Abstract: Anxiety sensitivity is a transdiagnostic construct that has been associated with the etiology of emotional disorders, especially panic and other anxiety disorders. Although it is well known that, for the adult population, the factor structure of anxiety sensitivity includes three separate facets (physical, cognitive, and social concerns), the facets of anxiety sensitivity for adolescents have not yet been established. The main goal of the present study was to examine the factor structure of the Spanish version of the Childhood Anxiety Sensitivity Index (CASI). A large sample of nonclinical adolescents completed the Spanish version of the CASI in school settings ( N = 1655; aged 11–17 years; 800 boys and 855 girls). Exploratory and confirmatory factor analyses of the full scale (CASI-18) indicate that a three first-order factor solution represents appropriately the three anxiety sensitivity facets previously defined for the adult population. The 3-factor structure had a better fit and was more parsimonious than a 4-factor solution. Results also indicate that the 3-factor structure remains invariant across genders. Girls scored significantly higher than boys on the total scale and on all three dimensions of anxiety sensitivity. In addition, the present study provides information concerning normative data for the scale. The CASI holds promise as a useful tool for assessing general and specific facets of anxiety sensitivity. It could be helpful for the assessment of this construct in clinical and preventive settings. The limitations of the study and suggestions for further research are outlined.
