Abstract:
This study examined whether survey response rate differed based on the color of the paper the survey was printed on (blue vs green) and presence of a monetary incentive. A 4-page survey on eating disorders was mailed to Division 1A and 1AA college head athletic trainers (N=223) with half of the surveys on blue paper and half on green paper. Half of the athletic trainers (n = 111) received a $1.00 monetary incentive, and half (n = 112) received no monetary incentive. A total of 166 (71%) athletic trainers returned completed surveys. Response rates did not differ based on survey color but did differ based on presence of a monetary incentive. Athletic trainers who received a monetary incentive were significantly more likely than those who did not to return completed surveys (86% vs 63%, respectively).
