title: Measuring social anxiety in college students: a comprehensive evaluation of the psychometric properties of the SPAI-23.
abstract: Social anxiety disorder (SAD) is 1 of the most prevalent psychological disorders, and among college students in particular, social anxiety has been associated with other problems such as substance use problems and increased vulnerability to other psychiatric disorders. The Social Phobia and Anxiety Inventory-23 (SPAI-23; Roberson-Nay, Strong, Nay, Beidel, & Turner, 2007) may be a useful, brief measure of problematic social anxiety in college students. Results from 4 studies (total n = 2,436) using the SPAI-23 with college student samples are presented. Scores on the SPAI-23 demonstrated strong convergent validity with other measures of social anxiety and discriminant validity as evidenced by lower correlations with measures of dissimilar constructs. Difference scores on the SPAI-23 also demonstrated adequate test-retest reliability over 5 ½ weeks (r = .72). Exploratory factor analysis suggested a two-factor structure: social anxiety and agoraphobia. Finally, differential item function analyses suggested that the items function similarly in men and women. In conclusion, the SPAI-23 demonstrated strong psychometric properties for use with college students.
