Audio computerized self-report interview use in prenatal clinics: audio computer-assisted self interview with touch screen to detect alcohol consumption in pregnant women: application of a new technology to an old problem.

Computer interviewing to obtain sensitive information is not a new concept. However, concerns about the acceptance of computers in disadvantaged populations with potentially low literacy led us to combine audio- and touch-screen technologies with an audio computerized self-report interview to obtain information about alcohol use. This study evaluated acceptance and ease of use by a disadvantaged population of pregnant women in the District of Columbia. Patients attending an initial visit at prenatal clinics answered questions anonymously about their consumption of alcoholic beverages and other personal information. The questionnaire was programmed on a laptop computer. The computer administered the recorded questions via earphones, as well as displayed them on the screen, and patients answered by touching the computer screen. Results were immediately available. A total of 507 women were interviewed, who were primarily African American, non-Hispanic, and never married. Nearly 24% did not complete a high school education, 43% were unemployed, and 30% received public assistance. Most of the women (59%) used computers occasionally (a few days a month) or never. Nearly all patients (96%) reported that the computer was not difficult to use, and approximately 90% liked answering the questions by computer. The study demonstrates that using computers to screen for alcohol use in disadvantaged pregnant populations is feasible and acceptable to the patients.

AUDIO AND VIDEO COMPUTER-ASSISTED SELF INTERVIEWING: Preliminary Tests of New Technologies for Data Collection.

Results are reported from a preliminary study testing a new technology for survey data collection: audio computer-assisted self interviewing. This technology has the theoretical potential of providing privacy (or anonymity) of response equivalent to that of paper self-administered questionnaires (SAQs). In addition, it could offer the advantages common to all computer-assisted methods such as the ability to implement complex questionnaire logic, consistency checking, etc.. In contrast to Video-CASI, Audio-CASI proffers these potential advantages without limiting data collection to the literate segment of the population. In this preliminary study, results obtained using RTI's Audio-CASI system were compared to those for paper SAQs and for Video-CASI. Survey questionnaires asking about drug use, sexual behavior, income, and demographic characteristics were administered to a small sample (N = 40) of subjects of average and below-average reading abilities using each method of data collection. While the small sample size renders many results suggestive rather than definitive, the study did demonstrate that both Audio- and Video-CASI systems work well even with subjects who do not have extensive familiarity with computers. Indeed, respondents preferred the Audio- and Video-CASI to paper SAQs. The computerized systems also eliminated errors in execution of "skip" instructions that occurred when subjects completed paper SAQs. In a number of instances, the computerized systems also appeared to encourage more complete reporting of sensitive behaviors such as use of illicit drugs. Among the two CASI systems, respondents rated Audio-CASI more favorably than Video-CASI in terms of interest, ease of use, and overall preference.
