Standardization and validation of the Multidimensional Observation Scale for Elderly Subjects (MOSES)

Objective, reliable and valid means of assessing the cognitive and psychosocial functionings of elderly persons are in demand for several reasons. Clinical needs for initial assessment, placement, and treatment monitoring are supplemented by the need for research tools for program evaluation and clinical trials. The set of behavior rating scales called the Multidimensional Observation Scale for Elderly Subjects (MOSES) was developed with these needs in mind. This paper describes the development of the MOSES scale and its rationale and norming on 2,391 residents of hospitals and residential settings. Internal consistency reliabilities in the .8 range and interrater reliabilities from .58 to .97 are reported. Validity correlations with the Zung Depression, Robertson Short Mental Status, Kingston Dementia, and the Physical and Mental Impairment-of-function Evaluation (PAMIE) scales were all satisfactory. The applications and advantages of the use of MOSES are discussed.
