Objective: To test the theory of planned behavior (TPB) and other variables to discriminate among women who have made various decisions about hormone replacement therapy (HRT). Method: An anonymous survey was completed by a diverse sample of 641 women employed at a community college. Results: Survey response rate was 64.3%. Results from a discriminant analysis showed that HRT use was most strongly associated with perceived behavioral control and reliance on one's physician as a source of HRT information. Conclusions: The TPB is a useful framework for explaining HRT decisions in a period of uncertainty about risks and benefits of the therapy.
