Haldeman writes that psychoanalytic treatment of homosexuality is exemplified by the work of Irving Bieber ''et al.'' in ''Homosexuality: A Psychoanalytic Study of Male Homosexuals''. They advocated long-term therapy aimed at resolving the unconscious childhood conflicts that they considered responsible for homosexuality. Haldeman notes that Bieber's methodology has been criticized because it relied upon a clinical sample, the description of the outcomes was based upon subjective therapist impression, and follow-up data were poorly presented. Bieber reported a 27% success rate from long-term therapy, but only 18% of the patients in whom Bieber considered the treatment successful had been exclusively homosexual to begin with, while 50% had been bisexual. In Haldeman's view, this makes even Bieber's unimpressive claims of success misleading.<ref>{{Harvnb|Haldeman|1991|pp=150–151}}</ref>

Haldeman discusses other psychoanalytic studies of attempts to change homosexuality. Curran and Parr's "Homosexuality: An analysis of 100 male cases", published in 1957, reported no significant increase in heterosexual behavior. Mayerson and Lief's "Psychotherapy of homosexuals: A follow-up study of nineteen cases", published in 1965, reported that half of its 19 subjects were exclusively heterosexual in behavior four and a half years after treatment, but its outcomes were based on patient self-report and had no external validation. In Haldeman's view, those participants in the study who reported change were bisexual at the outset, and its authors wrongly interpreted capacity for heterosexual sex as change of sexual orientation.<ref>{{Harvnb|Haldeman|1991|pp=151, 256}}</ref>
