In ZIS (German: Zusammenstellung sozialwissenschaftlicher Items und Skalen) more than 260 empirically tested measurement instruments (as of spring 2020) by researchers in the social sciences and measurement instruments developed by GESIS staff are published in ZIS. For example, measurement of political attitudes and personality are documented. The instruments, their development, their quality criteria, and information on their theoretical background are documented. As a user, you can search for, and retrieve, the instruments online. As an author, you can publish your instruments in ZIS. All documented instruments are freely accessible and may be used for research purposes. ZIS is a cost-free GESIS offering.
Use the extensive search function to conduct a targeted search for specific topics or authors, or for instruments with a certain number of items.
