Background

Due to pretest results, a questionnaire is usually revised several times during construction. For several purposes, such as data analysis and data storage, as well as further questionnaire development in future studies, it is necessary to document those revisions in detail. This extensive documentation is also indispensable for teaching in survey research.
Nonetheless, this documentation is usually done only partially or not at all, due to a lack of useful documentation tools.

Based upon the ideas of Frauke Kreuter and Rainer Schnell, the aim of this project was the development of a program system that allows permanent electronic documentation of questionnaire development and the final state of the instrument.
