The main conclusions were that preparedness for adoption, mental health of parents, and the strength of the parents’ relationship with each other all impacted the development of the children; the parents’ sexual orientation did not.
The mantra that children need a mother and a father in the home to do well is the main one I hear now from the anti-gay marriage groups. This study disproves that—at least as far as children in their early years.
The study used internalizing and externalizing scores to measure children’s outcomes. A child with high externalizing scores is a child who acts out and exhibits behavior problems. A child with high internalizing scores keeps everything inside and is prone to depression, phobias, etc. I wasn’t familiar with the way of evaluating children’s mental health but found it very persuasive. It’s probably a good way of evaluating anyone’s mental health.
At any rate, an interesting, important study. Perhaps it will relieve the minds of people sincerely concerned about how the legality of same-sex marriage will affect the well-being of children.
