Factor analytic studies of the State—Trait Anxiety Inventory (STAI) have provided support for the concepts of state and trait anxiety. This article reports the factor structure of the STAI (Form X) using 205 panic‐disordered patients with and without agoraphobia. Results show that a two‐factor oblique solution is the most appropriate, accounting for 41.1 per cent of the variance. Eighteen of the A‐State items had salient loadings on factor 1 (state anxiety) and all 20 of the A‐Trait items had salient loadings on factor 2 (trait anxiety). This study demonstrates the utility of the STAI in measuring anxiety in clinical populations and further supports the theoretical distinction between state and trait anxiety.
