There are several types of CAI systems commonly used in epidemiology:
Computer-Assisted Personal Interviewing (CAPI): Interviewers use a computer to guide the interview and record responses. Computer-Assisted Telephone Interviewing (CATI): Similar to CAPI but conducted over the phone, allowing for remote data collection. Computer-Assisted Web Interviewing (CAWI): Respondents complete the questionnaire online, providing flexibility and convenience.
