ABSTRACT

The association between distress tolerance (DT) and posttraumatic stress disorder (PTSD) is well established. This study aimed to provide an account of the magnitude of this effect across available studies. From the 2,212 records yielded by the initial search, 56 studies comprised 12,672 participants (M_age = 29.96, SD = 12.05; 44.94% women) were included in the investigation upon a priori criteria. Results demonstrated consistent negative associations between DT and PTSD symptoms, such that lower DT was associated with higher PTSD symptom severity and vice versa; the effect size (ES) was relatively small in magnitude (r = −0.335, 95% CI [−0.379, −0.289]). Moreover, ESs for the DT-PTSD association were significantly greater for studies which examined self-reported DT compared to those that examined behavioral DT. The number of traumatic event types experienced (trauma load) was the most consistent moderator of the DT and PTSD association. The clinical implications of the role of DT in PTSD are discussed.

摘要

痛苦耐受 (DT) 和创伤后应激障碍 (PTSD) 之间的关联已经确立。本研究旨在说明现有研究中这种影响的程度。从最初搜索产生的 2,212 条记录中，56 项研究包括 12,672 名参与者（M_年龄 =  29.96，SD  = 12.05；44.94% 女性）根据先验标准纳入调查。结果表明 DT 和 PTSD 症状之间存在一致的负相关关系，因此较低的 DT 与较高的 PTSD 症状严重程度相关，反之亦然；效应大小 (ES) 在量级上相对较小(r = -0.335, 95% CI [-0.379, -0.289])。此外，与检查行为 DT 的研究相比，检查自我报告 DT 的研究的 DT-PTSD 关联的 ES 显着更高。经历的创伤事件类型（创伤负荷）的数量是 DT 和 PTSD 关联最一致的调节因子。讨论了 DT 在 PTSD 中的作用的临床意义。
