The association between anxiety sensitivity (AS) and posttraumatic stress disorder (PTSD) has been established in contemporary literature; however, research is divided over the nature of specific relationships between AS dimensions and PTSD symptoms clusters. Further, a paucity of research has examined the AS and PTSD relationship while accounting for theoretically relevant variables, such as negative (NA) and positive affect (PA). The purpose of the current study was twofold: first, to clarify divergent findings regarding the contribution of AS dimensions to PTSD symptom clusters, and, second, to further assess the relevance of NA and PA within the AS/PTSD relationship. Hierarchal regression analyses showed that, beyond shared variance attributable to NA and PA, AS somatic concerns were significantly associated with three of four PTSD symptom (i.e., reexperiencing, numbing, hyperarousal), AS cognitive concerns were only associated with hyperarousal, and AS socially observable symptoms were not significantly associated with any PTSD symptom clusters. These findings suggest that AS somatic concerns are the most robust predictor of variance within the AS/PTSD relationship and further clarify the theoretical importance of NA and PA within this relationship. Comprehensive results, implication, and directions for future research are discussed.
焦虑敏感 (AS) 与创伤后应激障碍 (PTSD) 之间的关联在当代文献中已经确立；然而，研究在 AS 维度与 PTSD 症状群之间的特定关系的性质上存在分歧。此外，很少有研究在考虑到理论相关变量（如负性 (NA) 和正性 (PA) 时），同时考虑到理论相关变量（如负性 (NA) 和正性 (PA) 时），研究 AS 和 PTSD 之间的关系。本研究的目的有两个：首先，阐明关于 AS 维度对 PTSD 症状群的贡献的不同发现；其次，进一步评估 NA 和 PA 在 AS/PTSD 关系中的相关性。层次回归分析表明，除了可归因于 NA 和 PA 的共同方差外，AS 躯体担忧与 PTSD 症状的三个（即再体验、麻木、警觉过度）显著相关，AS 认知担忧仅与警觉过度相关，而 AS 社会可观察症状与任何 PTSD 症状群均无显著相关性。这些发现表明，AS 躯体担忧是 AS/PTSD 关系中变异的最有力预测因素，并进一步阐明了 NA 和 PA 在这种关系中的理论重要性。全面的结果、影响和未来研究方向进行了讨论。
