Change in Body Weight of Older Adults before and during the COVID-19 Pandemic: Longitudinal Results from the Berlin Aging Study II

ObjectivesChange in body weight during the COVID-19 pandemic as an unintended side effect of lockdown measures has been predominantly reported for younger and middle-aged adults. However, information on older adults for which weight loss is known to result in adverse outcomes, is scarce. In this study we describe the body weight change in older adults before, during, and after the COVID-19 lockdown ...

The Performance of Multiple Imputation in Social Surveys with Missing Data from Planned Missingness and Item Nonresponse

Designs using planned missingness, such as the split questionnaire design, are becoming more and more important in social survey research. To ensure an acceptable questionnaire length, these approaches typically entail large amounts of planned missing data, which can be imputed after data collection. However, social surveys typically also include other types of missingness such as item nonresponse ...

Restrictions to Civil Liberties in a Pandemic and Satisfaction with Democracy

In times of crises, democracies face the challenge of balancing effective interventions with civil liberties. This study examines German states’ responses during the early stages of the COVID-19 pandemic, focusing on the trade-off between civil liberties and public health. Using state-level variation in mobility restrictions, we employ a difference-in-differences design to show that stay-at-home orders ...

Codevelopment of Life Goals and the Big Five Personality Traits Across Adulthood and Old Age

Since the new millennium, research in the field of personality development has focused on the stability and change of basic personality traits. Motivational aspects of personality and their longitudinal association with basic traits have received comparably little attention. In this preregistered study, we applied bivariate latent growth curve modeling to investigate the codevelopment of nine life ...

Validating an Index of Selection Bias for Proportions in Non-probability Samples

Fast online surveys without sampling frames are becoming increasingly important in survey research. Their recruitment methods result in non-probability samples. As the mechanism of data generation is always unknown in such samples, the problem of non-ignorability arises making vgeneralisation of calculated statistics to the population of interest highly questionable. Sensitivity analyses provide a ...

Measuring Expenditure with a Mobile App: Do Probability-Based and Nonprobability Panels Differ?

In this case study, we examine a novel aspect of data collected in a typical probability and a typical nonprobability panel: mobile app data. The data were collected in Great Britain in 2018, using the Innovation Panel of the UK Household Longitudinal Study and the Lightspeed online access panel. Respondents in each panel were invited to participate in a month-long study, reporting all their daily ...

DECIPHE – Demographic Change and the Intergenerational Persistence in Homeownership in Europe

DECIPHE is the first project to comprehensively study whether and how profound demographic changes in Europe impact the intergenerational persistence of homeownership, considering variations across countries, regions, and birth cohorts. It adopts a life course framework on housing tenure, in which individuals’ homeownership is shaped by their household members’ preferences and resources and...

DECIPHE – Demographic Change and the Intergenerational Persistence in Homeownership in Europe

DECIPHE ist das erste Projekt, das umfassend untersucht, ob und wie tiefgreifend sich demografische Veränderungen in Europa auf die intergenerationale Persistenz von Wohneigentum auswirken. Dabei werden Unterschiede zwischen Ländern, Regionen und Geburtskohorten berücksichtigt. Das Projekt nimmt  eine Lebensverlaufsperspektive auf Wohneigentum ein, bei der die Präferenzen und Ressourcen der...

Study on the Effectiveness of COVID-Aid on Firms

The study investigates the impact of COVID-related State aid measures (COVID-aid) on firms’ performance in selected EU countries, distinguishing among different categories of (pre-crisis) firm size, economic sector, and type of financial instrument received. The current analysis covers three countries with available National State Aid Registries, namely Italy, Poland, and Spain, which enable precise ...

Cookbooks, Guidance, and Best Practice: Working Group Charter (NFDI Section-metadata) ; (Meta)data, Terminologies, Provenance

Forschende brauchen auf ihre spezifischen Bedürfnisse zugeschnittene Hilfestellungen bei der Ermittlung und Anwendung von Standards und Werkzeugen für (Meta)Daten, Terminologien und Provenienz. Jedes NFDI-Konsortium identifiziert, sammelt und entwickelt Ansätze, die für Forschungsaktivitäten außerhalb der einzelnen Domänen relevant sein könnten. Die Arbeitsgruppe "Cookbooks, Guidance, and Best Practices" ...

Individual Differences in Short-term Social Dynamics: Theoretical Perspective and Empirical Development of the Social Dynamics Scale

People have a need to form and maintain fulfilling social contact, yet they differ with respect to with whom they satisfy the need and how quickly this need is deprived or overly satiated. These social dynamics across relationships and across time are theoretically delineated in the current article. Furthermore, we developed a questionnaire to measure individual differences in three aspects of such ...

Video-interviewing as part of a targeted multi-mode design in household panel surveys (CALVI)

To ensure continued survey participation and data quality, the survey landscape must adapt to the changing social reality, especially with regard to mobility and digitalization. This requires survey researchers to move from one-size-fits-all solutions to a data collection strategy that takes into account people's communication habits, abilities and preferences. For several decades, computer...

Video-interviewing as part of a targeted multi-mode design in household panel surveys (CALVI)

Um die kontinuierliche Teilnahme an und Datenqualität von Umfragen sicherzustellen, muss sich die Umfragelandschaft an die sich verändernde gesellschaftliche Realität anpassen, insbesondere im Hinblick auf Mobilität und Digitalisierung. Dies erfordert, dass Umfrageforschende von Einheitslösungen zu einer Datenerhebungsstrategie übergehen, die die Kommunikationsgewohnheiten, Fähigkeiten und...

Surveying Panel Participants’ Network Members: Integration of Egocentric Data Collection and Respondent-Driven Sampling

Individuals are embedded in social contexts: although many large-scale, cross-thematic social science surveys already attempt to do justice to this fact, so far research has only been partially successful. The aim of this study is to supplement and improve the existing data collection strategies - survey designs for multiple actors (MA) and questionnaire modules for egocentric networks (ECN) -...

Surveying Panel Participants’ Network Members: Integration of Egocentric Data Collection and Respondent-Driven Sampling

Individuen sind in soziale Kontexte eingebettet, diesem Umstand versuchen bereits viele großangelegte, themenübergreifende sozialwissenschaftliche Befragungen gerecht zu werden – dies gelingt aber bislang nur bedingt. Das Vorhaben dieser Studie besteht darin, die bestehenden Datenerfassungsstrategien – Umfragedesigns für multiple Akteure (MA) und Fragebogenmodule für egozentrierte Netzwerke (ECN)...

Bridging Distance: Transnational and Local Family Ties in Refugees’ Social Support Networks

This study examines the familial ties in the social support network of refugees in Germany. Itinvestigates whether distance to family plays a role in the provision of emotional and informationalsupport and how this relationship is moderated by social network services (SNS). Usingdata from the IAB-BAMF-SOEP Survey of Refugees (N¼5237), the paper provides evidence for afamily-centred network. Increasing ...

Response Quality in Nonprobability and Probability-based Online Panels

Recent years have seen a growing number of studies investigating the accuracy of nonprobability online panels; however, response quality in nonprobability online panels has not yet received much attention. To fill this gap, we investigate response quality in a comprehensive study of seven nonprobability online panels and three probability-based online panels with identical fieldwork periods and questionnaires ...
