Since the founding of the Church of Scientology in 1954 by L. Ron Hubbard, the relationship between Scientology and psychiatry has been dominated by strong opposition by the organization against the medical specialty of psychiatry, and of psychology, with themes relating to this opposition occurring repeatedly throughout Scientology literature and doctrine. According to the Church of Scientology, psychiatry has a long history of improper and abusive care. The group's views have been disputed, criticized and condemned by experts in the medical and scientific community and been a source of public controversy.
