A Comparison of Social Phobia Outcome Measures in Cognitive-Behavioral Group Therapy

This article reports the effects of a cognitive-behavioral group therapy program for social phobia (N = 25 outpatients) on several psychometric measures. It is the first study to simultaneously examine three newer and promising social-phobia measures: the Social Phobia Scale (SPS) and accompanying Social Interaction Anxiety Scale (SIAS), the Social Phobia and Anxiety Inventory (SPAI), and the Liebowitz Social Anxiety Scale (LSAS). More traditional measures of social phobia were also included, along with measures of anxious and depressed mood. Among the newer scales, the SPAI and SPS/SIAS were found to have good sensitivity to treatment. There was limited support for the LSAS. Intercorrelations among all of the outcome measures are presented both before and after cognitive-behavioral therapy. Strengths and weaknesses of each of the newer social-phobia measures are discussed.
