ABSTRACT

Despite the promise of past research on anxiety sensitivity (AS) and posttraumatic stress, extant work is limited, given (1) most studies consist of non-Hispanic White and middle-aged samples, (2) few have demonstrated incremental validity to general emotional traits and social determinants of health, and (3) limited work has characterized how AS relates to specific Posttraumatic Stress Disorder (PTSD) symptom clusters among those with (probable) PTSD. The current study evaluated the role of AS in relation to PTSD symptom clusters among a racially/ethnically diverse sample of young adults with probable PTSD. Participants included young adults who met the clinical cut-off for probable PTSD per the Posttraumatic Diagnostic Scale. Results indicated that AS was significantly related to overall posttraumatic stress symptom severity; the effect was evident after adjusting for a range of covariates including neuroticism and subjective social status. AS also was incrementally associated with arousal and hyperreactivity, changes in mood and cognition, and intrusion PTSD symptom clusters. In contrast to expectation, no effect for AS was evident for the avoidance PTSD symptom cluster. The current data uniquely add to the existing AS PTSD literature by showcasing distinct symptom cluster patterns among a racially/ethnically diverse sample of young adults with probable PTSD.

摘要

尽管过去对焦虑敏感性 (AS) 和创伤后压力的研究很有希望，但现存的工作是有限的，因为 (1) 大多数研究由非西班牙裔白人和中年样本组成，(2) 很少有人证明对一般情绪的有效性增加特征和健康的社会决定因素，以及 (3) 有限的工作描述了 AS 如何与（可能）PTSD 患者中的特定创伤后应激障碍 (PTSD) 症状群相关。目前的研究评估了 AS 在可能患有 PTSD 的年轻人的种族/族裔多样化样本中与 PTSD 症状群相关的作用。参与者包括根据创伤后诊断量表达到可能 PTSD 临床临界值的年轻人。结果表明，AS 与总体创伤后应激症状严重程度显着相关；在调整了一系列协变量（包括神经质和主观社会地位）后，效果很明显。AS 也逐渐与觉醒和过度反应、情绪和认知的变化以及侵入性 PTSD 症状群相关。与预期相反，回避 PTSD 症状群对 AS 没有明显影响。当前的数据通过在可能患有 PTSD 的年轻人的种族/族裔多样化样本中展示不同的症状集群模式，独特地添加到现有的 AS PTSD 文献中。对于回避 PTSD 症状群，AS 没有明显影响。当前的数据通过在可能患有 PTSD 的年轻人的种族/族裔多样化样本中展示不同的症状集群模式，独特地添加到现有的 AS PTSD 文献中。对于回避 PTSD 症状群，AS 没有明显影响。当前的数据通过在可能患有 PTSD 的年轻人的种族/族裔多样化样本中展示不同的症状集群模式，独特地添加到现有的 AS PTSD 文献中。
