Mixed Mode - Handling method-differences between paper and web questionnaires (PDF).
In this article, the authors show that in spite of identical design of a web questionnaire and a paper questionnaire (in principle the web questionnaire was printed), test subjects give significantly different answers depending on which version they fill out. Further, they give a few practical pieces of advice to people intending to do mixed mode and/or web surveying.
