From Psychiatric Textbooks to Legislative Bans: Is Conversion Truth for Families Mapping the Full Picture?

A practice that began inside institutional psychiatry, survived clinical repudiation, migrated into religious frameworks, and is now the subject of criminal legislation across multiple countries represents a particularly complex kind of history to document accurately. Conversion Truth for Families, a research-backed educational hub for parents and caregivers, has produced one of the more thorough accounts of that trajectory — tracing conversion therapy from its 19th-century origins through the modern wave of bans and the rebranding efforts now drawing regulatory attention.

Richard von Krafft-Ebing’s 1886 Psychopathia Sexualis is the usual starting point. His clinical framework classified same-sex attraction as a pathological condition and shaped medical thinking in Europe and the United States for decades. The American psychoanalytic tradition hardened that framework significantly. Sandor Rado’s 1940 theoretical work argued that heterosexuality was the only biologically sound orientation, feeding directly into Irving Bieber and colleagues’ 1962 study, which claimed that 27% of gay men in psychoanalysis had achieved conversion. That study was later found to be compromised by selection bias and dependent on analyst-reported outcomes that no independent review could verify.

Behavioral psychology produced methods that were more direct. Chemical aversion therapy. Electrical aversion therapy. Alan Turing was subjected to chemical castration in 1952 as a legal penalty for homosexuality. He died two years later. Masters and Johnson’s 1979 study claimed a 71.6% conversion success rate. A 2012 investigation by The Atlantic found no patient records from that period that could confirm those outcomes. No major medical organization treats the study as credible evidence today.

Douglas Haldeman’s 1994 review in the Journal of Consulting and Clinical Psychology examined three decades of research on sexual orientation change efforts and found the same methodological problems recurring across studies: self-selected samples, no control groups, outcomes measured in behavioral terms rather than in actual attraction. His review established a documented pattern of failure that subsequent research extended and deepened.

The APA’s December 1973 vote to remove homosexuality from the DSM was the most significant institutional event in conversion therapy’s clinical history. It was made possible by Dr. Evelyn Hooker’s 1957 research, which demonstrated that trained clinicians could not reliably distinguish between the psychological profiles of gay and heterosexual men. But declassification alone did not end conversion practice. The DSM-III in 1980 included a category — ego-dystonic homosexuality — that preserved a clinical rationale for orientation-change interventions until its removal in 1987. The Williams Institute estimated in 2019 that 698,000 LGBTQIA+ adults in the United States had been subjected to conversion therapy, with around 350,000 having received it as minors.

The harm data compiled since then is extensive. The APA’s 2009 Task Force found no high-quality evidence of lasting orientation change in its review of 83 peer-reviewed studies, while documenting associations with depression, anxiety, and suicidal ideation. A 2020 study in JAMA Psychiatry linked recalled conversion exposure with elevated distress and lifetime suicide attempts among transgender adults. The Family Acceptance Project found a 63% suicide attempt rate among youth subjected to combined parental and clinical conversion interventions, compared to 22% for those without such exposure. SAMHSA’s 2023 report stated plainly that these efforts in children and adolescents are harmful and should never be provided.

Robert Spitzer’s public retraction of his own 2003 study and his apology to those who had spent years in what he termed useless attempts to change gave the evidentiary collapse a personal face.

Conversion Truth for Families addresses the rebranding problem that legislative bodies are now working to close — the use of new terminology such as “sexual attraction fluidity exploration in therapy” or “reintegrative therapy” for interventions that are functionally equivalent to what the bans prohibit. The APA’s 2021 resolution confirmed that voluntary consent does not resolve questions about evidence or documented risk. More than 23 states and the District of Columbia had enacted minor-focused bans by early 2026. Canada criminalized the practice nationally in 2021. The WHO called for global elimination in 2023.
