Timeline of removal of homosexuality from DSM:
- 1952: DSM I listed homosexuality as a sociopathic personality disturbance.
- 1968: DSM II reclassified homosexuality as a sexual deviancy. Gay protestors began picketing the APA annual conventions.
- 1973: It was decided to replace homosexuality by “sexual orientation disturbance” in DSM III. This was passed in a referendum with 58% approval in 1974.
- DSM III replaced homosexuality with “ego-dystonic sexual orientation”.
- “Ego-dystonic sexual orientation” was removed from DSM III-R.
Many medical professionals continue to be homophobic, and the problem is far from solved.
