| Abstract: | The purpose of this study was to examine the abilityof the Health Utility Index-Mark III (HUI-Mark III) toprovide a summary measure of the physical, mental andsocial dimensions of health assessed in the 1994/5National Population Health Survey (NPHS). The sampleconsisted of 838 (402 male, 436 female) randomlyselected residents of Prince George, British Columbia.An exploratory factor analysis was conducted using themeasures of physical, psychological and social healthincluded in the NPHS. The HUI-Mark III scores werethen regressed on to the factors in an attempt todetermine the proportion of variance in factor scoresaccounted for by the HUI-Mark III. The results suggestthat the HUI-Mark III is primarily a measure ofphysical impairment that does not adequately representthe physical, mental and social dimensions of healthas measured in the NPHS. |
