Narth

The Alliance for Therapeutic Choice and Scientific Integrity (ATCSI), also known as the NARTH Institute, is a United States organization that promotes conversion therapy, a pseudoscientific practice used in attempts to change the sexual orientation of people with same-sex attraction. ATCSI's promotion of conversion therapy as a scientifically supported therapeutic method is contradicted by overwhelming scientific consensus. ATCSI has not been recognized by any major United States–based professional association. No schools, universities or professional programs currently train its counselors in reparative therapy.
