Abstract

BACKGROUND:

Patients' perspectives concerning impaired functioning provide important information. AIMS; To evaluate the reliability and validity of the Work and Social Adjustment Scale (WSAS).

METHOD:

Data from two studies were analysed. Reliability analyses included internal scale consistency, test-retest and parallel forms. Convergent and criterion validities were examined with respect to disorder severity.

RESULTS:

Cronbach's alpha measure of internal scale consistency ranged from 0.70 to 0.94. Test-retest correlation was 0.73. Interactive voice response administrations of the WSAS gave correlations of 0.81 and 0.86 with clinician interviews. Correlations of WSAS with severity of depression and obsessive-compulsive disorder symptoms were 0.76 and 0.61, respectively. The scores were sensitive to patient differences in disorder severity and treatment-related change.

CONCLUSIONS:

The WSAS is a simple, reliable and valid measure of impaired functioning. It is a sensitive and useful outcome measure offering the potential for readily interpretable comparisons across studies and disorders.
