Psychometric properties of the Social Interaction Anxiety Scale and separation criterion between Spanish youths with and without subtypes of social anxiety.
In this study, we analyzed the reliability and validity of the Social Interaction Anxiety Scale (SIAS) and propose a separation criterion between youths with specific and generalized social anxiety and youths without social anxiety. A sample of 1012 Spanish youths attending school completed the SIAS, the Liebowitz Social Anxiety Scale, the Social Avoidance and Distress Scale, the Fear of Negative Evaluation Scale, the Youth Self-Report for Ages 11-18 and the Minnesota Multiphasic Personality Inventory-Adolescent. The factor analysis suggests the existence of three factors in the SIAS, the first two of which explain most of the variance of the construct assessed. Internal consistency is adequate in the first two factors. The SIAS features an adequate theoretical validity with the scores of different variables related to social interaction. Analysis of the criterion scores yields three groups pertaining to three clearly differentiated clusters. In the third cluster, two of social anxiety groups - specific and generalized - have been identified by means of a quantitative separation criterion.
