The department Survey Design & Methodology (SDM) is both nationally and internationally recognized for its expertise in survey methodology, gained over many years by conducting own research as well as consulting on and implementing renowned survey projects. The goal of our research is to broaden the understanding of the survey process. Our expertise finds its way into our methodological consultation services and into the operational services that we offer, such as sampling, pretesting, field monitoring or survey data collection within the GESIS Panel.
The Cross-Cultural Surveys team focuses on the methodology of cross-cultural and cross-national studies. Its research and services aim at testing and ensuring intercultural equivalence and, thus, comparability of data. The team focuses on the translation and adaptation of measurement instruments.
The ESS team is part of the Core Scientific Team of the European Social Survey (ESS ERIC) and jointly with their partners they assure the quality of the collected data, specifically by coordinating the questionnaire translation and monitoring the field activities. To guarantee the best possible accuracy and comparability of the collected data, the national ESS teams are individually advised, supported, and evaluated.
The Survey Design & Evaluation team supports users in the development and evaluation of questionnaires. Cognitive pretests (face-to-face, web probing, and eye-tracking) are conducted to test the quality of survey questions. The results of those pretests are published in our pretesting data base. In research and consultation services, the team addresses topics such as question wording and response formats, the harmonization of variables between surveys, and especially the measurement of socio-structural variables.
The GESIS Panel offers social scientists the opportunity to collect survey data within a probability-based mixed-mode access panel free of charge. Academics of a diverse set of disciplines can submit their proposals. The resulting data is made available to the scientific community for secondary use.
The Scale Development & Documentation team develops and documents survey instruments in the social sciences and underpins these services with their own research in this area. The collection of items and scales for the social sciences (CIS) is the key service of this team. More than 200 survey instruments have been published so far.
The Survey Operations team focuses on the optimization of all field-related decisions, tasks, and processes and in that considers specifically longitudinal surveys. The team’s services to the community focus in particular on survey project planning and field monitoring. Moreover, the team is participating in several PIAAC follow-up projects, thereby collecting, analyzing, and documenting basic competencies among the adult population. The resulting data is made available to the scientific community via the FDZ PIAAC (PIAAC research data center).
The Survey Statistics team offers extensive advice regarding sample design and the analysis of survey data. Our services also include the drawing of samples, especially telephone samples using both landline and mobile phones, as well as the development and calculation of survey weights.
