A revised version of the Rapid Disability Rating Scale (RDRS‐2) is presented. Item definitions have been sharpened and directions expanded to indicate that ratings are based upon the patient's performance in regard to behavior, and that prostheses normally used by the patient should be included in the assessment. Three items have been added to increase the breadth of the scale. Response items have been changed from three‐point to four‐point ratings in order to increase group discrimination and make the scale more sensitive to changes in treatment. The new appraisals of reliability, factor structure, and validity are reported, along with the potential uses of the scale.
