There is growing evidence that disturbed sleep is a risk factor for the development of a number of psychiatric diagnoses including depression, PTSD and substance use. The goal of this study was to use a subset of participants from a larger prospective longitudinal study to examine whether preexisting daytime and nighttime sleep disturbances predict depression, PTSD and substance use in US National Guard Soldiers deployed to Iraq. Data on daytime and nighttime sleep complaints, baseline symptoms and personality variables were gathered prior to deployment to Iraq. Measures of psychopathology were collected at three time points post-deployment over the course of two years using both questionnaires and interviews. Multiple regressions were used to predict diagnoses and symptoms of depression, PTSD and substance use. Pre-deployment daytime and nighttime sleep complaints contributed significantly to the prediction of PTSD and depression up to two years after deployment, but not substance use. This study suggests that daytime and nighttime sleep complaints are a risk factor for internalizing disorders including PTSD and depression.
越来越多的证据表明，睡眠紊乱是许多精神疾病诊断的风险因素，包括抑郁症、创伤后应激障碍和物质使用障碍。本研究的目的是使用一个更大的前瞻性纵向研究的参与者子集，来检验美国国民警卫队士兵在部署到伊拉克之前的日间和夜间睡眠障碍是否会预测抑郁、创伤后应激障碍和物质使用。在部署到伊拉克之前，收集了日间和夜间睡眠投诉、基线症状和人格变量的数据。在两年的时间里，通过问卷调查和访谈，在部署后的三个时间点收集了精神病理学的测量结果。多元回归用于预测诊断和抑郁、创伤后应激障碍和物质使用障碍的症状。在部署后的两年内，与物质使用障碍相比，部署前的日间和夜间睡眠问题显著预测了创伤后应激障碍和抑郁。本研究表明，日间和夜间睡眠问题是包括创伤后应激障碍和抑郁在内的内化障碍的风险因素。
