As the country awaits two important Supreme Court decisions involving state laws on ,
a small but consistent body of research suggests that laws that ban gay
marriage — or approve it — can affect the mental health of gay, lesbian
and bisexual Americans. When several states passed laws to prohibit
same-sex marriage, for example, the mental health of gay residents
seemed to suffer, while stress-related disorders dropped in at least one
state after gay marriage was legalized.
Here's the research trail:
Beginning
around 2004, several states banned gay marriage. Just before that
series of bans, the National Institutes of Health happened to conduct a
massive of 43,093 Americans. The questions elicited detailed
information about respondents' mental health. (To validate what people
reported about themselves, psychiatrists also interviewed samples of the
people in the survey, and their medical diagnoses closely matched the
findings of the survey.)
Soon after the wave of state bans on
gay marriage, in 2004 and 2005, the NIMH conducted a second round of
interviews, managing to reach 34,653 of the original respondents.
(That's a high rate compared with most polls and surveys.)
