Psychometric evaluation of the Social Phobia and Anxiety Inventory in college students.

The present study reports on the psychometric properties of the Social Phobia and Anxiety Inventory (SPAI; Turner et al., 1989a) in two nonclinical samples of college undergraduates. Exploratory principal-components analysis with varimax rotation replicated the five-factor solutions reported for the 32-item Social Phobia subscale (SP) in sample 1 (N = 200). Confirmatory factor analyses showed that the five-factor structure of the SP and the two-factor structure of the SPAI were appropriate for the second sample (N = 210) data. Coefficient alpha values were high for all the SP and the SPAI subscales. Furthermore, we examined the relations between the SPAI subscales and measures of social fear and anxiety, social desirability, and general psychopathology. Results support the research use of the SPAI in our undergraduate samples.
