Yesterday the American Psychological Association passed a resolution supporting full marriage equality for same-sex couples by a unanimous vote of 157-0. Although the full text of the resolution is not yet available, the APA has supported same-sex marriage for several years, always citing peer-reviewed research to support their views. This quote from The Examiner is an excerpt from the proceedings of the 2010 annual convention (held last year during the California Prop 8 battle):
Research has shown that marriage provides substantial psychological and physical health benefits due to the moral, economic and social support extended to married couples. Conversely, recent empirical evidence has illustrated the harmful psychological effect of policies restricting marriage rights for same-sex couples. Additionally, children raised by same-sex couples have been shown to be on par with the children of opposite-sex couples in their psychological adjustment, cognitive abilities and social functioning.
APA has been a strong advocate for full equal rights for LGBT people for nearly 35 years, based on the social science research on sexual orientation. APA has supported legal benefits for same-sex couples since 1997 and civil marriage for same-sex couples since 2004. APA has adopted policy statements, lobbied Congress in opposition to the Defense of Marriage Act and the Federal Marriage Amendment, and filed amicus briefs supporting same-sex marriage in legal cases in Oregon, Washington, New Jersey, New York (three times), Maryland, Connecticut, Iowa, and California. In California, the APA brief was cited by the state Supreme Court when it ruled that same-sex marriage was legal in May 2008.
