This paper provides a timely evaluation of whether the main COVID-19 lockdown policies – remote work, short-time work and closure schools childcare have an immediate effect on German population in terms changes satisfaction with family life. Relying individual level panel data collected before during lockdown, we examine (1) how individuals changed over period, (2) lockdown-driven labour market situation (i.e. working remotely being sent work) affected satisfactions. We apply...
A rich and diverse literature exists on the effects that human interviewers can have different aspects of survey data collection process. This research synthesis uses Total Survey Error (TSE) framework to highlight important historical developments advances in study interviewer a variety process outcomes, including sample frame coverage, contact recruitment potential respondents, measurement, processing. Included scope is has focused explaining variability among these types variable errors...
Many policy analyses on COVID-19 have been focusing what kind of policies are implemented to contain the spread COVID-19. What seems equally important explore social and political consequences confinement policies. Does public support strict policies? social, political, psychological The question how legitimate a is among at core democratic theory. Its relevance also stems from expected behavior: more someone supports policy, likely follow even if not strictly enforced. In this paper, we...
Nonprobability online panels are commonly used in the social sciences as a fast and inexpensive way of collecting data contrast to more expensive probability-based panels. Given their ubiquitous use science research, great deal research is being undertaken assess properties nonprobability relative probability ones. Much this focuses on selection bias, however, there considerably less assessing comparability (or equivalence) measurements collected from respondents This article contributes...
This article looks into the processes and outcomes of setting up maintaining a probability-based longitudinal online survey, which is recruited face-to-face representative both offline population aged 16–75 in Germany. German Internet Panel studies political economic attitudes reform preferences through bimonthly interviews individuals. The results presented here demonstrate that carefully designed implemented panel can produce high-quality data at lower marginal costs than existing panels...
Inferential statistics teach us that we need a random probability sample to infer from the general population. In online survey research, however, volunteer access panels, in which respondents self-select themselves into sample, dominate landscape. Such panels are attractive due their low costs. Nevertheless, recent years have seen increasing numbers of debates about quality, particular errors representativeness and measurement, such panels. this article, describe four probability-based...
During the COVID-19 pandemic, one way to reduce further transmissions of SARS-CoV-2 is widespread use contact tracing apps. Such apps keep track proximity contacts and warn persons who tested positive for an infection.
The past decade has seen a rise in the use of online panels for conducting survey research. However, popularity panels, largely driven by relatively low implementation costs and high rates Internet penetration, been met with criticisms regarding their ability to accurately represent intended target populations. This criticism stems from fact that (1) non-Internet (or offline) households, despite small size, constitute highly selective group unaccounted (2) preeminent nonprobability-based...
Abstract Survey data collection costs have risen to a point where many survey researchers and polling companies are abandoning large, expensive probability-based samples in favor of less nonprobability samples. The empirical literature suggests this strategy may be suboptimal for multiple reasons, among them that probability tend outperform on accuracy when assessed against population benchmarks. However, often preferred due convenience costs. Instead forgoing sampling entirely, we propose...
In survey research, a consensus has grown regarding the effectiveness of incentives encouraging participation across different modes and target populations. Most this research been based on surveys from United States, whereas few studies have provided evidence that these results can be generalized to other contexts. This paper is first present comprehensive information concerning effects response rates nonresponse bias large-scale in Germany. The context could viewed as critical test for...
Recent years have seen a growing number of studies investigating the accuracy nonprobability online panels; however, response quality in panels has not yet received much attention. To fill this gap, we investigate comprehensive study seven and three probability-based with identical fieldwork periods questionnaires Germany. Three indicators typically associated survey satisficing are assessed: straight-lining grid questions, item nonresponse, midpoint selection visual design experiments. Our...
This paper evaluates the inequalities in employment trajectories during first COVID-19 pandemic lockdown Germany. We assess individual-level panel data collected weekly between 20 March and 25 June (N=2,297), which allows us to examine risks of short-time work, furlough, job loss, as well changes working on-site from home. Using sequence analysis, we detect typical patterns analyse how these vary socio-demographic groups. Finally, relate types income, subjective security (compared values...
Research has shown that the non-Internet population is hesitant to respond online survey requests. However, also subgroups in Internet with low digital affinity may hesitate surveys. This latter issue not yet received much attention by scholars despite its potentially detrimental effects on external validity of data. In this article, we explore extent which a person’s contributes nonresponse bias German Panel, probability-based panel general population. With multidimensional classification...
Abstract Carefully designed probability-based sample surveys can be prohibitively expensive to conduct. As such, many survey organizations have shifted away from using probability samples in favor of less expensive, but possibly accurate, nonprobability web samples. However, their lower costs and abundant availability make them a potentially useful supplement traditional We examine this notion by proposing method supplementing small with Bayesian inference. consider two semi-conjugate...
The outbreak of the COVID-19 pandemic has a massive impact on society. To curb spread SARS-CoV-2 virus, unprecedented containment measures are being taken by governments around world. These and fear disease itself likely affecting economy, social inequality, mental physical health, even people’s perception good democratic governance. Equally is speed at which these changes take place lack statistical evidence that accompanies them. Within days first in Germany, German Internet Panel (GIP)...
Abstract The rapid increase in smartphone surveys and technological developments open novel opportunities for collecting survey answers. One of these is the use open-ended questions with requests oral instead written answers, which may facilitate answer process result more in-depth unfiltered information. Whereas it now possible to collect answers on smartphones, we still lack studies impact this format characteristics respondents' In study, compare linguistic content versus political...
In face-to-face surveys interviewers play a crucial role in making contact with and gaining cooperation from sample units. While some analyses investigate the influence of on nonresponse, they are typically restricted to single-country studies. However, interviewer training, contacting strategies as well survey climates may differ across countries. Combining call-record data European Social Survey (ESS) detailed questionnaire attitudes doorstep behavior we find systematic country differences...
Questionnaire design is routinely guided by classic experiments on question form, wording, and context conducted decades ago. This article explores whether two order effects (one due to the norm of evenhandedness other subtraction or perceptual contrast) appear in surveys probability samples United States 11 countries (Canada, Denmark, Germany, Iceland, Japan, Netherlands, Norway, Portugal, Sweden, Taiwan, Kingdom; N = 25,640). Advancing theory effects, we propose necessary conditions for...

This response behavior is detectable web surveys using paradata. study investigates whether to what extent switch away from survey search for online JavaScript OnBlur functions. Respondents were randomly assigned device types (PC or smartphone) formats (open closed) answered a self-report question. The...
Once recruited, probability-based online panels have proven to enable high-quality and high-frequency data collection. In ever faster-paced societies and, recently, in times of pandemic lockdowns, such survey infrastructures are invaluable social research. absence email sampling frames, one way recruiting a panel is via postal mail. However, few studies examined how best approach then transition sample members from the initial mail contact registration. To fill this gap, we implemented...
