What is ZIS?

  • ZIS stands for the Collection of Items and Scales for the Social Sciences (German: ZIS - Zusammenstellung sozialwissenschaftlicher Items und Skalen). ZIS contains more than 250 instruments, e.g. items for measuring political attitudes or personality.

  • Each instrument documentation includes the instrument itself and information about the instrument’s theoretical background, development, and quality criteria.

  • The ZIS instruments are sorted by topics. Please click on a topic to view the corresponding instruments. The selected topic will be marked orange.

  • All measurement instruments are free for the purpose of non-commercial research (more license information at the GESIS-Homepage).

  • You yourself can contribute by publishing your instrument in ZIS (Upload-Portal).
