Logistic regression analysis was used to compare users and non-users of sen
ior centers. Variables assessing linkage to the service system were more si
gnificant predictors of senior center utilization than predisposing, enabli
ng, or need variables. More specifically, users of senior centers were olde
r and more likely to live in rural areas. They also had more social contact
s, better mental health, and fewer ADL problems. Senior center users were a
lso more aware of specific service agencies, more likely to consult formal
resources in making service decisions, and more likely to have used other s
ervices.
