This study assessed the contribution of baseline psychological symptoms, combat exposure, and unit support in the etiology of posttraumatic stress disorder (PTSD), and psychological distress. From 2004-2006, 67% of a random sample of 2,820 participants who had been assessed for psychological symptoms in 2002 were reassessed. Baseline psychological symptoms, combat exposure, and unit support factors were associated with the outcomes and the effect sizes for combat exposure were marked for PTSD symptoms. Adjustment for baseline psychological symptoms did not modify the pattern of association of group cohesion and combat exposures. The authors concluded that combat exposure and group cohesion have an effect on mental health outcomes independent of previous mental health status, which explains why screening prior to deployment is ineffective.
本研究评估了基线心理症状、战斗暴露及单位支持在创伤后应激障碍（PTSD）病因及心理困扰方面的作用。2004年至2006年，对2002年接受过心理症状评估的2820名参与者的随机样本中的67%进行了重新评估。基线心理症状、战斗暴露及单位支持因素与结果相关，战斗暴露对PTSD症状的效应量显著。对基线心理症状进行调整并未改变群体凝聚力与战斗暴露之间的关联模式。作者得出结论，战斗暴露和群体凝聚力对心理健康结果的影响独立于先前的心理健康状况，这解释了部署前筛查为何无效。
