Sleep disturbance may be the most often endorsed symptom of posttraumatic stress disorder (PTSD). Much of this research is based on subjective reports from trauma survivors; however, objective measures of sleep-related impairment have yielded findings inconsistent with self-report data. More studies investigating subjective and objective assessments concordantly are needed to understand sleep impairment in PTSD. The current study examined PTSD-related sleep disturbance in a female interpersonal violence cohort with full PTSD diagnoses (N=51) assessing subjective (global and daily diary measures) and objective (actigraphy) sleep measures concurrently. PTSD severity was positively associated with global, subjective reports of sleep impairment and insomnia. Subjective measures of sleep (including global sleep impairment, insomnia, and daily sleep diary reports of total sleep time, sleep efficiency, and sleep onset latency) were moderately to strongly correlated. However, no significant correlations between subjective and objective reports of sleep impairment were found in this cohort. Analyses demonstrated an overall elevation in subjectively reported sleep impairment when compared to objective measurement assessed concurrently. Findings demonstrate a lack of agreement between subjective and objective measurements of sleep in a PTSD-positive female cohort, suggesting objective and subjective sleep impairments are distinct sleep parameters that do not necessarily directly co-vary.
睡眠障碍可能是创伤后应激障碍（PTSD）中最常被认可的症状。这项研究大多基于创伤幸存者的主观报告；然而，与睡眠相关的损害的客观测量结果与自我报告数据并不一致。需要更多同时调查主观和客观评估的研究来了解PTSD中的睡眠损害情况。本研究在一个患有完全PTSD诊断的女性人际暴力队列（N = 51）中，同时评估主观（整体和每日日记测量）和客观（活动记录仪）睡眠测量，研究与PTSD相关的睡眠障碍。PTSD严重程度与整体睡眠损害和失眠的主观报告呈正相关。睡眠的主观测量（包括整体睡眠损害、失眠以及每日睡眠日记中总睡眠时间、睡眠效率和入睡潜伏期的报告）之间存在中度到高度的相关性。然而，在这个队列中，睡眠损害的主观和客观报告之间未发现显著相关性。分析表明，与同时进行的客观测量相比，主观报告的睡眠损害总体上有所升高。研究结果表明，在PTSD阳性女性队列中，睡眠的主观和客观测量之间缺乏一致性，这表明客观和主观睡眠损害是不同的睡眠参数，不一定直接共同变化。
