ABSTRACT: Objective
Health scientists strive for a smooth recruitment of physicians for research projects like surveys. Teaching physicians are an easy to approach population that is already affiliated with a university by teaching students in their practice. How do response rates compare between a convenient online survey among teaching physicians and an elaborate postal survey in a random sample of unknown physicians? Data from the TMI-GP study on the use of memory tests in general practice were used.Results
Physicians in the random sample responded to the postal survey more often than teaching physicians to the online survey (59.5% vs. 18.9%; odds ratio 7.06; 95% confidence interval 4.81-10.37; p < 0.001). Although it is unclear whether the sample, the survey mode (online vs. postal) or both account for this effect, it is noteworthy that even in such a convenience sample of known/committed physicians, an adequate response rate could not be reached without a tailored and elaborated survey technique. Responders in the two samples were comparable regarding a content-related item (use of memory tests; Χ2 (df = 1) = 3.07; p = 0.080).
