Mixed-mode surveys are popular as they can save costs and maintain (or improve) response rates relative to single-mode surveys. Nevertheless, it is not yet clear how design decisions like survey mode or questionnaire length impact measurement quality. In this study, we compare measurement quality in an experiment of three distinct survey designs implemented in the German sample of the European Values Study: a single-mode face-to-face design, a mixed-mode mail/web design, and a shorter (matrix) questionnaire in the mixed-mode design. We compare measurement quality in different ways, including differences in distributions across several data quality indicators as well as equivalence testing over 140 items in 25 attitudinal scales. We find similar data quality across the survey designs, although the mixed-mode survey shows more item nonresponse compared to the single-mode survey. Using equivalence testing we find that most scales achieve metric equivalence and, to a lesser extent, scalar equivalence across the designs. [ABSTRACT FROM AUTHOR]

During the COVID-19 pandemic, many survey programs switched to self-administered modes of data collection, often offering respondents both web-based and paper-based questionnaires. However, there is little guidance as to when to offer which mode, especially when the aim is to recruit participants for a panel survey. This study examines the effectiveness of different mode-sequence designs by analyzing an experiment implemented in the recruitment wave of the German panel study "Family Research and Demographic Analysis." We randomly assigned 108,256 individuals aged 18–49 years to one of three mode-sequence-design conditions: concurrent, web-first including a paper-based questionnaire with the second reminder (web-first-2), and web-first including a paper-based questionnaire with the third reminder (web-first-3). A fourth, simulated group did not receive a paper-based questionnaire (web-only). We analyzed how different mode-sequence designs affected outcome rates, sample composition, response distributions, data quality, share of paper-based questionnaires, postage costs, number of postal mailings in the recruitment wave, and participation in the first regular wave. Our results show no differences in response distributions and small differences in sample composition across the four mode-sequence designs. As the web-first-2 and simulated web-only designs yielded comparatively good response and recruitment rates at reasonable costs, we recommend their use when surveying adults between 18 and 49 years old.

This study examines the consequences of the pandemic on subjective well-being. First, we investigate to what extent regional and temporal differences in COVID-19 restrictions can explain individuals' life satisfaction in Germany. Second, we examine to what extent "subjective" evaluations of the pandemic are related to life satisfaction. Third, we examine whether these relationships vary with gender, parenthood, and partnership status, or whether relationships changed regarding specific sub-populations (i.e., mothers, fathers, childless women/ men). Merging representative survey data from the German Family Demography Panel Study (FReDA) and contextual data on COVID-19 restrictions (i.e., the stringency index), we analyze a sample of 32,258 individuals living in Germany in their regional settings on the NUTS-3 level during the "second lockdown" in spring 2021. Furthermore, we use the FReDA field period between April and June 2021 to assess temporal variations in COVID-19 restrictions and their association with life satisfaction. To answer our research questions, we compare aggregated means and use variance decomposition and multivariate regression models. Our results show strong regional and temporal differences in COVID-19 restrictions, but neither temporal nor regional differences in "subjective" perceived pandemic burden or in life satisfaction at the aggregated level. At the individual level, we find substantive negative associations between perceived pandemic burden and life satisfaction, which are particularly strong among mothers. Our study shows that individuals' negative perceptions of the pandemic are an important correlate to life satisfaction, whereas regional differences or temporal changes in COVID-19 restrictions appear to be irrelevant for the period under investigation.

In Germany, the population registers with addresses of individuals can be used for addressbased sampling. However, unlike countries with a centralized register, municipalities in Germany administer their registers themselves. This not only makes sampling for a nationwide survey more costly and cumbersome but may also result in gaps in the gross sample, as selected municipalities may refuse to allow their registers to be used for sampling purposes. If substitute municipalities are not available, other sampling methods are required. The present study tested the feasibility of using the address database from Deutsche Post Direkt (ADB-DPD) as an alternative frame for address-based sampling in Germany. We simultaneously conducted two almost identical surveys in the German city of Mannheim with gross samples of equal size (N = 3,000). One sample was drawn from the city's population register, the other from the commercial ADB-DPD. Our findings suggest that the ADB-DPD performs well both in terms of survey response and up-to-dateness. Due to relatively low costs and the fast provision of addresses, the ADB-DPD could be particularly attractive for survey projects with limited budgets and tight schedules. However, these benefits come at considerable cost. First, the use of the ADB-DPD is limited to self-administered surveys. More importantly, in the net sample of the DPD survey, women and young persons were considerably underrepresented. This indicates coverage issues about which DPD provided no further information. Based on our analyses, we offer practical insights into the feasibility of using the ADB-DPD for sampling purposes and suggest avenues for future research. [ABSTRACT FROM AUTHOR]

