In 1910, the first college mental health service sought to help college students with personality development and building a healthy mind. In 1920, the meeting that founded the American College Health Association (ACHA) identified "mental hygiene" as important, although a separate Mental Health Section was not established in ACHA until 1957. Between 1920 and 1960, a series of national meetings helped define the role and functioning of college mental health and counseling services. Most colleges employed a multidisciplinary staff of psychologists, psychiatric social workers, and psychiatrists to provide clinical services for students and consultation and education for faculty and staff. Mental health services on college campuses grew rapidly in the 1960s and 1970s, leading to discussions in the late 20th century of the use of brief psychotherapies, prevention and treatment of drug and alcohol abuse, prevention of suicide and homicide, the use of psychotropic medications, and effective campus interventions.
