QDDS II: a questionnaire development documentation system

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. The program should be suitable for paper&pencil, face-to-face and CATI instruments. A database for each questionnaire will contain information on formal aspects of each question, such as response categories and mode of answering (pick any that apply, ranking, magnitude estimation etc.). Furthermore formal criteria, such as type of question, character of replies, context and subject of the question can be saved.


The project was funded January 2006 - September 2007 by the German Research Foundation.
