Homosexuality is Not a Pathology
1) Professional Opinions
One of the primary turning points in the official acceptance of the healthy mental status of homosexuals came in 1973 when the American Psychiatric Association voted to remove homosexuality from the DSM-IV, the primary tool used by psychiatrists to diagnose patients with various mental illnesses.
Historically, psychoanalysts have been the primary opponents to the depathologization of homosexuality in the 1973 APA decision, Socarides and Bieber being by far the most vocal opponents of the decision. However, in a recent survey of psychoanalysts (n=82; Friedman) they found that “no respondents strongly endorsed the type of pathological model proposed by Socarides” (p. 84), and that “the responses of the group as a whole were more towards a health than illness model.”
2) Gay Relationships
a) 40-60% of gay men, and 45-80% of lesbians are in a steady relationship
b) Studies of older homosexual people show that gay relationships lasting over 20 years are not uncommon
c) In a large sample of couples followed for 18 months the following “break up” statistics were observed: lesbians=22%, gay=16%, cohabiting heterosexuals=17%, married heterosexuals=4%
d) Homosexual and heterosexual couples matched on age, etc, tend not to differ in levels of love and satisfaction, nor in their scores on other standardized scales
e) gay/lesbian parents report no greater stress than heterosexuals, and children are not adversely affected by being raised by homosexual families
3) Homosexuals are no more promiscuous or predatory than heterosexuals
Statistical research indicates that gay men may have fewer number of sexual partners than heterosexuals.
c) Homosexuals are NOT more likely to be child molesters. In a random sample of 175 child sex offenders 76% report having exclusive adult heterosexual behavior, and 24% report having adult bisexual behavior. The sexual attraction towards children is a pathology unrelated to sexual orientation.
4) Psychological Testing Affirms the Mental Health of Homosexuals
This represents the evidence that homosexuality is not pathological, and comes from studies that were primarily done in the 60’s, 70’s and 80’s. There were a flurry of studies done after the classical study by Evelyn Hooker in 1957, which produced the large body of studies from the 60’s -70’s. Then the studies dwindle down as the 80’s progress, and very few studies can be found in the 90’s. This is because all of the evidence is convergent, so no further studies were warranted, and the conclusion was that homosexuality evidenced no pathological characteristics that were significantly different from heterosexuals.
