English title: Is it worthwhile reducing the non-response rate by multiplied contact attempts? The example of ESS round 5 and 6 in Poland
Author(s): Pawel B. Sztabiński -
Type: Book chapter
In Chapter 8, Pawel Sztabinski – national co-ordinator in Poland of the ESS in all rounds – pursues the question of repeated contact attempts in the surveys. His analysis aims to determine whether or not repeated contacts help to include more diverse groups of respondents in the survey and whether or not this leads to a reduced risk of non-response bias. Two stages are applied: (i) comparison of answers given by harder-to-reach respondents with distributions for easy-to-reach ones and (ii) showing how the differences in those distributions translate into survey estimates. This allows determination of whether multiplying contact attempts is a productive effort and if so, how many times such contact attempts should be repeated. Sztabinski draws on the 2010 and 2012 European Social Survey data from Poland. His analyses disclose that although the responses to some questions were very different in subsamples identified by accessibility, this nevertheless did not translate into differences in survey estimates. They also suggest that repeated contact attempts do not lead to a significant change in the structure of the effective sample and have a very low effect on the degree of non-response bias.
