This study evaluated anxiety sensitivity, cognitive avoidance, and alexithymia and their relationship to posttraumatic stress disorder (PTSD) and alcohol use indices concurrently and prospectively in an outpatient substance abuse treatment sample that screened positive for PTSD ( N = 58). Anxiety sensitivity accounted for substantial variance in the PTSD clusters, reexperiencing, avoidance, and hyperarousal, both concurrently and prospectively. Cognitive avoidance accounted for additional variance with concurrent PTSD avoidance symptoms. Anxiety sensitivity and cognitive avoidance were largely not associated with alcohol use indices. Alexithymia was largely redundant with cognitive avoidance and was, therefore, not included in the regression analyses. Theoretical and treatment implications of these findings are discussed in the context of individuals with dually diagnosed PTSD and substance abuse disorders.
