Research Report
The California Health Interview Survey (CHIS) has employed an addressed-based sampling (ABS) frame with a mail push-to-web interview followed by a telephone nonresponse follow-up as the primary data collection approach since 2019. However, the nature of the self-administered web survey results in more survey break-offs than the previous computer-assisted telephone interview (CATI).
