a major British clinic set up in 1933 in Portman Square, London, by three psychoanalysts to assess, diagnose, and research delinquency. This led to the study and treatment of all mental and behavioral abnormalities and disorders. The clinic joined the Tavistock Clinic in the Tavistock and Portman National Health Service Trust in 1994. The trust provides a range of clinical mental health services as well as professional education and training.
