FReDA regularly offers researchers the opportunity to contribute their own modules to the sample questionnaire. Most recently, in spring 2025, we asked scientists to submit proposals for open modules, which will then be included in the autumn survey of the sixth FReDA wave (W6B) in 2026. The submission deadline for this latest call ended on 26 May 2025.
The submitted proposals are currently being reviewed in terms of form and content. As soon as the final decision has been made as to which proposals can be included in the FReDA survey, we will inform you here.
A total of three minutes of survey time is available for the open modules in the questionnaire, which may consist of several submissions from different applicants. In past decisions, several different, shorter proposals from various scientific disciplines were always taken into account.
If you missed this year's call: no problem, the call for open modules will be repeated regularly. The next call for open modules will take place in spring 2025. We will inform you in good time on our website about the next call and the corresponding submission deadlines.
The open modules are an integral part of FReDA's question programme and are advertised regularly. However, as the FReDA questionnaire is the same as the GGS questionnaire every three years and no additions or deviations are possible for reasons of compatibility, no open modules can be integrated into the survey every third year. In 2021 and 2022, we therefore gave the scientific community the opportunity to submit their own proposals for modules or individual questions. In 2023, however, there was no call for reasons of compatibility with the GGS. In 2024, it was again possible to submit your own questions or modules. The next call will open in spring 2025.
We received numerous submissions for the autumn survey of the fifth FReDA wave (W5B) in 2025. In a multi-stage process, the FReDA committees selected the items to be included in the W5B wave in autumn 2025.
Gradational gender identity: measuring variations in self-rated femininity and masculinity Submitted by Prof. Dr Pia S. Schober (Eberhard Karls University of Tübingen)
Individual differences and longitudinal relationship predictors of family-friends interdependence Submitted by Prof. Dr Cornelia Wrzus (Ruprecht-Karls-University Heidelberg) and Dr Michael D. Krämer (University of Zurich)
Intergenerational transmission of parenting styles and their economic and social implications within families in Germany Submitted by Prof. Dr Daniel Schunk, Dr Katharina Hartinger, Erik Sarrazin, Maria Krempl and David Blum (Johannes Gutenberg University Mainz)
The modules are now being incorporated into the FReDA questionnaire and will be part of the sample in fall 2025.
We also called for proposals for modules or individual questions for the fall survey of the third FReDA wave (W3B) in 2023.
The following modules or questions were integrated and asked in the fall survey of the third FReDA wave (W3B):
If submitted proposals could not be considered in this survey wave, this is by no means due to the quality of the submitted modules, but to the limited survey time, which requires a selection.
In spring 2021, we issued the first call for open modules and gave researchers the opportunity to submit their own questions in the FReDA context. The submission deadline ended on June 30, 2021 - and the response to the call was very good: a total of 27 proposals were submitted. As we unfortunately only have around three minutes of survey time available for the W2B wave for the submissions, we had to make a selection from the proposals, all of which were very exciting.
The following modules will be integrated and asked in the fall module of the second FReDA wave (W2B) in 2022:
The newly added questions can then be linked and analysed together with all other information from the existing question catalogue.
New data: FReDA publishes the complete data set of the second survey wave. We summarize the most important information and figures for you.

How are the data collected in FReDA? You can find detailed information on the study’s samples, contents and survey modes here.
Twice a year, FReDA surveys people who live in Germany and were between 18 and 49 years old at the time of the first survey. The data form the basis for several different samples.
Every three years, FReDA is part of the Generations and Gender Survey (GGS). This makes international comparative analyses possible.
FReDA continues the surveys of the pairfam study so that these cohorts can also continue to be analysed.
The DFG funding of pairfam has ended as planned. But don't worry if you would like to continue your research with this dataset - the pairfam sample is now part of FReDA and will be continued in this way.
FReDA also asks the partners of all anchor persons to participate in the study. This makes dyadic analyses possible.
Data from Europe, Asia and Latin America: The Generations and Gender Survey (GGS) provides researchers with a very broad, up-to-date database from around 20 countries and territories. FReDA collected the data for Germany.
