title: Anxiety sensitivity and posttraumatic stress among traumatic event-exposed youth.
abstract: Total and factor scores of the Childhood Anxiety Sensitivity Index (CASI) were examined in relation to posttraumatic stress symptom levels within a community-based sample of 68 (43 females) traumatic event-exposed youth between the ages of 10 and 17 years (M age=14.74 years). Findings were consistent with hypotheses; global anxiety sensitivity (AS) levels, as well as disease, unsteady, and mental incapacitation concerns, related positively to posttraumatic stress levels, whereas social concerns were unrelated to symptom levels. These results suggest that fears of the physical and mental consequences of anxiety are associated with relatively higher levels of posttraumatic stress subsequent to traumatic event exposure. Findings are discussed in terms of potential implications for the role of AS in developmentally sensitive etiological models of posttraumatic stress disorder (PTSD).
