Across survey organizations around the world, there is increasing pressure to augment survey data with administrative data. In many settings, obtaining informed consent from respondents is required before administrative data can be linked. A key question is whether respondents understand the linkage consent request and if consent is correlated with respondent understanding. In the present study, we investigate these issues in separate telephone and Web surveys, where respondents were presented with follow-up knowledge questions to assess their understanding of the linkage consent request. Overall, we find that understanding of the linkage request is relatively high among respondents who consent to …

Previous research has shown that people often engage in other activities while responding to surveys and that respondents’ multitasking generally has no effect on indicators of data quality (e.g., item non-response, non-differentiation). One of the limitations of these studies is that they have mostly used self-reported measures of respondents’ multitasking. We build on prior research by combining self-reported measures of multitasking with interviewers’ observations of respondents’ distractions recorded after each interview. The dataset comes from a statewide dual-frame random digit dial telephone survey of adults in a Midwestern state (n = 1,006) who were queried on topics related to awareness …

Response rates can be calculated by various means, allowing the researchers the usage of different disposition codes, which in turn can result in vastly different response rates for the same survey. One of the most comprehensive reporting conventions is the ‘Standard Definitions’ by the American Association of Public Opinion Research (AAPOR), which describes specific definitions of disposition codes and various outcome rates in great detail, allowing for only a marginal variance of results. In this inquiry, we aim to document the reporting of response rates and other survey characteristics in recent publications of scientific journals. Our analyses are based on …

With the decrease of landline phones in the last decade, telephone survey methodologists face a new challenge to overcome coverage bias. In this study we investigate coverage error for telephone surveys in Europe over time and compare two situations: classical surveys that rely on landline only with surveys that also include mobile phones. We analyzed Eurobarometer data, which are collected by means of face-to-face interviews and contain information on ownership of landline and mobile phones. We show that for the period 2000-2009, time has a significant effect on both mobile phone penetration and coverage bias. In addition, the countries’ development …
