[Audio Computer-Assisted Interview: a new technology in the assessment of sexually transmitted diseases, HIV, and drug use].

Reliable responses are crucial when applying questionnaires on sensitive and stigmatized behaviors. This challenge has motivated researchers to develop new data collection methods. We conducted a systematic literature review on the implementation, effectiveness, reliability, and validity studies of ACASI (Audio Computer-Assisted Interview) in the assessment of drug use and sexual behavior. We reviewed 24 papers, none of which published by Brazilian researchers, and only three of which describing research implemented outside the United States. The studies showed that the computerized method is able to reduce psychological barriers linked to the collection of sensitive health-related information, thereby increasing its reliability. According to the surveys, the ACASI format is a fast and valid assessment method for large samples. ACASI generates databanks that can be easily processed and analyzed.
