Amidst the challenges of declining response rates and escalating costs in survey research, the adoption of innovative new data collection designs such as planned missingness and split questionnaire designs is becoming increasingly prevalent. This dissertation addresses the imputation of social survey data from split questionnaire designs and the methodological decisions associated with implementing ...
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 ...
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 producea high share ...
The German Social Cohesion Panel (SCP) is a probability-based self-administered longitudinal study in a mixed-mode design (PAPI and CAWI) that is jointly carried out by the Research Institute Social Cohesion (RISC) and the German Socio-Economic Panel (SOEP). The aim of the study is to capture the diversity of social cohesion in Germany from multiple perspectives, particularly regarding the extent to ...
