Convergent, discriminant, and criterion-related validity of the Social Phobia and Anxiety Inventory

The psychometric properties of the Social Phobia Anxiety Inventory (SPAI) w ere assessed in a sample of participants who either had a primary diagnosis of social phobia or were normal volunteers. Positive evidence was obtained on the SPAI's concurrent and predictive convergent validity: it teas signi ficantly correlated with other measures of social anxiety obtained from sel f-report questionnaires of social impairment and with behavioral assessment measures administered im conjunction with a conversation role-play, includ ing measures of negative thinking, subjective anxiety, and self-perceived s kill and apparent nervousness. Discriminant validity was demonstrated by th e SPAI's significantly stronger relationship with public than private self- consciousness. There was no overlap in SPAI scores ipl the normal volunteer and socially phobic groups, demonstrating criterion-related validity (C) 2 000 Wiley-Liss, Inc.
