Interval studies of pupils (panel studies)

Interval studies of the ZIJ Leipzig

In the following overview are seven interval studies from research on pupils from the former Central Institute for Youth Research Leipzig (Zentralinstituts für Jugendforschung - ZIJ) which are linked, as they related to each other substantively and methodologically. The studies are already available via the GESIS Central Archive. The codebooks, which were produced at the German Youth Institute, Regional Office Leipzig (Deutschen Jugendinstitut, Regionale Arbeitsstelle Leipzig), also contain, alongside substantive and methodological information, notes on publications and research reports, which were created in the GDR along with the data.
