The current study examined the mediating role of anxiety sensitivity in regard to the relation between avoidant coping and posttraumatic stress (PTS) symptoms among trauma-exposed persons living with HIV/AIDS (PLHA). Participants included 103 PLHA (18.4% female, Mage = 48.33, SD = 9.34). Results indicated significant positive indirect effects for avoidant coping through anxiety sensitivity on overall PTS symptoms (point estimate = .27, PB 95% CI [.01, .65]), PTS hyperarousal symptoms (point estimate = .09, PB 95% CI [.01, .21]), and PTS avoidant symptoms (point estimate = .14, PB 95% CI [.03, .30]). The observed findings were statistically significant and evident above and beyond the variance accounted for by CD4 cell count, race, sex, recruitment site, and lifetime number of traumatic events experienced. The results may indicate that avoidant coping affects PTS symptoms through anxiety sensitivity among trauma-exposed PLHA. These findings highlight the importance of anxiety sensitivity in relation to PTS symptoms among PLHA, and the possibility of adapting anxiety sensitivity reduction training for PTS symptoms among PLHA.
本研究考察了焦虑敏感性在创伤后应激障碍（PTS）症状与回避应对之间的中介作用，探讨了艾滋病毒/艾滋病感染者（PLHA）中的关系。参与者包括 103 名 PLHA（18.4%为女性，Mage = 48.33，SD = 9.34）。结果表明，回避应对通过焦虑敏感性对总体 PTS 症状（点估计值= 0.27，95%置信区间[0.01，0.65]）、PTS 警觉症状（点估计值= 0.09，95%置信区间[0.01，0.21]）和 PTS 回避症状（点估计值= 0.14，95%置信区间[0.03，0.30]）具有显著的正向间接影响。观察到的发现具有统计学意义，且明显超出了 CD4 细胞计数、种族、性别、招募地点和经历的创伤性事件数量的方差解释。结果可能表明，回避应对通过创伤后 PLHA 中的焦虑敏感性影响 PTS 症状。这些发现突出了焦虑敏感性与 PLHA 中 PTS 症状之间的关系的重要性，以及为 PLHA 中的 PTS 症状改编焦虑敏感性降低训练的可能性。
