The current study tested whether emotion dysregulation, assessed by the Difficulties in Emotion Regulation Scale (DERS), would predict posttraumatic stress symptoms (PTSS) through anxiety sensitivity (AS). Alternate cognitive-affective mediators (i.e., distress tolerance and intolerance of uncertainty) were explored.
A total of 259 trauma-exposed community members (ages averaging 37.39; evenly distributed by gender) from a larger clinical trial targeting suicide risk factors completed a clinical interview and self-report questionnaires at baseline, Week-3, and 1-month follow-up appointments.
AS at Week 3 significantly mediated the relationship between initial emotion dysregulation and 1-month follow-up posttraumatic stress symptoms (PTSS) after controlling for condition and baseline symptoms (β = .07; standard error = 0.03; 95% confidence interval = [0.01, 0.14]). Effects held for one out of six emotion dysregulation subscales. Distress tolerance and intolerance of uncertainty were not significant mediators (ps > .05).
This study demonstrates that emotion dysregulation may confer maintenance of PTSS through AS. Findings highlight potentially malleable targets for interventions.
本研究通过焦虑敏感（AS）检验情绪调节困难量表（DERS）评估的情绪失调是否通过焦虑敏感预测创伤后应激症状（PTSS）。还探讨了替代的认知-情感中介因素（即痛苦耐受力和不确定性容忍度）。
共有 259 名来自更大规模针对自杀风险因素的临床试验的创伤暴露社区成员（平均年龄 37.39 岁，性别分布均匀）在基线、第 3 周和 1 个月随访预约时完成了临床访谈和自我报告问卷。
在控制条件和基线症状后，第 3 周的 AS 显著中介了初始情绪失调与 1 个月随访时创伤后应激症状（PTSS）之间的关系（β=0.07；标准误差=0.03；95%置信区间=[0.01, 0.14]）。这一结果适用于六个情绪失调子量表中的一个。痛苦耐受力和不确定性容忍度不是显著的中介因素（p>.05）。
这项研究表明，情绪失调可能通过焦虑敏感导致创伤后应激症状的持续存在。研究结果强调了干预的潜在可调整目标。
