CUMULATIVE ILLNESS RATING SCALE

Abstract: A Cumulative Illness Rating Scale, designed to meet the need for a brief, comprehensive and reliable instrument for assessing physical impairment, has been developed and tested. The scale format provides for 13 relatively independent areas grouped under body systems. Ratings are made on a 5-point “degree of severity” scale, ranging from “none” to “extremely severe.” Findings, in terms of reliability and validity, reflect statistical significance at the P < .01 level. As a rapid assessment technique which is objective and easily quantified, the scale is well suited to a variety of research uses.
