状、战斗暴露、部署需求和工作障碍。性格乐观程度较高的士兵在战斗暴露与 PTSD 症状之间，以及在部署需求与 PTSD 和抑郁症状之间的关系较弱。性格乐观主义也缓冲了心理健康症状对工作障碍的影响。性格乐观主义可能会保护士兵免受战区压力和心理健康症状的影响。讨论了性格乐观主义如何作为保护因素的潜在机制。
