This study investigates researcher variability in computational reproduction, an activity for which it is least expected. Eighty-five independent teams attempted numerical replication of results from original policy preferences and immigration. Reproduction were randomly grouped into a ‘transparent group’ receiving code or ‘opaque only method description no code. The transparent group mostly verified (95.7% same sign p -value cutoff), while the opaque had less success (89.3%). Second-decimal...
Abstract This article discusses the current challenges of conducting a General Social Survey (GSS) in face-to-face mode and evaluates alternative fielding these surveys self-administered mixed-mode (web, mail) instead. Based on data from Germany, it first illustrates stark decline participation since 2002 reports strong increase cost over same period. It then possibility implementing GSS-type design results experiment implemented German part European Values Study (EVS) 2017/18. The indicate...
How can we explain the recent decline of trust in representative institutions EU many its Member States? This article presents evidence supporting congruence hypothesis, according to which citizens have been extrapolating their increasing distrust national institutions. We also find that these contagion effects are produced by citizens' evaluations governments. Furthermore, show spillover from level tend be stronger situations economic recession and political crisis. The only counterbalance...
Abstract The European Values Study (EVS) was first conducted in 1981 and then repeated 1990, 1999, 2008, 2017, with the aim of providing researchers data to investigate whether individual social values are changing what degree. EVS is traditionally carried out as a probability-based face-to-face survey that takes around 1 hour complete. In recent years, large-scale population surveys such have been challenged by decreasing response rates increasing costs. light these challenges, six...

Abstract 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 when offer which mode, especially aim recruit participants for a panel survey. This study examines effectiveness different mode-sequence designs by analyzing an experiment implemented in recruitment wave German “Family Research Demographic Analysis.” We randomly...
Abstract This data brief introduces the German Family Demography Panel Study (FReDA; https://www.freda-panel.de/), a longitudinal, multi-actor database for family research. Major substantive fields addressed in questionnaire include fertility-related attitudes and behaviours, reproductive health, work-family conflict, couples’ division of labour, gender roles, intimate relationships, separation divorce, parenting intergenerational relations, well-being. FReDA is based on two initially...
The worldwide spread of the COVID-19 pandemic has disrupted fieldwork surveys. data collection efforts via face-to-face mode have been affected especially, including ongoing surveys that were in field during outbreak and planned scheduled for later 2020. We provide an account how impacted two family studies Germany: “The German Family Panel” (pairfam) “Generations Gender Survey” (GGS) both which will be part “Family Research Demographic Analysis” (FReDA) infrastructure. Based on pairfam, we...
Consensual-pluralistic institutional features of representative democracies have traditionally been associated with satisfaction democracy (SWD). However, more recent studies report contradictory results on the effects some these determinants SWD. This article confirms puzzling findings by showing that electoral proportionality increases SWD while other pluralistic factors such as government fractionalization produce opposite effect. We illustrate this duality counteracting expanding number...
We test the importance of responsiveness, performance and corruption to explain evolution political trust in Spain between 1997 2019. To this end, study analyses two longitudinal datasets, namely, a repeated cross-sectional dataset from Spanish samples Eurobarometer an individual-level panel survey conducted during period economic recovery 2015. The finds that perceptions about responsiveness matter greatly shaping lesser extent performance. Although Great Recession is likely responsible for...
This study tests the links between political and economic performance satisfaction with democracy (SWD) in Spain. Contrary to dominant theoretical paradigm that explains aggregate evolution of individual-level differences SWD mainly by means factors, article presents evidence evaluations process are equally relevant account for both changes individuals' over time at national level. Unlike most existing literature, this supports its argument combining analyses a micro-level panel dataset...
Abstract Implementing innovations in surveys often results uncertainty concerning how different design decisions will affect key performance indicators such as response rates, nonresponse bias, or survey costs. Thus, responsive designs have been developed to better cope with situations. In the present study, we propose a that relies on experimentation earlier phases of decide between choices which—prior data collection—their impact is uncertain. We applied this European Values Study...
Abstract This study examines the consequences of pandemic on subjective well-being. First, we investigate to what extent regional and temporal differences in COVID-19 restrictions can explain individuals’ life satisfaction Germany. Second, examine “subjective” evaluations are related satisfaction. Third, whether these relationships vary with gender, parenthood, partnership status, or changed regarding specific sub-populations (i.e., mothers, fathers, childless women/ men). Merging...
Dyadic surveys aim to interview pairs of respondents, such as partners in a relationship. In dyadic surveys, it is often necessary obtain the anchors’ consent contact their and invite them survey. If survey operated self-administered modes, no interviewer present improve rate, for example, by providing convincing arguments additional information. To overcome challenges posed modes rates, important identify aspects that positively influence likelihood anchors giving partners. Ideally, these...

In an era of mass migration, social scientists, populist parties and movements raise concerns over the future immigration-destination societies. What impacts does this have on policy solidarity? Comparative cross-national research, relying mostly secondary data, has findings in different directions. There is a threat selective model reporting lack replicability. The heterogeneity countries obscures attempts to clearly define data-generating models. P-hacking HARKing lurk among standard...
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 quality in an experiment of three distinct designs implemented the German sample European Values Study: a face-to-face design, mixed-mode mail/web shorter (matrix) design. We different ways, including differences...
Self-administered mixed-mode surveys are increasingly used as an alternative to face-to-face for collecting data from the general population. However, little is known about how decisions regarding incentive scheme and mode-choice design jointly affect key outcomes such response rates, net sample composition, survey costs. To study this, we drew a probability of residential population city Mannheim, Germany ( N = 2,980) randomly assigned target persons one four schemes (€0, €1, or €2 prepaid...
This study provides a synopsis of the current fieldwork monitoring practices large-scale surveys in Germany. Based on results standardized questionnaire, summarizes indicators used and measures carried out by 17 social sciences Our descriptive reveal that common set exist which studied rely. However, it also uncovers need for additional design-specific indicators. Finally, underlines importance close cooperation between survey representatives agencies to optimize processes German context....
