However, the data were collected using the ACASI
system, which provides privacy and confidentiality and is designed to avoid much of the difficulty commonly experienced in securing full and frank responses on sensitive and intimate subjects when a respondent is one-on-one with an interviewer.
data collection was used to minimize underreporting of potentially embarrassing, stigmatized or illegal behaviors (Metzger et al.
This report presents the results of the first qualitative and quantitative evaluation of an ACASI
system in a large, household-based survey, using data collected in a national survey in poor households throughout Mexico.
Use of ACASI
for questionnaire delivery was important for maintaining confidentiality of data and inclusion of precoital screening questions limited exposure of sexually inexperienced students to more explicit questions.
However, as noted, the NLSY97 collected sensitive information using ACASI
(Audio Computer Assisted Self-interview) technology in order to minimize measurement error.
Face-to-face and ACASI
: The primary methods for data collection were a face-to-face interview and the ACASI
Effective approaches to user-interface design with ACASI

We guarded against this by using ACASI
, which has been shown to decrease the likelihood of socially desirable responses during collection of personally sensitive data (Des Jarlais et al.
, investigators asked open-ended questions about strategies to reduce HIV transmission among inmates.
Participants in this study were randomly assigned to face-to-face interviews or ACASI
has been found an effective and reliable method for obtaining confidential information such as sexual risk-taking behavior.
Newer methods to collect self-reports of sensitive behaviors have been developed including computer-assisted personal interviewing (CAPI), computer-assisted self-interviewing (CASI), audio computer assisted self-interviewing (ACASI
), telephone ACASI
and handheld computers.
