How are the survey instruments created?
Some items in HINTS are borrowed from existing national-level surveys (e.g., CDC’s Behavioral Risk Factor Surveillance System); some come from smaller surveys related to health, and some are created by members of the HINTS program at the National Cancer Institute. In all cases, items are carefully tested before the survey is fielded to ensure that they are psychometrically sound. The on-line codebook documents the source of every item in HINTS (see the Survey Notes field).
