越来越多的文献表明，高焦虑敏感度(AS；对焦虑及其相关后果的恐惧)/低痛苦耐受性(DT；容忍内部负面状态的能力)与创伤后应激障碍(PTSD)症状之间存在关系。然而，在退伍军人样本中还没有确定或具体检查特定的特征。因此，本研究的目的是建立从焦虑敏感指数和痛苦耐受量表上的反应模式创建的经验性派生简档，并在战斗暴露的退伍军人样本(N=1250)中检查与创伤后应激障碍症状群的相关性。采用聚类分析方法识别AS/DT图谱，并进行一系列多变量方差分析和事后分析，以检验每个AS/DT图谱与每个PTSD症状群之间的关系。结果表明，三群集解决方案包括高AS/低DT“风险”配置文件、低AS/高DT“弹性”配置文件和平均AS/DT“中等”配置文件。与其他两个特征相比，高危特征与每个创伤后应激障碍集群中明显更严重的症状(即过度唤醒、回避、再次经历)相关。高危人群还与更严重的抑郁症状和较低的自我报告韧性有关。这些发现扩展了先前的文献，确定了高AS/低DT“风险”特征及其与创伤后应激障碍症状的关联，强调了针对这些情感调节结构进行临床干预的潜在效用。
A growing literature suggests a relationship between a high anxiety sensitivity (AS; the fear of anxiety and its related consequences)/low distress tolerance (DT; the capacity tolerate internal negative states) profile and posttraumatic stress disorder (PTSD) symptoms. However, specific profiles have not been identified or examined specifically in Veteran samples. Thus, the aims of the present study were to establish empirically derived profiles created from response patterns on the Anxiety Sensitivity Index and Distress Tolerance Scale and to examine associations with PTSD symptom clusters among a sample of combat-exposed Veterans (N= 250). A cluster analytic approach was used to identify AS/DT profiles, and a series of multivariate analyses of variance with post hoc analyses was conducted to examine the relationship between each AS/DT profile and each PTSD symptom cluster. Results indicated a 3-cluster solution including a high AS/low DT “at risk” profile, a low AS/high DT “resilient” profile, and an average AS/DT “intermediate” profile. The at-risk profile was associated with significantly greater symptoms in each PTSD cluster (i.e., hyperarousal, avoidance, re-experiencing) when compared to the other two profiles. The at-risk profile was also associated with greater depressive symptoms and lower self-reported resilience. These findings extend the previous literature by identifying a high AS/low DT “at risk” profile and its associations with PTSD symptoms, underscoring the potential utility in targeting these affect-regulation constructs for clinical intervention.
