Studies have found a stronger association between anger and posttraumatic stress disorder (PTSD) severity in military populations than in nonmilitary populations. Two hypotheses have been proposed to explain this difference: Military populations are more prone to anger than nonmilitary populations, and traumas experienced on deployment create more anger than nondeployment traumas. To examine these hypotheses, we evaluated the association between anger and PTSD severity among never-deployed military service members with nondeployment traumas (n = 226) and deployed service members with deployment traumas (n = 594) using linear regression. We further examined these associations stratified by gender. Bivariate associations between anger and PTSD severity were similar for nondeployment and deployment events; however, gender modified this association. For men, the association for deployment events was stronger than for nondeployment events (β = .18, r = .53 vs. β = .16, r = .37, respectively), whereas the reverse was true for women (deployment: β = .20, r = .42 vs. nondeployment: β = .25, r = .65). Among men, findings supported the hypothesis that deployment traumas produce stronger associations between PTSD and anger and are inconsistent with hypothesized population differences. In women, however, there was not a clear fit with either hypothesis.
研究发现，与非军事人群相比，军事人群中愤怒与创伤后应激障碍（PTSD）严重程度之间的关联更强。针对这种差异，人们提出了两种假设：军事人群比非军事人群更容易愤怒，以及部署期间经历的创伤比非部署创伤引发更多愤怒。为了检验这些假设，我们使用线性回归评估了有非部署创伤的从未部署过的军人（n = 226）和有部署创伤的已部署军人（n = 594）中愤怒与PTSD严重程度之间的关联。我们还按性别对这些关联进行了分层分析。非部署事件和部署事件中，愤怒与PTSD严重程度之间的双变量关联相似；然而，性别改变了这种关联。对于男性，部署事件的关联比非部署事件更强（β = 0.18，r = 0.53，而非部署事件β = 0.16，r = 0.37），而女性则相反（部署：β = 0.20，r = 0.42，非部署：β = 0.25，r = 0.65）。在男性中，研究结果支持了这样的假设，即部署创伤在PTSD与愤怒之间产生更强的关联，且与假设的人群差异不一致。然而，在女性中，两种假设都不太契合。
