Collegiate sport in the United States not only provides educational opportunities to student athletes, but also offers excellent entertainment options to stakeholders of universities and their community. For the long-term sustainability of college athletic programs, financial support from individual donors is very important. Our purpose in this study was to identify and compare motives of low- and high-contribution donors to athletic programs. A sample of college sport donors (N = 484) completed the Scale of Athletic Donor Motivation, and the data were categorized into low- and high-contribution groups. The results of multigroup structural equation modeling indicated that tangible benefit was a salient predictor of giving intention among the low-contribution group, whereas socialization was significant for the high-contribution group. Theoretical and practical implications are discussed.
