An increasing number of social science surveys use split questionnaire designs to reduce questionnaire length, presenting only a subset of several questionnaire modules to each respondent while leaving out others. This approach results in large amounts of planned missing data that necessitates imputation. Research shows that imputation is most effective when each module covers various topics. Yet, ...

This paper outlines two studies on education bias in German probability-based surveys. Study 1 reviews data from 67 surveys across 19 survey programs conducted in Germany from 2000 to 2023. We found a consistent underrepresentation of individuals with a low level of formal education. We also found that the transition to self-administered modes due to rising survey costs may exacerbate this bias in ...

Research shows that concurrent and sequential self-administered mixed-mode designs both have advantages and disadvantages in terms of panel survey recruitment and maintenance. Since concurrent mixed-mode designs usually achieve higher initial response rates at lower bias than sequential mixed-mode designs, the former may be ideal for panel recruitment. However, concurrent designs produced high share ...

Das SCP ist eine Längsschnittstudie, die vielfältige Aspekte des gesellschaftlichen Zusammenhalts in Deutschland erfasst. Es basiert auf einer repräsentativen Bevölkerungsstichprobe aus deutschen Einwohnermelderegistern und wurde 2021 zum ersten Mal durchgeführt (n=17.027). Neben den zufällig ausgewählten Ankerpersonen richtet sich die jährliche Befragung auch an deren erwachsene Haushaltsmitglieder. ...
Social relationships are central to well-being because they fulfill social affiliation needs. To explain how social needs are regulated, theories describe daily-life processes among social desire, social contact, and affect. Still, these processes remain empirically underexplored because of their complexity. In this study, we estimated multivariate associations of social desire and affect with social ...

Der englische Originaltitel des Seminars lautet: “Who stays? Tracking ultra-long-time participants in the SOEP”. Die Präsentation findet auf Englisch statt.
Earnings are often top-coded (right-censored) in administrative registers. The censoring threshold in the case of Germany is the limit value for social security contributions, leading to a substantial fraction of censoring: For example, about 12%of male workers inWest Germany are affected, rising to above 30% for highly educated prime-aged workers. This missing right tail of the earnings distribution ...
