Predictors of in-home and out-of-home service use by family caregivers of Alzheimer's disease patients.

Few studies have examined whether the use of different types of services is predicted by different characteristics of elderly care recipients and primary kin caregivers. Most research aggregates services into a single category, thereby assuming that different services have the same predictors. This investigation differs from the aggregation approach by comparing four groups of elderly care recipients: in-home service of users, out-of-home service users, users of both in- and out-of-home services, and those who do not use services. Data come from personal interviews with 171 family caregivers of mild to moderate dementia patients who reside in the community. Using the modified Andersen framework and multiple group discriminant analysis, results show that care recipients who do not use services and those using only in-home services have inadequate informal supports, more emotionally strained caregivers, and more functionally impaired care recipients compared with users of out-of-home or both in- and out-of-home services.
