In conducting a survey study, the researcher may never have personal contact with the subjects. To recruit such subjects, one must rely on the use of attention-getting techniques, persuasively written material, and strategies for following up on individuals who do not respond to the initial written or e-mail communication. Because of the serious problems of low response rates in survey studies, using strategies to raise the response rate is critical. In some cases, small amounts of money ($1 to $5 dollars) are enclosed with the letter. This may produce a feeling of obligation on the part of the potential participant. Survey research return rate varies from 5% through about 50% for most studies. Interestingly, the accuracy of responses in survey research is slightly better with a lower return!
