The psychometric properties of a Catalan version of the Spence Children’s Anxiety Scale, SCAS (Spence, 1998) were analyzed in a sample of 692 elementary-school children. The Catalan SCAS demonstrated high internal consistency, test-retest reliability, convergent and discriminant validity, similar to previous results with the English version. A principal component analysis of the instrument yielded six factors, slightly different from previous research. The similarity of the findings to previous research on the SCAS is discussed.
