The National Committee for Mental Hygiene (NCMH) in collaboration with the American Medical Psychological Association, which will later become the American Psychological Association (APA), proposes a plan for gathering uniform statistics in psychiatric hospitals and introduces the first classifications for "mental disease," proposing the rubric of “psychosis with constitutional psychopathic inferiority.”

In 1934, this term will shift to “psychopathic personality,” with specific attention paid to "pathological sexuality and emotionality" and "asocial and amoral trends" (Ozarin, 2011).
