The GESIS pretest database provides researchers access to findings of cognitive pretests conducted by the GESIS pretest lab. You can find, for example, the following information on a tested question:

• How do respondents understand the question or specific terms?
• Is the question understood in the way intended by the researcher?
• How easy or difficult is it to answer the question?

The database can either be searched using the list of topics on the left or by using the search function.
