Validation of the Spanish Version of the Work and Social Adjustment Scale in a Sample of Individuals With Bipolar Disorder.

The aim of the current study was to validate the Work and Social Adjustment Scale (WSAS), a measure of psychosocial functional impairment, in Spanish-speaking individuals with bipolar disorder. A sample of 120 patients with bipolar disorder and 97 healthy individuals completed the WSAS to analyze its factor structure and reliability. Patients also completed measures of personal recovery and quality of life (QOL). Confirmatory factor analysis indicated that a one-factor model explained data adequately, with all factor loadings proving to be significant. Cronbach's alphas indicated excellent internal consistency in the sample of individuals with bipolar disorder and the sample of healthy individuals. Significant negative correlations between the WSAS and personal recovery and QOL demonstrated good concurrent validity. Impairment on the WSAS was higher for the patient sample, confirming known-group validity of the scale. Thus, Spanish validation of the WSAS demonstrated it to be a sound self-reported measure of psychosocial functioning impairment in individuals with bipolar disorder.
