The social phobia and anxiety inventory: Further validation in two nonclinical samples

The Social Phobia and Anxiety Inventory (SPAI) has been developed to assess specific symptoms of social phobia and agoraphobia. Although the SPAI was developed with both clinical and nonclinical populations, research with this measure is currently focused primarily on clinical samples. We examined the factor structure and psychometric properties of the SPAI in adult community and college undergraduate samples. We found that single-sample and multisample confirmatory factor analyses provided support for extending use of the correlated two-factor SPAI subscales to our nonclinical samples. In addition, we found evidence for the internal consistency reliability of the SPAI subscales in both samples. Limitations and suggestions for future research are discussed.
