ABSTRACT
The Katz Adjustment Scales (Katz & Lyerly, 1963) were originally developed to help assess patients before their admission to a psychiatric hospital and after their return to the community. Although the most common use of these scales in the past was as a research instrument for assessing patients following their discharge from a psychiatric hospital, the scales have been used in a variety of ways. In recent years, one of the Katz Scales (originally called the Rl scale, now Part 1 of the KAS-R) has become a standard assessment instrument in the rehabilitation of patients with traumatic brain injury. This scale also shows promise as a general measure to plan and monitor treatment and to assess treatment outcome. This chapter summarizes the development of the Katz Adjustment Scales, reviews the reliability and validity data for the scales, and samples from the extensive research on the scales' usefulness in planning and monitoring treatment and in assessing treatment outcome.
