The Christian Broadcasting Network (CBN) continues to argue that it's possible for gay people to alter their sexual orientation.

The topic of so-called “reparative” therapy, which seeks to alter the sexual orientation of gay people, is being talked about in the media amid accusations that Minnesota Rep. Michele Bachmann's family clinic Bachmann & Associates seeks to “cure” gay people.

In a segment broadcast on Wednesday, the CBN pointed to a 2007 study as proof that change is possible.

“I think our study raises that question again,” Psychologist Mark Yarhouse said on the program. “It says, 'Well, wait a minute. Here's a change effort sustained over time, and there's a pretty significant percentage of people for whom this was helpful.”

CBN claimed that 30 percent of the study's participants were able to “reduce their homosexual attraction enough to be celibate without distress” and 23 percent were able to “convert to opposite sex attraction.”

The segment further suggests that the American Psychological Association has endorsed the practice simply because it has not formally banned it.

“Some mainstream media are reporting that the American Psychological Association, or APA, has rejected so-called conversion therapy. But that's just not true. The APA has not banned it or even deemed it unethical,” the CBN reported. (The video is embedded in the right panel of this page.)

The APA, however, has rejected Yarhouse's study, saying it was “unpersuasive due to their study's methodological problems.”

“Best-practice analytical techniques were not performed in the study, and there are significant deficiencies in the analysis of longitudinal data, use of statistical measures, and choice of assessment measures,” the APA wrote in 2009.

At its 2006 annual meeting, the APA released the following statement: “For over three decades the consensus of the mental health community has been that homosexuality is not an illness and therefore not in need of a cure. … Our further concern is that the positions espoused by [“ex-gay” groups] NARTH and Focus on the Family create an environment in which prejudice and discrimination can flourish.”

Yarhouse's study was funded by the “ex-gay” group Exodus International and its research subjects were recruited with help from Exodus and NARTH.
