Study: Gay couples are vastly happier than heterosexual couples. So
How do they know that gender roles are the reason why? I'd still like to see the real data, though. Read times. There can be quite a few false positives when people think they should say - "my relationship makes me happy".
We used multinomial logistic regression to identify correlates with relationship structure, and linear and logistic regression to investigate associations between relationship structure and testing, condom use, and relationship satisfaction. Male caregivers actually reported more time spent as caregivers than their female counterparts.
Empirical evidence is sparse on this point, however. The British Journal of Psychiatry. Testing Behaviors Table 4 includes logistic regression of testing behaviors and linear regression of condom use and relationship satisfaction by relationship agreement, using monogamous participants as the reference group.
This latter finding in particular is reminiscent of results of earlier research, particularly Lee's study of older Canadian gay men and Adelman's study of a small sample of gay men and lesbians over age 60 in the San Francisco Bay Area.
