The Panic Appraisal Inventory: Psychometric properties

We examined the reliability and validity of the Panic Appraisal Inventory (PAI) in a sample of 47 outpatients with DSM-III-R panic disorder. Results showed excellent internal consistency and treatment sensitivity. We found good convergent validity; divergent validity vis-à-vis depression and social adjustment was adequate. Taken together, the current results provide good initial support for the reliability and validity of the PAI, though tests of the instrumentʹs factorial validity, stability over time, and criterion-related validity have yet to be conducted.
