Abstract

The Spence Children’s Anxiety Scale (SCAS) has demonstrated good psychometric properties in several countries and cultures. Nevertheless, most of the previous studies that explore these properties have combined clinical and community samples. We aimed to validate the Spanish version of the SCAS in a large clinical sample (N = 130) of children and adolescents. The Spanish adaptation of the SCAS showed good internal consistency for the total scale, and good test-retest reliability for all the subscales. Furthermore, its convergent and discriminant validity were supported by significant correlations with other anxiety questionnaires (Screen for Child Anxiety Related Emotional Disorders [SCARED], Youth Self-Report [YSR] subscales for anxiety disorders and internalizing symptomatology), and lower or non-significant correlations with depression symptoms and externalizing symptoms scales respectively. For the first time in a purely clinical sample, the original factor structure of the SCAS based on six correlated factors was confirmed. Future studies need to evaluate whether the factorial structure of the present instrument is the most suitable for use in clinical populations.
