%X introduction: globally, population surveys on hiv/aids and other sensitive topics have been using audio computer-assisted self interview for many years. this interview technique, however, is still new and little is known about its application and impact in general population surveys in vietnam. one plausible hypothesis is that residents of vietnam interviewed using this technique may provide a higher response rate and be more willing to reveal their true behaviors than if interviewed with traditional methods. objective this study aims to compare audio computer-assisted self interview with traditional face-to-face personal interview and self-administered interview with regard to rates of refusal and affirmative responses to questions on sensitive topics related to hiv/aids. methods in june 2010, a randomized study was conducted in three cities (ha noi, da nan and can tho), using a sample of 4049 residents aged 15 to 49 years. respondents were randomly assigned to one of three interviewing methods: audio computer-assisted self interview, personal face-to-face interview, and self-administered paper interview. instead of providing answers directly to interviewer questions as with traditional methods, audio computer-assisted self-interview respondents read the questions displayed on a laptop screen, while listening to the questions through audio headphones, then entered responses using a laptop keyboard. a mysql database was used for data management and spss statistical package version 18 used for data analysis with bivariate and multivariate statistical techniques. rates of high risk behaviors and mean values of continuous variables were compared for the three data collection methods. results audio computer-assisted self interview showed advantages over comparison techniques, achieving lower refusal rates and reporting of higher prevalence of some sensitive and risk behaviors (perhaps indication of more truthful answers). premarital sex was reported by 20.4% in the audi
