Earlier this month, psychiatrist Bob Spitzer made headlines after he retracted his controversial 2001 study proclaiming that "highly motivated" gay and lesbian people could change their sexual orientation. But Spitzer is now going even further by making what has been described as "an unprecedented apology" to both former patients of reparative therapy as well as members of the lesbian, gay, bisexual and transgender (LGBT) community at large.

Truth Wins Out has obtained a copy of the letter, addressed to Dr. Ken Zucker:

" The Fatal Flaw in the Study –- There was no way to judge the credibility of subject reports of change in sexual orientation. I offered several (unconvincing) reasons why it was reasonable to assume that the subject’s reports of change were credible and not self-deception or outright lying. But the simple fact is that there was no way to determine if the subject’s accounts of change were valid.

I believe I owe the gay community an apology for my study making unproven claims of the efficacy of reparative therapy. I also apologize to any gay person who wasted time and energy undergoing some form of reparative therapy because they believed that I had proven that reparative therapy works with some “highly motivated” individuals."

The now 80-year-old Spitzer, who had ironically led the effort to declassify homosexuality as a mental illness in 1973, told American Prospect earlier this month that earlier critiques of his study were "largely correct."

He continued, “The findings can be considered evidence for what those who have undergone ex-gay therapy say about it, but nothing more." After noting that failed attempts to rid oneself of homosexual attractions "can be quite harmful," he then requested writer Gabriel Arana print a retraction of the 2001 study, "so I don’t have to worry about it anymore."

In the article, Arana also claimed to have undergone therapy for over three years with Dr. Joseph Nicolosi, co-founder and former president of the National Association for the Research and Therapy of Homosexuality (NARTH), in an effort to change his own sexual orientation.

Take a look at recent cases of reported "ex-gay" therapy below:

  • Bachmann's Alleged Involvement

    In July,gay advocacy group Truth Wins Out released video footage allegedly shot undercover at the Christian-affiliated Minnesota clinic owned by Michele Bachmann and her husband, and claimed to find evidence of conversion therapy being performed on the premises. "Michele Bachmann wants to be in the Oval Office and wants to be the president of the United States," Wayne Besen, "It's important to know what her true beliefs are and what goes on in this clinic."

  • 'Gay Barbarian Horde' Invades Bachmann's Clinic

    Last July activists dressed as "gay barbarians" traveled to Bachmann's clinic to protest its alleged "pray the gay away" practices. <a href="http://www.huffingtonpost.com/2011/07/21/michele-bachmanns-glitter-prank_n_906165.html" target="_hplink">A press release issued by the group reads:</a> <blockquote>Today a horde of gay barbarians descended upon Michele and Marcus Bachmann's "pray away the gay" clinic and demanded that Marcus come out and discipline them for their "deviant" behavior. Marcus Bachmann, who conducts "reparative therapy" at the clinic intended to convert homosexuals, has said that gays are "barbarians who need to be disciplined." The horde requested to speak directly with Bachmann and experience some "discipline" for themselves. When Marcus was no where to be found, the barbarians glittered the empty waiting room and reception area while chanting, "You can't pray away the gay -- baby, I was born this way!" The action was organized by the same young man who threw glitter on Newt Gingrich, starting a national trend in political protest of anti-LGBT sentiments from political candidates and campaigns. "Michele and Marcus Bachmann think gay people are barbarians?" asked LGBT activist Nick Espinosa. "I think its clear to everyone who the real barbarians are, based on the Bachmanns' archaic views on LGBT equality."</blockquote>

  • Gay Conversion Therapy Victim Comes Forward

    Earlier this month, "I'm From Driftwood" featured a video interview with Samuel Brinton, who was raised in rural Iowa and subjected to forced Christian conversion therapy. "We then went into the 'Month of Hell,'" Brinton explained. "The 'Month of Hell' consisted of tiny needles being stuck into my fingers and then pictures of explicit acts between men would be shown and I'd be electrocuted."

  • Prominent 'Ex-Gay' Doctor Retracts Claims Made In Key Gay Conversion Therapy Study

    This week the psychiatrist who published a controversial 2001 study proclaiming that "highly motivated" gay and lesbian people could change their sexual orientation <a href="http://www.huffingtonpost.com/2012/04/11/robert-spitzer-ex-gay-psychiatrist-retraction_n_1417679.html?ref=gay-voices" target="_hplink">retracted his initial claims.</a> Psychiatrist Bob Spitzer, who had ironically led the effort to declassify homosexuality as a mental illness in 1973, told American Prospect that he now wants to retract his study, while addressing several of the ample criticisms against its findings. "In retrospect, I have to admit I think the critiques are largely correct," said the 80-year-old Spitzer, who is now retired and suffering from Parkinson's disease. "The findings can be considered evidence for what those who have undergone ex-gay therapy say about it, but nothing more."

  • John Smid Discusses 'Praying The Gay Away' With Chris Matthews

    The former director of the ex-gay Christian ministry Love in Action <a href="http://www.huffingtonpost.com/2011/10/20/john-smid-former-ex-gay-minister-sexual-orientation-_n_1022417.html#s423190&title=Gay_Conversion_Therapy" target="_hplink">came forward last October</a> to say that not only that he is gay, but that he believes it is impossible to change one's sexual orientation. Though Smid admitted he did "experience homosexuality" on the show, he arguably stopped short of embracing his sexual orientation. "I would say predominately, I am attracted to men," he said. "At the same time, I've chosen to be married [to a woman] and a lot of people make that choice."

  • Not Born This Way?

    Richard Cohen, director of the International Healing Foundation and author of "Coming Out Straight" and "Gay Children, Straight Parents," believes that people can change. "There is no credible scientific evidence to suggest either a genetic or biologic basis for homosexual desires in men or women," he said. "So people are not born this way...it's always a confounding of many different factors that lead people to experience these desires...people don't choose this, the choice is: do they want to lead that life, or do they want to change?"

  • Gay To Straight With Prayer?

    In an appearance on "Dr. Drew" earlier this year, psychologist Joseph Nicolosi -- a founding member of the National Association for Research & Therapy of Homosexuality (NARTH) -- said he continues to support conversion therapy: "People can change, people have a choice, people should be given a choice," he said. "If a person chooses to exercise his heterosexual potential...we provide that therapy...it doesn't work for all people, but it works for some."
