One of the key ingredients of a happy and conflict-free long-term marriage is husband's pleasing nature and good health, says a new study.
University of Chicago researchers also found that such characteristics in wives play less of a role in limiting marital conflict, perhaps because of different expectations among women and men in durable relationships.
Study's lead author James Iveniuk, candidate in the Department of Sociology, said that wives report more conflict if their husband is in poor health but if the wife is in poor health, there doesn't seem to be any difference in terms of the quality of the marriage for the husband.
The study reports results from a national survey with data analyzed from 953 heterosexual couples who were married or cohabitating.
The study participants ranged in age from 63 to 90 years old and the average length of their relationships was 39 years.
The survey of older adults participating in the National Social Life Health and Aging Project, funded by the National Institute on Aging, compared the characteristics of the husbands to the characteristics of their wives and vice versa based on interviews with each person in which they were asked to describe themselves.
Iveniuk and co-authors found many gender differences, when they examined personality traits including openness to experience, conscientiousness, extraversion, agreeableness and anxiety.
They added a new measure called "positivity," an overarching characteristic described as a person's overall desire to be seen in a positive light.
Wives whose husbands show higher levels of positivity reported less conflict, however, the wives' positivity had no association with their husbands' reports of conflict, Iveniuk added.
The study was published in the Journal of Marriage and Family.
