A Probability-Based Mixed-Mode Access Panel
for the Social Sciences

GESIS Panel Longitudinal Core Studies

Within each data collection wave, about five to seven minutes of interviewing time are reserved for thematic modules of the GESIS Panel Longitudinal Core Study.

One aim of the GESIS Longitudinal Core Study is to measure longitudinally frequently demanded characteristics of enduring interest to the social sciences. Another aim is to assess indicators and proxy variables of data quality with a view to facilitating the estimation of potential survey errors and biases. In 2020, the GESIS Panel revised the core studies and the layout of the surveys. Below you will find the old and the new versions of the questionnaires as PDFs.

Each year, GESIS Panel Longitudinal Core Study modules are fielded according to the following schedule:
