Medical History Questionnaire Series

The codebooks in this volume describe the contents of six data files from the Health Insurance Experiment, a large social experiment conducted by The RAND Corporation from 1974 to 1982 in six sites across the United States. This volume documents files in the medical history questionnaire series, a series of survey instruments that gathered self-reported health status and health satisfaction data primarily from insured participants in the experiment. It contains the codebooks for the infant enrollment and exit Form A and Form B files, which consist of identifying variables for each participant and question variables from the various enrollment and exit medical history questionnaires. Form A measured health habits, perceptions, and attitudes; Form B measured specific health status.
