Abstract

Objective: Posttraumatic stress disorder (PTSD) has four symptom clusters: intrusion, avoidance, negative cognitions/mood, and hyperarousal. Little is known about the extent to which the intensity of the symptom clusters vary from moment-to-moment. Using an ecological momentary assessment methodology, this study examined within day variation in the four PTSD symptom clusters.

Methods: Participants with PTSD (N = 78) completed self-report assessments of 18 posttraumatic stress symptoms (PTSS) four times daily for 15 days. Linear mixed models and linear spline models examined how PTSS and each of the four PTSD symptom clusters varied across six daily time-blocks (0700, 1000, 1300, 1600, 1900, 2200).

Results: PTSS and each symptom cluster differed across the six time-blocks: PTSS, F(5, 345) = 10.06, p < .001; intrusion: 3.02, p < .05; avoidance: 11.31, p < .001; negative cognitions/mood: 7.42, p < .001; and hyperarousal: 9.34, p < .001. All symptom clusters were lowest at the first time-block with an overall increasing pattern across the six time-blocks. Knot analyses indicated maximum symptoms of intrusion at 1000, while maximum symptoms of avoidance, negative cognitions/mood, and hyperarousal occurred at 1300.

Conclusions: All four PTSD symptom clusters vary within a day, are lowest in the morning and peak at different times. Further study of the causes of this within day variation, including the neurobiological, psychological, behavioral, and lifestyle factors is important for understanding the mechanisms of and interventions for PTSD.

创伤后应激障碍症状群的日变异。

目的：创伤后应激障碍（PTSD）有四种症状群：入侵、逃避、消极认知/情绪和亢奋。对于症状集群的强度随时间变化的程度知之甚少。使用生态瞬时评估方法，本研究检查了四种PTSD症状群在一天内的变化。方法：78例创伤后应激障碍（PTSD）患者完成18项创伤后应激症状（PTSS）自我报告评估，每天4次，持续15天。线性混合模型和线性样条模型研究了PTSD和四种PTSD症状群在6个每日时间段（0700、1000、1300、1600、1900、2200）的变化。结果：PTSD及各症状类在6个时间段均存在差异：PTSS， F(5,345) = 10.06， p p p p p p结论：4种PTSD症状类在一天内均存在差异，上午最低，高峰时间不同。进一步研究这种日间变化的原因，包括神经生物学、心理、行为和生活方式因素，对于理解创伤后应激障碍的机制和干预措施非常重要。

期刊介绍： Internationally recognized, Psychiatry has responded to rapid research advances in psychiatry, psychology, neuroscience, trauma, and psychopathology. Increasingly, studies in these areas are being placed in the context of human development across the lifespan, and the multiple systems that influence individual functioning. This journal provides broadly applicable and effective strategies for dealing with the major unsolved problems in the field.