Dyadic surveys aim to interview pairs of respondents, such as partners in a relationship. In dyadic surveys, it is often necessary to obtain the anchors' consent to contact their partners and invite them to a survey. If the survey is operated in self-administered modes, no interviewer is present to improve the consent rate, for example, by providing convincing arguments and additional information. To overcome the challenges posed by self-administered modes for dyadic surveys and to improve consent rates, it is important to identify aspects that positively influence the likelihood of anchors giving consent to contact their partners. Ideally, these aspects are in the hands of the researchers, such as the survey design and aspects of the questionnaire. Thus, in this study, we analyzed the relationship between anchors' survey experience and their willingness to consent to surveying their partners in self-administered modes. Based on data from the German Family Demography Panel Study (FReDA), we found that the anchors' perceptions of the questionnaire as "interesting" or "too personal" were related to consent rates. These relationships were consistent across different survey modes and devices. Effects of other aspects of the questionnaire, such as "important for science" and "diverse" varied between modes and devices. We concluded with practical recommendations for survey research and an outlook for future research. [ABSTRACT FROM AUTHOR]

Implementing innovations in surveys often results in uncertainty concerning how different design decisions will affect key performance indicators such as response rates, nonresponse bias, or survey costs. Thus, responsive survey designs have been developed to better cope with such situations. In the present study, we propose a responsive survey design that relies on experimentation in the earlier phases of the survey to decide between different design choices of which—prior to data collection—their impact on performance indicators is uncertain. We applied this design to the European Values Study 2017/2018 in Germany that advanced its general social survey‐type design away from the traditional face‐to‐face mode to self‐administered modes. These design changes resulted in uncertainty as to how different incentive strategies and mode choice sequences would affect response rates, nonresponse bias, and survey costs. We illustrate the application and operation of the proposed responsive survey design, as well as an efficiency issue that accompanies it. We also compare the performance of the responsive survey design to a traditional survey design that would have kept all design characteristics static during the field period. [ABSTRACT FROM AUTHOR]

This article discusses the current challenges of conducting a General Social Survey (GSS) in face-to-face mode and evaluates the alternative of fielding these surveys in self-administered mixed-mode (web, mail) instead. Based on data from Germany, it first illustrates the stark decline of participation in face-to-face surveys since 2002 and reports a strong increase in the cost of conducting these surveys over the same period. It then discusses the possibility of implementing GSS-type surveys in a self-administered design and reports results from a mode experiment implemented in the German part of the European Values Study (EVS) 2017/18. The results of the experiment indicate that self-administered mixed-mode surveys are a viable alternative for cross-sectional general population surveys in Germany; they shorten the fieldwork period and lead to higher response rates, while being more cost-efficient than face-to-face surveys. Despite the finding that the sample composition deviates from the general population in both modes, the face-to-face mode represents the population slightly better. [ABSTRACT FROM AUTHOR]

The European Values Study (EVS) was first conducted in 1981 and then repeated in 1990, 1999, 2008, and 2017, with the aim of providing researchers with data to investigate whether European individual and social values are changing and to what degree. The EVS is traditionally carried out as a probability-based face-to-face survey that takes around 1 hour to complete. In recent years, large-scale population surveys such as the EVS have been challenged by decreasing response rates and increasing survey costs. In the light of these challenges, six countries that participated in the last wave of the EVS tested the application of self-administered mixed-modes (Denmark, Finland, Germany, Iceland, the Netherlands, and Switzerland). With the present data brief, we will introduce researchers to the latest wave of the EVS, the implemented mode experiments, and the EVS data releases. In our view, it is pivotal for data use in substantive research to make the reasoning behind design changes and country-specific implementations transparent as well as to highlight new research opportunities.

How can we explain the recent decline of trust in representative institutions of the EU in many of its Member States? This article presents evidence supporting the congruence hypothesis, according to which citizens have been extrapolating their increasing distrust in national institutions to the EU institutions. We also find that these contagion effects are produced by citizens' evaluations of national governments. Furthermore, we show that these spillover effects from the national to the EU level tend to be stronger in situations of economic recession and political crisis. The only counterbalance to this contagion comes from citizens' positive evaluation of EU performance. We test these general arguments based on a twofold panel analysis of the Spanish case, a country that has suffered a remarkable deterioration of political trust in a context of profound economic and political crisis, by analysing data from a micro-level panel study and 28 pooled surveys from the Eurobarometer between 1999 and 2015.

This study tests the links between political and economic performance and satisfaction with democracy (SWD) in Spain. Contrary to the dominant theoretical paradigm that explains the aggregate evolution of and the individual-level differences in SWD mainly by means of economic factors, the article presents evidence that evaluations of the political process are equally relevant to account for both changes in individuals’ SWD over time and the evolution of SWD at the national level. Unlike most existing literature, this study supports its argument by combining analyses of a micro-level panel dataset (CIUPANEL) and of a pooled aggregate-level panel dataset based on the Spanish samples in the Eurobarometer and the Latinobarómetro between 1986 and 2014.
