Psychometric properties of the Social Phobia and Anxiety Inventory, the Social Anxiety Scale for Adolescents, the Fear of Negative Evaluation Scale, and the Social Avoidance and Distress Scale in an adolescent Spanish-speaking sample

The relationship among several social anxiety measures and a semistructured interview in an adolescent Spanish-speaking sample is examined. Construct validity and test-retest reliability were tested. A principal axis factor analysis was also explored. Results revealed good construct validity and alpha coefficients for the assessment instruments such as the Social Phobia and Anxiety Inventory (SPAI), the Social Anxiety Scale for Adolescents (SAS-A), the Fear of Negative Evaluation Scale (FNES) and the Social Avoidance Distress Scale (SADS). Among these, data strongly support the validity of the Social Phobia and Difference measures of the SPAI and Total SAS-A score as assessment measures in the adolescent population even in non-American cultures and languages. Furthermore, results appear to support the presence of a single higher-order dimension, "social anxiety," as measured by the instruments used in this study.
