| Description | The Katz Adjustment Scales (KAS; Katz & Lyerly, 1963) are inventories designed to assess the adjustment and social behavior of pre-psychotic and ex-hospital psychiatric patients in the community. These scales utilize ratings from both the patient and a close relative to provide a comprehensive view of the patient’s functioning. The tool includes several forms, such as Form R1 (Relative’s Ratings of Patient Symptoms and Social Behavior) and Form S1 (Symptom Discomfort), designed to measure aspects like symptomatology, social behavior, free-time activities, and satisfaction with activities. The scales show high internal consistency and stable relationships with other measures in the set, although no factor analysis data is available. |
