ASI-3: A new scale for the assessment of anxiety sensitivity

Abstract

The Anxiety Sensitivity Index—3 (ASI-3) is a new 18-item self-report multidimensional instrument de-signed to assess the three best replicated dimensions of anxiety sensitivity, i.e., Physical, Cognitive and Social Concerns (Taylor et al., 2007). In the present study we examined the factor structure, reli-ability, validity and normative data of the Spanish version of the ASI-R in a nonclinical sample of 582 undergraduates. Exploratory and confirmatory factor analyses indicate a hierarchical factor structure consisting of 3 lower-order factors and 1 higher-order factor; where the 3 primary factors were identical to the ones reported by Taylor et al. (2007). Data on reliability (internal consistency and test-retest) and validity (convergent and discriminant) show the ASI-3 to have sound psychometric properties. Normative ASI-3 data reveal that women scored higher than men on the ASI-3 Physical Concerns subscale and on the ASI-3 total score. Implications of these results on psychopathology and clinical psychology are discussed.
