This article examines respondent reactions to and performance on a self-administered component of a computerassisted personal interview survey on self-images, conducted in the Detroit area in 1992. Although respondents were encouraged to complete the computer-assisted self-interview items themselves, only 79 percent of those interviewed actually did so, while for 14 percent the interviewer completed the items and for the remaining 7 percent the interviewer read the questions while the respondent entered the responses. We find that the decision to self-complete the computer-assisted self-interview items is related to factors such as respondents' age, education and computer experience. This suggests that both capacity (literacy and vision) and motivation affect the choice of completion. We also find differences in substantive responses and data quality between self-completers and those who use interviewer assistance. These findings have implications for nonresponse error and data quality for self-administered components of interviews, particularly those using computer-administration.
Résumé. Utilisation d'Interviews Personnelles Assistées par Ordinateur (IPAO) dans l'enquête nationale américaine sur la santé. La "National Health Interview Survey" (NHIS) est une enquête suivie représentative de la population civile des Etats-Unis qui implique des interviews annuelles avec 48.000 foyers (120.000 personnes). Les instruments de collecte de données comprennent un questionnaire central sur la santé et la démographie et des annexes designées pour traiter des questions d'actualité sur la santé. Depuis plusieurs années, un travail de développement et de recherche a & e a c u t e ; t & e a c u t e ; mené avec un système d'interview personnelle assistée par ordinateur (IPAO) qui, partir de 1988, a & e a c u t e ; t & e a c u t e ; utilisé dans la NHIS pour collecter des données sur les attitudes et connaissances concernant le SIDA (syndrome d'immuno-déficience acquise). Actuellement, on compte faire la NHIS entièrement par IPAO en 1992. Une présentation des développements et des recherches dans ce domaine est faite et des utilisations concrètes de IPAO sont décrites. Les thèmes traités comprennent: les choix de matériel et de logiciels, la qualité des données, les délais de préparation des données, la capacité de déclencher rapidement une enquête, et les coûts.

The National Health Interview Survey (NHIS) is a continuous cross-sectional survey of the civilian population of the U.S., involving annual interviews with 48,000 households (120,000 persons). Data collection instruments include a core health and demographic questionnaire and one or more supplements designed to address current health issues. For several years, research and developmental work have been pursued via a computer-assisted personal interview (CAPI) system, which, since 1988, has been used with the NHIS to collect data on AIDS (acquired immune deficiency syndrome) knowledge and attitudes: there are plans to rely entirely on the CAPI mode by 1992. A summary is provided of the research and development work to date, and substantive uses of CAPI are described. Issues addressed include: hardware and software choices, data quality, timeliness of data release, quick-turnaround survey capability, and cost. National Health Interview
