The survey instruments are made available to you in the form of SUF and field versions. The field versions consist of the originally deployed PAPI questionnaires as well as the programming templates for CATI and CAPI as well as for CAWI and CASI interviews. The SUF versions entail additional information, such as the variable names and labels found in the Scientific Use Files as well as the corresponding scheme options. We recommend the SUF version, when working with the data. The ZIP archive contains all of the documents listed below.
In our Downloadcenter you can also view other survey instruments that don't yet have a published Scientific Use File. In order to access the instruments, logging in to the webstie is required. If you are not registered as a NEPS data user and therefore don't have the necessary login credentials, simply contact the Research Data Center.
