Factors influencing the use of adult day care by individuals with Alzheimer's disease: a multivariate examination of the California Alzheimer's Disease Diagnostic and Treatment Center Program.

Longitudinal data from the California State Alzheimer's Disease Diagnostic and Treatment Center Program (ADDTC) are analyzed to determine what factors, including ADDTC staff recommendations for service use, influence utilization of adult day care services by individuals with Alzheimer's disease. The records of 737 clients are examined from 1988 to 1992 to determine predictors of client service utilization (including client predisposing, enabling, and need characteristics; caregiver characteristics; and community characteristics). Results of logistic regression analyses indicate that ADDTC staff recommendations and previous use of adult day care services are significantly related to use of adult day care services. Other client predisposing, enabling, and need characteristics; caregiver characteristics; and community characteristics were not significantly related to service use.
