在一项对参与伊拉克部署的美国士兵的纵向研究中，我们考察了士气作为战斗暴露和创伤后应激障碍(PTSD)症状之间关系的调节因素。636名士兵在战斗部署后4个月(时间1)和10个月(时间2)完成评估。在时间1评估战斗暴露(广度和感受到的压力)、士气和创伤后应激障碍症状，在时间2再次评估创伤后应激障碍症状。多变量多元回归结果显示，时间1的士气与战斗暴露的广度和压力相互作用，在时间1和时间2预测创伤后应激障碍症状，即使在分割部队支持的影响的情况下也是如此。当报告的士气较高时，给定的战斗暴露与创伤后应激障碍症状之间的关系的斜率较弱(交互作用的影响大小在0.01到0.04之间)。结果表明，士气可能会缓冲士兵免受战斗压力的负面后果。
We examined morale as a moderator of the relationship between combat exposure and posttraumatic stress disorder (PTSD) symptoms in a longitudinal study of U. S. soldiers who had participated in a deployment to Iraq. Soldiers (N = 636) completed assessments at 4 (Time 1) and 10 (Time 2) months following their combat deployment. Combat exposure (both breadth and perceived stressfulness), morale, and PTSD symptoms were assessed at Time 1, and PTSD symptoms were assessed again at Time 2. Results of multivariate multiple regressions revealed that morale at Time 1 interacted with both the breadth and stressfulness of combat exposure to predict PTSD symptoms at both Time 1 and Time 2, even when partialling out the effect of unit support. The slope of the given combat exposure and PTSD symptoms relationship was weaker when reports of morale were higher (with the effect size of the interaction ranging from .01 to .04). The results suggest that morale may buffer soldiers from the negative consequences of combat stressors.
