Abstract We evaluated the Portuguese version of the Anxiety Sensitivity Index 3 (ASI–3–PT). Results of a confirmatory factor analysis (N = 603; 65.3% women, M age = 28.55, SD = 10.42) confirmed multidimensionality of the construct and the receiver operating characteristic confirmed the discriminant capacity of the measure between clinical and nonclinical samples.
