title: Psychometric properties of the anxiety sensitivity index-3 in an acute and heterogeneous treatment sample.
abstract: Anxiety sensitivity (AS) is associated with various forms of psychopathology. The most common measure of AS is the anxiety sensitivity index-3 (ASI-3). The current study examined the psychometric properties and factor structure of the ASI-3 in an acute and comorbid population seeking treatment for a broad range of psychopathology (N=382). Results confirmed a bi-factor structure and suggested that the ASI-3 demonstrates adequate psychometric properties in a transdiagnostic sample. The ASI-3 also showed adequate sensitivity to change over the course of partial hospital treatment. Findings regarding associations between specific anxiety disorders and subscales of the ASI-3 are discussed. Overall, the current results support the use of the ASI-3 to assess AS in heterogeneous treatment-seeking samples. This work is of particular utility for researchers examining the concept of AS transdiagnostically.
