It is well-established that adults with elevated psychiatric symptoms or a psychiatric disorder (e.g. depression) engage in lower amounts of physical activity (PA) compared to adults with fewer symptoms/no diagnosis. However, less is known about the association between psychiatric symptoms and PA behaviour in trauma-exposed adults. Most prior investigations have focused on independent associations between overall depression or posttraumatic stress disorder (PTSD) symptoms in relation to PA and have neglected specific symptom domains (e.g. anhedonia). Therefore, we conducted secondary analyses on a parent dataset to examine whether PTSD symptom severity moderates the association between anhedonia and PA volume. Trauma-exposed adults ( = 107, 61% women, M ± SD age = 28 ± 9 y 54% White) completed questionnaires assessing demographic information, anhedonia, PTSD symptom severity (overall and symptom clusters), and PA volume (total MET-min/week). Main effects and interactions between anhedonia and PTSD symptom severity in relation to PA volume were examined with robust linear regression models. We observed a significant anhedonia × PTSD symptom severity interaction. An inverse association between anhedonia and PA volume was observed among adults with lower-to-moderate PTSD symptom severity, and a positive association between anhedonia and PA volume was observed among adults with higher PTSD symptom severity. Significant anhedonia × PTSD symptom severity interactions for avoidance (Cluster C) and negative alterations in arousal/reactivity (Cluster E) symptoms were also observed, with associations in the same direction as the overall PTSD symptom severity model. These preliminary findings suggest that co-occurring anhedonia and PTSD symptom severity profiles interact to influence PA volume in trauma-exposed adults. Future research is needed to understand why trauma-exposed adults with greater co-occurring anhedonia and PTSD symptom severity profiles reported engaging in higher levels of PA compared to those with lower symptom severity profiles. Such knowledge could help healthcare practitioners tailor treatment plans to incorporate or adjust PA prescriptions.
与症状较少/未确诊的成年人相比，有精神症状或精神障碍（如抑郁症）的成年人进行的身体活动（PA）量较低，这一点已得到充分证实。然而，对于遭受创伤的成年人而言，精神症状与PA行为之间的关联却鲜为人知。大多数先前的研究都集中在总体抑郁或创伤后应激障碍（PTSD）症状与PA之间的独立关联上，而忽略了特定的症状领域（如快感缺乏）。因此，我们对一个母数据集进行了二次分析，以检验PTSD症状严重程度是否会调节快感缺乏与PA量之间的关联。遭受创伤的成年人（n = 107，61%为女性，平均年龄±标准差 = 28±9岁，54%为白人）完成了问卷调查，评估人口统计学信息、快感缺乏、PTSD症状严重程度（总体和症状簇）以及PA量（每周总代谢当量分钟数）。使用稳健线性回归模型检验快感缺乏与PTSD症状严重程度在PA量方面的主效应和交互作用。我们观察到显著的快感缺乏×PTSD症状严重程度交互作用。在PTSD症状严重程度较低至中等的成年人中，观察到快感缺乏与PA量之间呈负相关；在PTSD症状严重程度较高的成年人中，观察到快感缺乏与PA量之间呈正相关。对于回避（C簇）和唤醒/反应性负面改变（E簇）症状，也观察到显著的快感缺乏×PTSD症状严重程度交互作用，其关联方向与总体PTSD症状严重程度模型相同。这些初步发现表明，同时出现的快感缺乏和PTSD症状严重程度特征相互作用，影响遭受创伤成年人的PA量。未来需要进行研究，以了解为什么同时出现快感缺乏和PTSD症状严重程度较高的遭受创伤成年人报告的PA水平高于症状严重程度较低的成年人。这些知识可以帮助医疗从业者调整治疗计划，以纳入或调整PA处方。
