Lois Collins at Deseret News reports on the new studies by Prof. Regnerus at Prof. Marks:

The oft-cited assertion that there are "no differences" in outcomes between children of same-sex parent households and those of intact biological families may not be accurate, according to a new study published today in the journal Social Science Research.

Adult children of parents who have been in same-sex relationships are different than children raised in intact biological families on a number of social, emotional and relationship measures, according to research from the University of Texas at Austin.

Among other things, they reported lower income levels, poorer mental and physical health and more troubled current romantic relationships. The study found 25 differences across 40 measures.

The research does not address why the differences exist. It doesn't predict if changing attitudes that are more accepting of same-sex relationships will mean that children growing up today with same-sex parents will one day fare better in similar analysis. It doesn't address stigma or whether the difference is not the sexual preference of the parents but rather how stable the home life was, lead investigator Mark Regnerus, associate professor of sociology at University of Texas Austin's Population Research Center, told the Deseret News.

"Nor does the study tell us that same-sex parents are necessarily bad parents," he said in a written statement. "Rather, family forms that are associated with instability or non-biological parents tend to pose risks for children as they age into adulthood."

His study does challenge long-held assertions that there are no outcome differences between children raised in intact biological families and those with same-sex parents.

The editorial board of Deseret has separately published a statement -- "In our opinion: Family structure counts".

The Washington Times reports on two new studies we are going to be hearing much more about in the coming days and weeks.

The first is by Prof. Mark Regnerus:

Two studies released Sunday may act like brakes on popular social-science assertions that gay parents are the same as — or maybe better than — married, mother-father parents.

“The empirical claim that no notable differences exist must go,” Mark Regnerus, a sociology professor at the University of Texas at Austin, said in his study in Social Science Research.

Using a new, “gold standard” data set of nearly 3,000 randomly selected American young adults, Mr. Regnerus looked at their lives on 40 measures of social, emotional and relationship outcomes.

He found that, when compared with adults raised in married, mother-father families, adults raised by lesbian mothers had negative outcomes in 24 of 40 categories, while adults raised by gay fathers had negative outcomes in 19 categories.

Findings such as these do not support claims that there are “no differences” between gay parenting and heterosexual, married parents, said Mr. Regnerus, who helped develop the New Family Structures Study at the university.

And a second study by Prof. Loren Marks:

The second study, also in Social Science Research, takes a critical look at the basis of an oft-cited American Psychological Association (APA) report on gay parenting.

The APA brief says, “Not a single study has found children of lesbian or gay parents to be disadvantaged in any significant respect relative to children of heterosexual parents,” said Loren Marks, associate professor at the School of Human Ecology at Louisiana State University.

However, after looking at the 59 studies that undergird this assertion, “the jury is still out,” Mr. Marks said. “The lack of high-quality data leaves the most significant questions [about gay parenting] unaddressed and unanswered.”

Problems with the APA-cited studies were their tiny size; dependence on wealthy, white, well-educated lesbian mothers; and a failure to examine common outcomes for children, such as their education, employment and risks for poverty, criminality, early childbearing, substance abuse and suicide. Instead, the APA studies often looked at children’s gender-role behaviors, emotional functioning and sexual identity.
