Model of Health and Methodology
First in a series reviewing published literature and documenting conceptualization and construction of health status measures used in the Health Insurance Study (HIS). The volume includes considerable detail on the methods used to select and enroll the HIS sample and collect health status questionnaire data. Multitrait (modified Likert) and Guttman scaling techniques assured that HIS batteries satisfied assumptions of each scaling method. Internal-consistency, test-retest, and reproducibility methods permitted evaluation of measurement reliability. Analyses of face and content validity were a first step in validation. Construct validation relied on theory and empirical evidence about relationships among measures. Study methods discussed here are not presented in other volumes.
