Posttraumatic stress disorder (PTSD) can occur subsequent to war stress, but not all troops are negatively affected. A discriminant function model was used to study associations between personal and environmental resources and psychological outcomes subsequent to war zone stress. Among 775 Persian Gulf War exposed troops, 2 subsets were identified: 97 with PTSD diagnoses and 484 who had no psychological distress. A discriminant function, double cross-validated in random subsamples, classified 87% of troops, and demographic and stress severity variables did not alter results significantly. Personality hardiness commitment, avoidance coping, and perceived family cohesion emerged as consistent predictors of PTSD diagnosis. Findings suggest personal characteristics and environmental factors may alter vulnerability to negative war stress outcomes. Work is needed to identify mechanisms and causal pathways by which resource factors enhance or lower stress resistance.
创伤后应激障碍（PTSD）可能在战争压力之后出现，但并非所有部队都会受到负面影响。使用判别函数模型来研究个人和环境资源与战区压力后心理结果之间的关联。在775名曾经历海湾战争的部队人员中，识别出了两个亚组：97名被诊断患有创伤后应激障碍的人员和484名没有心理困扰的人员。在随机子样本中进行双重交叉验证的判别函数对87%的部队人员进行了分类，人口统计学和压力严重程度变量并未显著改变结果。性格坚韧、回避应对和感知到的家庭凝聚力成为创伤后应激障碍诊断的一致预测因素。研究结果表明，个人特征和环境因素可能会改变对负面战争压力结果的易感性。需要开展工作来确定资源因素增强或降低压力抵抗力的机制和因果途径。
