Interviews have been conducted biennially since 1992. The general practice, after wave 1, has been to include a check for $20 along with an advance letter sent to each sample member prior to their being contacted, by telephone or face-to-face, by an interviewer. The experiment consisted of changing the amount of the incentive check for randomly selected sample members, with the objective of examining the effect of incentive size in the response rate, on the amount of effort required to finalize the case, and the quality of the data obtained from respondents. In this paper, we examine the effects of the size of the incentive on the response rate on the immediate wave, and also briefly examine the effects on the number of calls. }, keywords = {Healthcare, Methodology}, url = {http://www.asasrms.org/Proceedings/y2002/Files/JSM2002-000340.pdf}, author = {Rogers, Willard} }
