Abstract

The Work and Social Adjustment Scale (WSAS) is a brief global measure of functional impairment that is widely used in adult health. We have adapted the WSAS for its use in youth, the WSAS-Youth version (WSAS-Y) and WSAS-Parent version (WSAS-P). This study evaluated the psychometric properties of the scale. The internal consistency, factor structure, convergent and divergent validity, test–retest reliability and sensitivity to change of the WSAS-Y/P were studied in 525 children and adolescents with obsessive–compulsive disorder and related disorders receiving treatment. The internal consistency of the WSAS-Y/P was excellent across diagnostic groups and time-points. Exploratory factor analysis extracted a single-factor of functional... (More)

The Work and Social Adjustment Scale (WSAS) is a brief global measure of functional impairment that is widely used in adult health. We have adapted the WSAS for its use in youth, the WSAS-Youth version (WSAS-Y) and WSAS-Parent version (WSAS-P). This study evaluated the psychometric properties of the scale. The internal consistency, factor structure, convergent and divergent validity, test–retest reliability and sensitivity to change of the WSAS-Y/P were studied in 525 children and adolescents with obsessive–compulsive disorder and related disorders receiving treatment. The internal consistency of the WSAS-Y/P was excellent across diagnostic groups and time-points. Exploratory factor analysis extracted a single-factor of functional impairment, explaining in excess of 85% of the variance. The test–retest reliability was adequate. The WSAS-Y/P correlated more strongly with other measures of functional impairment than with measures of symptom severity, indicating good convergent/divergent validity. Finally, the WSAS-Y/P was highly sensitive to change after treatment.
