Abstract
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.
Notes
1. To be thorough, an independent samples t test was conducted to compare each of the measure subscale scores for men and women. Only PCL-C avoidance [t (309) = − 3.68, p < .01 (two tailed)] and hyperarousal [t (309) = − 3.13, p < .01 (two tailed)] were observed to be significantly different between men and women. The magnitude of the differences in the means was small (η2 = .04 for PCL-C avoidance and η2 = .03 for PCL-C hyperarousal).
