The documentation of the original ALLBUS survey instruments includes the German ISSP-modules administered together with ALLBUS since 1986 as well as additional survey materials such as showcards etc.
Since 2000 the ALLBUS-series uses CAPI as method of data collection. The documentation of CAPI-instruments comprises the complete question programm as well as all relevant routing information. Check routines and purely technical variables are not routinely documented.
English translations of ALLBUS questionnaires have been regularly made available since ALLBUS 1996. Apart from a translation of the ALLBUS-questions, the documentation includes the English language masterquestionnaires of the ISSP-modules administered with ALLBUS. Showcards and other interview materials are only available as part of the original language documentation.
