睡眠障碍和人际关系问题在患有创伤后应激障碍（PTSD）的退伍军人中非常普遍，并且与大量的合并症和增加的医疗费用有关。本研究探讨了人际依恋风格和睡眠在一个高风险队列的退伍军人PTSDsymptoms.METHODSParticipants之间的关联49名退伍军人（85%男性）参加了治疗研究的战斗相关的睡眠障碍。在治疗前基线时收集数据。依恋焦虑和回避，临床特征和主观睡眠质量的特点，通过自我报告。多导睡眠图睡眠测量是从两个晚上的实验室睡眠研究中取平均值，包括：视觉评分的持续时间和连续性，3+4阶段睡眠和快速眼动（REM）睡眠的百分比，以及NREM和REM睡眠期间δ和β功率的定量脑电图（QEEG）测量。线性回归评估了依恋类型与睡眠之间的关系，并调整了人口统计学、创伤后应激障碍和抑郁症状。结论：依恋焦虑程度越高，3+4期睡眠的百分比越低（β=-0.36，p<0.05），非快速眼动睡眠期间的相对β功率越高（β=0.40，p<0.05）。相比之下，在NREM和REM睡眠期间，更大的依恋回避与δ功率呈正相关（β分别为0.35和0.38，p<0.05）。阐明PTSD相关睡眠障碍的神经生物学和心理学相关性对于制定未来旨在减轻PTSD负担的有针对性的干预措施至关重要。
BACKGROUNDSleep disturbances and interpersonal problems are highly prevalent in military veterans with post-traumatic stress disorder (PTSD) and are associated with substantial comorbidities and increased healthcare costs. This study examines the association between interpersonal attachment styles and sleep in a high-risk cohort of military veterans with PTSD symptoms.METHODSParticipants were 49 military veterans (85% male) enrolled in a treatment study of combat-related sleep disturbances. Data were collected at pre-treatment baseline. Attachment anxiety and avoidance, clinical characteristics, and subjective sleep quality were characterised via self-report. Polysomnographic sleep measures were averaged from two nights of in-laboratory sleep studies and included: visually scored duration and continuity, the percentage of stage 3+4 sleep and rapid eye movement (REM) sleep, and quantitative electroencephalographic (QEEG) measures of delta and beta power during NREM and REM sleep. Linear regressions evaluated the relationship between attachment styles and sleep with adjustment for demographics, and PTSD and depressive symptoms.RESULTSGreater attachment anxiety was associated with reduced percentage of stage 3+4 sleep, (β=−0.36, p<0.05) and increased relative beta power during NREM sleep (β=0.40, p<0.05). By contrast, greater attachment avoidance was positively associated with delta power during NREM and REM sleep (β=0.35 and 0.38, respectively, p<0.05).CONCLUSIONSThese findings suggest specific effects of interpersonal styles on physiological sleep measures. Elucidating both the neurobiological and psychological correlates of PTSD-related sleep disturbances is critical for developing future targeted intervention efforts aimed at reducing the burden of PTSD.
