This paper describes a new interview data collection system that uses a lap
top personal computer equipped with a touch-sensitive video monitor. The to
uch-screen-based audio computer-assisted self-interviewing system, or touch
screen audio-CASI, enhances the ease of use of conventional audio CASI sys
tems while simultaneously providing the privacy of self-administered questi
onnaires. We describe touch screen audio-CASI design features and operation
al characteristics. In addition, we present data from a recent clinic-based
experiment indicating that the touch audio-CASI system is stable, robust,
and suitable for administering relatively long and complex questionnaires o
n sensitive topics, including drug use and sexual behaviors associated with
HIV and other sexually transmitted diseases. (C) 2001 Elsevier Science Ltd
