Self-objectification and Well-being: The Impact of Self-objectification on Women’s Overall Sense of Self-worth and Life Satisfaction

A continuous assessment and a categorical diagnosis of the presence (i.e., flourishing) and the absence (i.e., languishing) of mental health were proposed and applied to the Midlife in the United States study data, a nationally representative sample of adults between the ages of 25 and 74 years (N = 3,032). Confirmatory factor analyses supported the hypothesis that measures of mental health (i.e., emotional, psychological, and social well-being) and mental illness (i.e., major depressive episode, generalized anxiety, panic disorder, and alcohol dependence) constitute separate correlated unipolar dimensions. The categorical diagnosis yielded an estimate of 18.0% flourishing and, when cross-tabulated with the mental disorders, an estimate of 16.6% with complete mental health. Completely mentally healthy adults reported the fewest health limitations of activities of daily living, the fewest missed days of work, the fewest half-day work cutbacks, and the healthiest psychosocial functioning (low helplessness, clear life goals, high resilience, and high intimacy).

Analytical solutions for point and variance estimators of the mediated effect, the ratio of the mediated to the direct effect, and the proportion of the total effect that is mediated were studied with statistical simulations. We compared several approximate solutions based on the multivariate delta method and second order Taylor series expansions to the empirical standard deviation of each estimator and theoretical standard error when available. The simulations consisted of 500 replications of three normally distributed variables for eight sample sizes (N = 10, 25, 50, 100, 500, 1000, and 5000) and 64 parameter value combinations. The different solutions for the standard error of the indirect effect were very similar for sample sizes of at least 50, except when the independent variable was dichotomized. A sample size of at least 500 was needed for accurate point and variance estimates of the proportion mediated. The point and variance estimates of the ratio of the mediated to nonmediated effect did not stabilize until the sample size was 2,000 for the all continuous variable case. Implications for the estimation of mediated effects in experimental and nonexperimental studies are discussed.
