Assessment offunctional abilities is a key problem in providing and evaluating long-term
health care for the elderly. This study examines reliability issues involved in these
measurements performed by a multidisciplinary service team within a geriatric care
program. Rater agreement is found to be affected by measurement constraints in the
service delivery setting, work roles, and value differences among staff. Target areas for
improving standardization of data collection by service providers are indicated.
