Emotion dysregulation is implicated in the development, maintenance, and treatment of sleep disturbances and posttraumatic stress disorder (PTSD) separately. However, few studies have assessed interactions among these variables. To address this gap, this study examined whether the associations of sleep quality and sleep quantity with PTSD severity were stronger at higher levels of negative and positive emotion dysregulation in a community sample of 199 trauma-exposed individuals. This study found that both poorer sleep quality and lower sleep quantity were associated with greater PTSD severity at low to average (but not high) levels of negative emotion dysregulation. Positive emotion dysregulation did not moderate the relationships between sleep quality or quantity and PTSD severity. Exploratory additive multiple moderation analyses showed significant associations between poorer sleep quality and lower sleep quantity with greater PTSD severity at low to average levels of negative emotion dysregulation, coupled with any level of positive emotion dysregulation. Findings inform theoretical perspectives on the sleep-PTSD relationship and clinical applications of targeting emotion dysregulation in the treatment of sleep disturbances and PTSD symptoms for trauma-exposed individuals.
情绪调节障碍与睡眠障碍和创伤后应激障碍（PTSD）的发生、维持和治疗都有关联。然而，很少有研究评估这些变量之间的相互作用。为了弥补这一空白，本研究在一个由 199 名创伤暴露个体组成的社区样本中，考察了在更高水平的负性和正性情绪调节障碍下，睡眠质量和睡眠数量与 PTSD 严重程度之间的关联是否更强。本研究发现，在低到中等（但不是高）水平的负性情绪调节障碍下，较差的睡眠质量和较低的睡眠量与更高的 PTSD 严重程度相关。正性情绪调节障碍不能调节睡眠质量或数量与 PTSD 严重程度之间的关系。探索性的附加多重调节分析表明，在低到中等水平的负性情绪调节障碍，以及任何水平的正性情绪调节障碍下，较差的睡眠质量和较低的睡眠量与更高的 PTSD 严重程度之间存在显著关联。研究结果为睡眠与 PTSD 关系的理论观点提供了信息，并为针对创伤暴露个体的睡眠障碍和 PTSD 症状的情绪调节障碍的治疗提供了临床应用。
