The present investigation examined the main and interactive effects of anxiety sensitivity and behavioral distress tolerance, indexed using the breath-holding task, in relation to PTSD symptom severity among trauma-exposed adults. Participants were 88 adults (63.6% women; M(age)=22.9, SD=9.1, range=18-62), recruited from the community, who met DSM-IV-TR PTSD Criterion A for lifetime trauma exposure. Covariates included number of potentially traumatic events, nonclinical panic attack history, and participant sex. Anxiety sensitivity was significantly incrementally associated with PTSD total symptom severity, as well as Avoidance and Hyperarousal symptom severity (p's<.01). Breath-holding duration was not significantly related to PTSD symptom severity (p's>.05). However, breath-holding duration emerged as a significant moderator of the association between anxiety sensitivity and PTSD Avoidance symptom severity, such that lower breath-holding duration exacerbated the effect of heightened anxiety sensitivity with regard to PTSD Avoidance symptom severity.
本研究考察了焦虑敏感和行为困扰容忍度（通过屏息任务来衡量）在创伤后应激障碍症状严重程度方面的主要和交互作用，研究对象为 88 名来自社区的成年人（63.6%为女性；M（年龄）=22.9，SD=9.1，范围 18-62），他们符合 DSM-IV-TR 创伤后应激障碍 A 类终生创伤暴露标准。协变量包括潜在创伤事件的数量、非临床惊恐发作史和参与者性别。焦虑敏感与 PTSD 总症状严重程度以及回避和过度警觉症状严重程度呈显著递增相关（p<.01）。屏息时间与 PTSD 症状严重程度无显著相关（p>.05）。然而，屏息时间是焦虑敏感与 PTSD 回避症状严重程度之间关联的一个显著调节因素，即较低的屏息时间加剧了焦虑敏感对 PTSD 回避症状严重程度的影响。
