Psychometric properties of the Social Phobia and Anxiety Inventory for Children using a non-American population-based sample.
Although previous studies have examined the factor structure of the SPAI-C, adequate factor analytic methodology has not been employed. This study explored the psychometric properties of the Social Phobia and Anxiety Inventory for Children (SPAI-C), using a non-American population-based sample of older children and young adolescents 11-14 years of age. Initially an exploratory factor analysis was conducted followed 1 year later by a confirmatory factor analysis. Five factors labeled Assertiveness, Public Performance, Physical/Cognitive Symptoms, Social Encounter, and Avoidance were retained and confirmed. The Public Performance and Assertiveness factors were the most stable and consistent factors or traits of social anxiety over a 1-year period. Results revealed adequate concurrent validity, internal consistency and moderate 12-month test-retest reliability of the SPAI-C total scale. The SPAI-C was found to assess levels of both social anxiety and social anxiety disorder according to DSM-IV criteria. Findings suggest that the SPAI-C is applicable in clinical treatment studies designed to assess sensitivity to change in various aspects of social anxiety disorder.
