Marital status is associated with psychological well-being, with the married faring better than the formerly and never-married. However, this conclusion derives from research focusing more on negative than positive well-being. We examine the association between marital status and negative well-being, measured as depressive symptoms, and positive well-being, measured as autonomy, environmental mastery, personal growth, positive relations with others, self-acceptance, and purpose in life. Using Wave 2 of Midlife in the United States (2004–2006; n = 1,711), we find that the continuously married fare better on the negative dimension than do the formerly married. The results for some measures of positive well-being also reveal an advantage for the continuously married, compared with the formerly and the never-married. However, results for other positive measures indicate that the unmarried, and the remarried, fare better—not worse—than the continuously married. Further, some results suggest greater benefits for remarried or never-married women than men.
