Polish Adaptation and Psychometric Validation of the Anxiety Sensitivity Index-III

The present study sought to adapt and validate the psychometric properties of the Anxiety Sensitivity Index-III in Poland. The ASI-III consists of three subscales, each representing one of the three domains of fears of the negative consequences of anxiety-related physical, cognitive, or social sensations. The study included a total of 116 panic disorder patients and 411 controls who did not show the presence of mental disorders. The results indicated that the Polish-language version of the ASI-III is characterized by high content validity, internal consistency, and stability over a period of 28 days. Moreover, its factor structure was largely equivalent to that found on the original ASI-III.
