Psychogeriatric dependency rating scales (PGDRS): a method of assessment for use by nurses.
I M Wilkinson, J Graham-White

Abstract

Validity and reliability studies of a method of assessment of the elderly mentally ill by nurses are presented. The method has the advantages of being brief, meaningful and structured into three areas which provide useful distinctions for nursing: Orientation, Behaviour, and Physical Capacity. Applications of the scales are discussed.
