The purpose of this study was to determine whether there are differences in donor constraints from former student-athletes at multiple NCAA institutions. The Former Student Athlete Donor Constraint Scale (FSADCS) was distributed to 5330 athletic alumni non-donors at four institutions, each representing a different NCAA classification. There were 231 usable responses creating a 4.3% response rate. MANOVA and correlation tests were utilized to investigate whether significant relationships exist for the following five questions: 1) Which donor constraints are greatest at each NCAA classification? 2) Is there an effect on donor constraint by participation in a specific sport? 3) Which donor constraints are most prevalent to male and female former student-athletes? 4) Which donor constraints are most prevalent with former student-athletes who reside in a different state? 5) Is there a relationship between donor constraints and household income? Significant differences in donor constraint responses were discovered when comparing NCAA classification as well as sport. These results contribute to the need for further research on former student-athlete donor constraints, and will also assist athletic development officers with their efforts to solicit additional revenue through donations from former student-athletes.
