THE VALIDITY OF THE KATZ-ADJUSTMENT-SCALE AMONG PEOPLE WITH TRAUMATICBRAIN INJURY

Deficits in self-and social awareness can impair adjustment following traumatic brain injury (TBT) and draw into question the accuracy of se lf-report measures of adjustment. This study evaluates the validity of Katz Adjustment Scale (KAS) factor components identified by R. J. Fab iano and D. A. Goran (1992). The KAS is an observer rating scale often used to assess the social adjustment of people with traumatic brain i njury. The responses of 105 individuals with TBI to the Symptom Checkl ist 90-Revised (SCL-90-R; L. R. Derogatis, 1983), a self-report measur e of distress, were correlated with observer ratings on the KAS. Resul ts support the use of observer ratings and self-report to assess adjus tment and social behavior following TBI. Each contributes valuable inf ormation that can guide treatment and enhance adaptive functioning.
