Components of self-rated health among adults: analysis of multiple data sources.
Four data sources were used to examine competing interpretations of self-rated health measures: whether they are best classified as summary indicators of both physical and psychological health status, or merely as surrogate measures of physical health. Multiple regression analysis revealed that, within each data source, measures of physical health and depression were each independently associated with general health status ratings after six sociodemographic indicators (sex, race, age, education, income, and residence) were held constant. These results were confirmed using both cross-sectional and longitudinal models, and using several different indicators of physical health. They suggest that researchers should be cautious in interpreting global health ratings, as they contain significant information regarding the psychological, as well as physical, health status of respondents.
