The Disability Rating Form: A brief schedule for rating disability associated with severe mental illness.

Abstract

The psychometric properties o f the Disability Rating Form, a new instrument for rating disability associated with severe mental illness, were examined. Therapists participating in a large-scale evaluation o f community-based crisis intervention services twice rated consumers with regard to their disability in five areas o f functioning using the Disability Rating Form. Analyses o f ratings on the five-item instrument revealed excellent item characteristics, stability o f item ratings over a 2-to 4-month interval, and consistency am ong items. Disability ratings were modestly associated with duration o f disability and w eakly associated with DSM-III-R diagnosis. Potential applications and limitations o f the instrument are discussed.

Additionally, validity of the measures is often established by comparing functioning scores with level of service utilized.…”
