==== Sample project ====

As an introduction to working with REDCap, a sample questionnaire has been created which contains all the important field types and functions:\\
[[https://redcap.zih.tu-dresden.de/redcap/surveys/?s=YR3DNYJRPFTC8X89|REDCap sample project live preview]]

This makes it easier to familiarise yourself with the system and create initial queries. A zip-file of the sample questionaire can be downloaded {{ :tools:redcap_questionaire_2024.zip |here}}. It only needs to be imported in yours REDCap project by clicking on the upload button in the Designer.

==== Catalog of already available tests ==== 

Some of the psychological tests commonly used have already been implemented in REDCap. A list of the implemented tests can be found here:\\
[[https://redcap.zih.tu-dresden.de/redcap/surveys/?s=D78RTCJE3A8C9W3Y|Catalog of psychological tests]]. 

When a test is selected a preview of the respective questionnaire is shown. The form linked at the end of the overview page can be used to request zip-folders of the desired questionnaires. The file then has to be uploaded in the REDCap project where it is supposed to be used later.

**Note:** Some fields are not supposed to be visible for the participants during data collection. These fields should additionally be marked with the Action-Tag //@HIDDEN-SURVEY//.
