Rehabilitation status: a measure of medicosocial dysfunction.

The Edinburgh Rehabilitation Status Scale (ERSS) measures four dimensions in which changes may occur in the course of a disabling illness or during rehabilitation: independence; activity; social integration; and effects of symptoms on lifestyle. It provides a profile of measures, the scores of which can be summated to indicate the overall level of performance of individuals or groups. Studies of its inter-observer reliability and of its application in various disability groups indicate that the ERSS reliably defines the characteristics of individual patients and of groups. The scale can be used conveniently by professional staff working independently or by a multiprofessional rehabilitation team to assess status and changes in patients. It can also be used for measurement of the effectiveness of services and for purposes of research, teaching, and administration.
