Published in 1980, the DSM-III represented a major shift in the classification of mental disorders. It introduced a much greater level of detail in the descriptions of disorders compared to its predecessors. This edition also saw a significant expansion in the scope of the manual, growing to include 265 diagnoses within its 886 pages, a substantial increase from the 106 diagnoses in DSM-I.

The rise of DSMIII

It was a vastly different manual. Centered descriptive criteria, removed etiological theory, presented psychiatry in a medical model, and emphasize follow-up and family histories. 

Attempted to remove all evidence of earlier psychodynamic explanations for disorders and framed diagnostic categories according to symptom clusters and patterns. 

Changes made 

After homosexuality was removed as a disorder, the DSM-III introduced a new diagnosis called 'ego-dystonic homosexuality.' This classification applied to individuals distressed by their same-sex arousal, particularly when it conflicted with a desire for heterosexual relationships. Widely seen as a compromise to appease those who still viewed homosexuality as an illness, this controversial diagnosis was ultimately removed from the revised DSM-III-R in 1986.
