CROSS-VALIDATION OF DIFFERENCES BETWEEN USERS AND NONUSERS OF SENIOR CENTERS

Discriminant analysis was used to compare users and non-users of senio r centers in two samples of older adults. The model accurately classif ied 70-80% of the two samples. This was the first study to cross-valid ate findings both within and between samples. Included in the model we re variables from four domains: predisposing, enabling, need, and link age to the older adult service system. Variables measuring linkage to the service system explained more variance than any of the other varia ble domains.
