The changing view of homosexuality
In the 1950s and 1960s, some therapists used aversion therapy in an attempt to cure male homosexuality which they saw as an illness. This typically involved showing pictures of naked men to patients while giving them electric shocks or drugs to make them vomit. These methods proved entirely ineffective.
Homosexuality was listed as a mental disorder when the first American list of disorders (DSM) was published in 1968. In 1973, the American Psychiatric Society who publish this list voted on whether they believed homosexuality to be a mental disorder. 5845 psychiatrists voted to remove it from DSM and 3810 voted to keep it.
Homosexuality was removed but replaced with ‘sexual orientation disturbance’ for people ‘in conflict with’ their sexual orientation.
Finally, in 1987, homosexuality was completely taken out of the list.
Meanwhile, the World Health Organisation only removed homosexuality from its classification (the ICD-10) published in 1992.
This highlights that concepts of mental disorder can rapidly evolve as society changes.
