The psychometric properties of the Social Phobia Anxiety Inventory (SPAI) were 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 was significantly correlated with other measures of social anxiety obtained from self‐report questionnaires of social impairment and with behavioral assessment measures administered in conjunction with a conversation role‐play, including measures of negative thinking, subjective anxiety, and self‐perceived skill and apparent nervousness. Discriminant validity was demonstrated by the SPAI's significantly stronger relationship with public than private self‐consciousness. There was no overlap in SPAI scores in the normal volunteer and socially phobic groups, demonstrating criterion‐related validity. Depression and Anxiety 11:10–14, 2000. © 2000 Wiley‐Liss, Inc
