A meta-analysis of the cross-cultural psychometric properties of the Social Phobia and Anxiety Inventory for Children (SPAI-C)

Several studies have found that the Social Phobia and Anxiety Inventory for Children (SPAI-C), an empirically derived self-report instrument to assess DSM-IV social phobia in childhood and adolescence, has good psychometric properties. While these findings were replicated across different cultures, the overall strength of the psychometric properties of the SPAI-C remains unknown. We assessed the validity of the SPAI-C by meta-analytic techniques across studies collected from PubMed. PsycInfo and Eric databases, conducted in different countries, among subjects of different age, and sex. A total of 21 articles were retained, predominantly from Europe and North America. We found that the psychometric properties based on Cronbach alpha, mean score differences between sexes, and construct validity, were robust for the SPAI-C scale. Girls scored significantly higher than boys, and geographical differences played a moderating effect on sex-related score differences. These results further support the SPAI-C as an instrument to identify Social Phobia in youth. (C) 2011 Elsevier Ltd. All rights reserved.
