In 2008, the Royal College of Psychiatrists stated: "The Royal College shares the concern of both the American Psychiatric Association and the American Psychological Association that positions espoused by bodies like the National Association for Research and Therapy of Homosexuality (NARTH) in the United States are not supported by science. There is no sound scientific evidence that sexual orientation can be changed. Furthermore so-called treatments of homosexuality as recommended by NARTH create a setting in which prejudice and discrimination can flourish."
