A new study examining the correlation between religion and marital happiness found that women who are part of a highly religious, traditional couple are most likely to report being happy in marriage, as well as sexually satisfied in their relationship.

In addition, a woman in a highly religious couple was most likely to report that she and her spouse share responsibility for important household decisions, rather than one spouse making all the family’s decisions.

The study of families in 11 countries, conducted by the Institute for Family Studies, found that “highly religious couples in heterosexual relationships” enjoy happier marriages and more sexual satisfaction than less religious, mixed, or secular couples.
