English title: Setting Priorities: Spurious Differences in Response Rates
Author(s): Annelies G. Blom -
Type: Journal article
Response rates are a key quality indicator of a survey. Thus, their comparability across surveys and countries is pivotal. The first round of the European Social Survey contains a natural experiment in the estimation of response rates. While all countries implemented the same standardized contact protocol to record the outcome of each contact attempt, no instructions were given as to how to code a final case disposition from these individual contact attempts and each country chose its own strategy. We demonstrate that the coding strategy chosen has a substantial impact on the response rates reported. In particular, contact and cooperation rates derived by means of different coding strategies are incomparable across countries when intensive refusal conversion efforts are in place.
