失眠是军事部署的一种常见和有害的后果，但对部署前导致部署后失眠的风险因素知之甚少。威胁学习倾向异常在失眠症患者中很常见，对压力的不适应反应与失眠的发生有关，这表明威胁学习可能是部署后失眠的一个重要危险因素。在这里，我们研究了部署前威胁学习作为部署后失眠的预测因子，以及这种影响的潜在机制。814名男性军人在军事部署前后完成了失眠、精神症状和威胁学习任务的测量。威胁学习指数区分部署后有无失眠的参与者被测试为部署前部署后失眠的预测因子。部署后失眠与部署后几个威胁学习指数的上升有关，但只有较高的威胁条件作用，如对危险线索的较高威胁预期评级，才会成为部署前部署后失眠的预测指标。这种影响与战斗暴露水平无关，并部分受到部署后更大的噩梦的影响。在遇到危险线索后，人们倾向于对厌恶事件产生更强烈的预期，这可能会增加部署后失眠的风险，部分原因是出现更严重的噩梦。
Insomnia is a common and impairing consequence of military deployment, but little is known about pre-deployment risk factors for post-deployment insomnia. Abnormal threat learning tendencies are commonly observed in individuals with insomnia and maladaptive responses to stress have been implicated in the development of insomnia, suggesting that threat learning could be an important risk factor for post-deployment insomnia. Here, we examined pre-deployment threat learning as a predictor of post-deployment insomnia and the potential mechanisms underlying this effect. Male servicemembers (N = 814) completed measures of insomnia, psychiatric symptoms, and a threat learning task before and after military deployment. Threat learning indices that differentiated participants with versus withoutinsomnia at post-deployment were tested as pre-deployment predictors of post-deployment insomnia. Post-deployment insomnia was linked to elevations on several threat learning indices at post-deployment, but only higher threat conditioning, as indexed by higher threat expectancy ratings to the danger cue, emerged as a pre-deployment predictor of post-deployment insomnia. This effect was independent of combat exposure levels and partially mediated by greater post-deployment nightmares. The tendency to acquire stronger expectations of aversive events following encounters with danger cues may increase risk for post-deployment insomnia, in part due to the development of more severe nightmares.
