Abstract
Objective: The present study examined the association between marital satisfaction and all-cause mortality in a large, representative sample of American adults. Gender was evaluated as a potential moderator of this association.

Method: Ratings of marital satisfaction from married adults < 90 years of age (N = 19,246) were extracted from the 1978 – 2010 waves of the General Social Survey and linked to mortality data from the National Death Index. Discrete-time survival analysis was used to evaluate the association between marital satisfaction and mortality.

Results: After statistically adjusting for demographic variables, the odds of dying for married individuals who described their marriage as very happy or pretty happy were significantly lower than the odds of dying for married individuals who described their marriage as not too happy. The association between marital satisfaction and mortality was not moderated by gender.

Conclusions: The significant prospective association between marital satisfaction and mortality suggests that reducing marital dissatisfaction may increase longevity. Further longitudinal research is warranted to (a) replicate the current findings, and (b) evaluate whether increasing marital satisfaction through clinical intervention increases longevity
