VALIDATION OF THE SPANISH VERSION OF THE ANXIETY SENSITIVITY INDEX INA CLINICAL-SAMPLE

In this study we validated the Spanish version of the Anxiety Sensitiv ity Index (ASI) in a sample of anxiety disordered patients. The result s revealed that: (1) ASI scores were higher for anxiety disordered pat ients than for normal control subjects, and higher for patients with p anic disorder (PD) than for patients with other anxiety disorders (OAD ). In contrast, there were no differences among the groups on the Cogn itive-Somatic Anxiety Questionnaire (CSAQ). (2) Using discriminant ana lysis, we were able to differentiate PD patients from patients with OA D on the ASI, but no: on the CSAQ. (3) Results supported a unidimensio nal factor-structure for the ASI. (4) Data provide cross-cultural evid ence for construct validity and concurrent validity of the Spanish ASI , and provide further evidence for the usefulness of the concept of an xiety sensitivity.
