Survey return rates using a covering letter signed by a graduate student or faculty member

This study assessed differences in response rate when the author of a survey was identified as a graduate student or a faculty member. A survey on research ethics was mailed to 500 nurse faculty members with half of the covering letters signed as a graduate student and half signed as a faculty member. There were 388 (78%) out of a possible 495 surveys returned. The response rate was 78% for graduate student and 77% for faculty identifications, not significant by chi-square test.
