In this study the concurrent validity of the Assessment of Occu ational Functioning (AOF) (1st rev.) (Brollier&Watts, 1985; katts, Kielhofner, Bauer, Gregory,&Valentine, 1986) and the Occupational Case Anal sis and Interview Ratin Scale (OCAIRS) (Kaplan, 1983,1984; d p l a n&Kielhober, 1 9 8 8 was assessed, using scores on the Global Assessment Scale (Endicott, Spitzer, Fleiss,&Cohen, 1976), a well-known measure of psychosocial health-illness. Forty-one chronic schizophrenic sub-jects were tested with these three measures. Both the AOF and the OCAIRS were found to have adequate concurrent validity.
