A new milestone has been reached with the inclusion of the latest item: The GESIS pretest database now comprises 3,000 items that have been cognitively tested at GESIS and are freely accessible.
The GESIS pretest database documents detailed information about the questions tested (e.g. how respondents understood them, whether they had difficulty answering them, etc.) together with recommendations for revising the questions derived from this information. So if you are developing a questionnaire and are looking for questions that have already been tested, we recommend that you take a look at the GESIS pretest database - build on our foundation.
