A meta-analysis was conducted of the health/subjective well-being relationship, based upon studies of United States adults published prior to 1980. Dependent variables were zero-order and first-order correlations. A total of 231 zero-order effect size estimates were extracted from 104 different sources, while a total of 189 first-order effect sizes were extracted from thirty-three different sources. The majority of effect sizes were derived from samples where the midpoint of the age range was sixty-five and over. The 95 percent confidence interval estimates, generated using Tukey's jackknife procedure, were .29 to .35 and .29 to .38 for the zero-order and first-order correlations, respectively. Using weighted regression procedures, univariate analyses indicated that all but one study and sample characteristics were significant (p less than .05) predictors of zero-order and first-order correlations, though none of the predictors adequately specified variation in effect sizes. The mean value of the first-order correlations varied with the type of control variable, ranging from .42 (age) to .27 (SES composite). Health and subjective well-being were found to be positively and significantly related. Limitations of the meta-analysis were noted and suggestions were made for strengthening research on this topic.
Meta-analytic techniques were used to synthesize findings on the social activity/subjective well-being relation. We chose zero-order and first order associations as our dependent variables and several different measure, sample, and study quality characteristics as our independent variables. We found that social activity is positively and significantly related to subjective well-being. Contrary to activity theory, informal activities and activities with friends were not related to subjective well-being consistently more strongly than were formal activities and activities with neighbors. In addition, the remaining measure, sample, and study quality characteristics were not adequate predictors of variation in activity/subjective well-being associations.
Meta-analytic techniques were used to synthesize findings on black-white differences in subjective well-being among noninstitutionalized adults. The dependent variable was zero-order estimates of the race/subjective well-being relation. Predictors were a composite of quality of study ratings, age midrange, and year of publication. We found that race is related to subjective well-being, with whites reporting slightly higher levels of subjective well-being than blacks. The composite of study quality was positively, and age midrange was inversely, related to race/subjective well-being associations. Year of publication was not an efficient predictor. These effect sizes indicate that black-white differences in subjective well-being decrease with age.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
