One way to organize the empirical conclusions related to marital satisfaction and aging is to categorize them according to “Attitude” and “Action” factors. The attitude of the marriage describes spouse’s opinions about the quality of the bond and the overall emotional climate of the relationship. Action characteristics, on the other hand, are the kinds of activities regularly engaged in by satisfied couples. This entry presents the traits of satisfied older couples, provides a brief discussion of gender differences, and concludes with implications based on the scientific findings.
