The LDS couples profiled on TLC's "My Husband Is Not Gay" may find these statistics sobering: Marriages like theirs — same-sex attracted husbands and straight wives — are two to three times more likely to end in divorce than others.

That finding and others come from a newly released in-depth survey of 1,612 self-selected LGBT/same-sex attracted Mormons and former Mormons, thought by researchers to be the largest study ever conducted with this population.

Rather than tapping a random sample, John Dehlin, a doctoral student at Utah State University, and Bill Bradshaw, a retired Brigham Young University professor, with help from Renee Galliher, also of USU, solicited responses via various websites, including pro-Mormon outlets such as North Star International and those more critical such as Dehlin's own "Mormon Stories" podcast.

The study found that:

• Between 51 percent and 69 percent of mixed-orientation Mormon marriages end in divorce, well above the roughly 25 percent of LDS couples who split up.

• More than 70 percent of LGBT/same-sex attracted Mormons leave the LDS Church.

• 80 percent of respondents reported undergoing efforts to change their sexual orientation — 85 percent of which were religious and private efforts, 31 percent were private efforts only, 40 percent therapist-led and 21 percent group efforts.

• 53 percent rejected their religious identity; 37 percent compartmentalized their sexual and religious identities; 6 percent rejected their LGBT identity; 4 percent integrated the two.

The study relied on participants in 48 states (45 percent in Utah) and 22 countries; 75 percent were male, 22 percent female; 91 percent were white; 7 percent were excommunicated from The Church of Jesus Christ of Latter-day Saints, 25 percent had resigned, 36 percent were inactive, 29 percent were active, and 3 percent had been disfellowshipped.

Forty-two percent were single, 35 percent were in committed same-sex relationships, and 16 percent were married in a heterosexual relationship.

The process of finding respondents, known as "snowballing," while not scientific, is a respected way to study certain issues and populations, Dehlin says. "We worked hard to avoid any bias."

Others familiar with LGBT Mormons confirmed the results in their own research.

Kendall Wilcox, who has collected more than 300 narratives from LGBT Mormons and their families for his documentary film project, "Far Between," also has noted that mixed-orientation marriages are far more likely to fail than their counterparts.

Still, the study's self-selection, Wilcox says, "can skew the data."

Those whose mixed-orientation marriages ended experience "a kind of triple blame by their family and faith communities — first for being gay, then for having ruined the lives of their spouses and children by ... marry[ing] in the service of trying to 'overcome' their homosexuality, and then finally for having failed in the marriage and 'given up,' " he says. "They want their story to be known and not repeated; they want vindication for their mistreatment."

Study respondents who are "heavily invested in their [mixed-orientation marriages'] success" want their perspective publicized, Wilcox says. "Not only do they want their marriages to succeed for personal and religious reasons but they are also professionally invested in their propagation."

The couples who are "doing just fine and have nothing to prove often remain silent," he says. "Therefore, we don't know their numbers and don't know how their numbers compare to the 'failed' mixed-orientation marriages."

The survey also concluded that many more LDS gays try "personal righteousness" efforts — prayer, fasting, church activity, temple worship and strict observance of the LDS health code — as a way to change their orientation than those who seek psychological interventions such as the discredited "reparative therapy."

None of it worked, Dehlin says. "Zero percent of participants were able to eliminate same-sex attraction." And they were psychologically damaged by trying.

Though the LDS Church says being homosexual is not a sin, only acting on it is, the Utah-based faith offers its gay members two options: Remain celibate or marry someone of the opposite sex.

The study characterized these members' coping efforts in four ways: denial of their sexuality, rejecting their religion, compartmentalizing their sexuality and their faith or integrating the two.

The survey found — and Wilcox's research confirmed — that the more Mormon and the more same-sex attracted a person is (on the Kinsey scale), the more prone that person is to depression and suicide.

"The conflict is at its highest in these sorts of people," Wilcox says.

The most psychologically healthy outcomes were experienced by those who could openly balance their faith with their sexuality, Dehlin notes. "But not many people can do it."

For Bradshaw, some of the most moving responses to the survey were in response to the question: Have you ever had an experience that you attribute to deity in which you have felt acceptance of your sexuality?

Many respondents shared personal stories of spiritual experiences in which they felt the "overwhelming love of God, which did not require some sort of change in their sexual orientation."

If these experiences were on any other subject, the retired BYU researcher says, "they would have been featured in the [LDS Church's] Ensign [magazine]."
