U.S. sociologists say depressed singles receive greater psychological benefits from getting married than do those who are not depressed.

While many studies have shown marriage helps boost well-being, most have looked at a general, average population and did not examine whether some people were helped more by marriage than others.

Our findings question the common assumption that marriage is always a good choice for all individuals, said Adrianne Frech, co-author of the study and a doctoral student in sociology at Ohio State University.

Frech conducted the study with Kristi Williams, assistant professor of sociology. Williams said the study is the first to compare how depressed and non-depressed people benefit from marriage.

We thought depressed people would be less likely to benefit from marriage because the depression of one spouse can put a strain on the marriage and undermine marital quality, said Frech. "We actually found the opposite of what we expected.

Frech presented the study during the weekend in Montreal at the annual meeting of the American Sociological Association.
