Although the first student health service is credited to Amherst College in 1861, almost 50 years passed before Princeton University established the first mental health service in 1910. At that time, a psychiatrist was hired to help with student personality development. Although other schools subsequently established such services, the first 50 years of college mental health were marked by a series of national conferences. At the American Student Health Association's annual meeting in 1920, "mental hygiene" was identified as critical for college campuses to assist students to reach their highest potential. However, it took another 40 years before mental health and psychological counseling services became common on college and university campuses. The American College Health Association formed a Mental Health Section to serve mental health professionals in 1957, and most colleges and universities have now developed mental health and counseling programs commensurate with the size of their student bodies.
