An Analysis of Quasi-refusals in Telephone Survey
This paper analyzes nonresponse due to refusals in a telephone survey, and examines the effectiveness of attempts to persuade those who directly or indirectly refused to participate in the survey. This paper also compare the differences between those who agreed to participate in the survey from the beginning and those who initially refused, but were later persuaded to participate. Results indicate that there are no significant differences between them in demographic characteristics, nor significant differences in attitudes toward social, political, and economic issues. In addition, the efficacy of attempts to persuade those who initially refuse is unremarkable. The results of logistic regression analysis of refusal conversion show: (1) The contribution of experienced interviewers in refusal conversion is much greater; (2) Interview completion is less related to call attempts, but it's related to a longer contact; (3) Urbanization is an add-on factor for refusal conversion.
