Abstract

Background: Research primarily in civilian samples supports bidirectional relations between daytime factors and trauma-related nightmare (TRN) reports. This study tested the relations of daytime negative affect and event-related stress with nightly occurrence and characteristics of TRNs in a sample of Veterans with and without posttraumatic stress disorder (PTSD).

Methods: We studied 27 U.S. combat-exposed Veterans who completed prompts across seven days of an ecological momentary assessment protocol, assessing daytime negative affect and event-related stress. Each morning they also reported whether they had a TRN and, if so, the level of disturbance and vividness.

Results: Over 100 morning reports were collected. Approximately half of this sample (55%) reported at least one TRN across the study week, with TRNs reported only by participants with current PTSD. In multilevel logistic regression models, higher average negative affect was associated with greater odds of having TRNs. While negative affect and event-related stress on a given day were not prospectively associated with TRNs later that night, a TRN occurrence was associated with greater next-day negative affect and event-related stress.

Conclusion: In contrast to findings found in civilian populations, daytime negative affect and stress during the day were not associated with subsequent TRN occurrences in this Veteran sample. Instead, there was evidence for a cumulative effect of negative affect on TRN occurrence, potentially driven by experiencing TRNs. Therefore, targeting TRNs specifically could have a positive impact on reducing this self-maintaining nightmare cycle.

在战斗暴露的退伍军人中,日常影响、压力和噩梦报告的生态瞬间评估。
背景:主要在平民样本中的研究支持白天因素与创伤相关噩梦(TRN)报告之间的双向关系。本研究以有创伤后应激障碍(PTSD)和无创伤后应激障碍(PTSD)的退伍军人为研究对象,考察了白天负性情绪和事件相关应激与夜间trn发生的关系及其特征。方法:我们研究了27名美国战斗暴露的退伍军人,他们完成了为期7天的生态瞬时评估方案,评估了白天的负面影响和事件相关压力。每天早上,他们还报告了自己是否有TRN,如果有,则报告了干扰程度和活跃程度。结果:共收集早报100余份。大约一半的样本(55%)在整个研究周内报告了至少一次TRN,只有当前患有PTSD的参与者报告了TRN。在多水平逻辑回归模型中,较高的平均负面情绪与较高的trn发生率相关。虽然某一天的负面情绪和事件相关压力与当晚晚些时候的TRN没有前瞻性关联,但TRN的发生与第二天更大的负面情绪和事件相关压力相关。结论:与在平民人群中发现的结果相反,在该退伍军人样本中,白天的负面情绪和白天的压力与随后的TRN发生无关。相反,有证据表明,负面影响对TRN发生的累积效应,可能是由经历TRN驱动的。因此,专门针对trn可能对减少这种自我维持的噩梦周期产生积极影响。
