Psychometric evaluation of the Social Anxiety Scale for Adolescents and the Social Phobia and Anxiety Inventory for Children: construct validity and normative data.

This study evaluated the psychometric properties of the Social Anxiety Scale for Adolescents (SAS-A) and Social Phobia and Anxiety Inventory for Children (SPAI-C) in a sample of 1147 adolescents aged 13-17 years. The fit indices of confirmatory factor analyses were comparable to those obtained in prior studies and supported the hypothesized models of the SAS-A and SPAI-C. The internal consistency was good and 12-month test-retest reliability modest for both measures. A significant, positive correlation was found between the SAS-A and SPAI-C, showing that these measures assess related, but relatively independent constructs of social anxiety and phobia. These findings support the use of the SAS-A and SPAI-C with adolescents.
