In order to conduct successful survey research, suitable survey instruments, such as items, scales, indices, for measuring social science attributes and psychological characteristics are indispensable. With the established Open Access Service ZIS, GESIS offers scientists these validated survey instruments for non-commercial research purposes. As of now, researchers can access additional survey instruments via the ZIS search: Thanks to a cooperation with the Research Data Center (FDZ) for Education at the DIPF | Leibniz Institute for Research and Information in Education, researchers can now access a broader repertoire of survey instruments for educational research.
