Conceptualization and Measurement of Health for Adults in the Health Insurance Study: Vol. I, Model of Health and Methodology
Jan 1, 1980
Seventh in a series on Health Insurance Study (HIS) measures, this volume describes the use and interpretation of power analysis as applied to physical and mental status measures fielded by the HIS. The report discusses the philosophy and formulae of power analysis, the actual power of the health status scales in the HIS setting, and the implications of these power levels for testing policy-relevant hypotheses. Results indicated that these scales are acceptably precise for HIS purposes. Knowledge of their experimental precision may help policymakers decide how much weight to give health status findings in deliberations about national health insurance. Power analysis also provides estimates of the extent of differences between insurance plans that can be expected to be detected.
