OBJECTIVES
Posttraumatic stress disorder (PTSD) severity relates to positive memory retrieval difficulties. One variable potentially influencing this relation is sleep difficulties. We examined moderating effects of sleep difficulties (duration and quality) on relations between PTSD severity and count of specific positive memories covarying for age, gender, and depression.
METHODS
Participants were an Amazon Mechanical Turk-recruited trauma-exposed community sample of 205 respondents (M = 35.44; 61.40% women).
RESULTS
Moderated regression analyses indicated significant interaction effects between sleep quality (b = 0.03; p = 0.036) and PTSD severity on specific positive memory count. Among individuals reporting better sleep quality, there were negative associations between PTSD severity and specific positive memory count (b = -0.04, SE = 0.02, p = 0.010). Similar results were obtained for PTSD's intrusion and arousal clusters.
CONCLUSION
Results support targeting sleep quality and PTSD severity to improve positive memory retrieval in PTSD and memory interventions, and the importance of considering sleep when examining links between PTSD and positive memory retrieval.
目的
创伤后应激障碍（PTSD）的严重程度与积极记忆检索困难有关。一个潜在影响这种关系的变量是睡眠困难。我们研究了睡眠困难（持续时间和质量）对 PTSD 严重程度与特定积极记忆数量之间关系的调节作用，这些记忆数量考虑了年龄、性别和抑郁因素。
方法
参与者是来自亚马逊 Mechanical Turk 的创伤暴露的社区样本，共 205 名受访者（M = 35.44；61.40%为女性）。
结果
调节回归分析表明，睡眠质量（b = 0.03；p = 0.036）和 PTSD 严重程度对特定积极记忆数量的交互作用显著。在报告睡眠质量较好的个体中，PTSD 严重程度与特定积极记忆数量之间存在负相关（b = -0.04，SE = 0.02，p = 0.010）。PTSD 的侵入和唤醒聚类也得到了类似的结果。
结论
结果支持针对睡眠质量和 PTSD 严重程度来改善 PTSD 中的积极记忆检索和记忆干预，以及在研究 PTSD 与积极记忆检索之间的联系时考虑睡眠的重要性。
