Abstract
Since the Global Assessment of Functioning Scale (GAF) was introduced in DSM-III-R in 1987, it has been widely used, but minimally researched. This report provides information concerning the use of the GAF in routine clinical practice. Clinicians rated adult inpatients, adult day hospital patients, and adolescent inpatients at admission and discharge from psychiatric treatment. All samples were rated as significantly less dysfunctional at discharge. There were also significant differences in mean levels of dysfunction between the adult and adolescent samples at admission and discharge. These discrepancies were hypothesized to be associated with the GAF's unclear instructional format. Although this study concerned the GAF as described in the DSM-III-R, our findings are likely to be generalizable to DSM-IV, because no substantive changes have been made to the GAF.
