Real or virtual? Response behavior in video-enhanced self-administered computer interviews. Field Methods

This article compares response behavior in video-enhanced self-administered questionnaires with three standard methods: paper-and-pencil, face-to-face, and audio-enhanced self-administered questionnaires. Although its scope is limited, and only small mode differences were observed, preliminary results suggest that video-enhanced interviews may produce more valid responses in that they are less contaminated by social desirability. Knowledge of video elements integrated in self-administered questionnaires has so far been limited. This study attempts to build a tentative theoretical framework for the interpretation of the mode differences established in the course of this research
