Rogers Susan M., Gribble James N., Turner Charles F., Miller Heather G.- Computerized self-interviewing and the measurement of sensitive behaviors Surveys that rely on respondents to provide information on sensitive, stigmatized, or illicit behaviors may be subject to reporting bias. Audio computer-assisted self-interview (audio-CASI) technology has been developed by researchers at the Research Triangle Institute, USA to overcome the limitations of traditional paper and pencil self-administered questionnaires (SAQs) and in-person interviewer-administered questionnaires (IAQs). The development of audio-CASI technology has fundamentally altered the interview context for measuring sexual and other sensitive behaviors by providing privacy without requiring literacy. This paper reviews the scientific development of audio-CASI and describes the results of methodological experiments comparing audio-CASI with other survey interview modes. In 1995, RTI's audio-CASI technology was field tested in two major U.S. national surveys: The National Survey of Adolescent Males (NSAM) and the National Survey of Family Growth (NSFG). These surveys found substantially higher levels of reporting of drug use, same gender sexual contact and induced abortion with audio-CASI than IAQs or SAQs.
