Reality therapy (RT) is an approach to psychotherapy and counseling developed by William Glasser in the 1960s. It differs from conventional psychiatry, psychoanalysis and medical model schools of psychotherapy in that it focuses on what Glasser calls "psychiatry's three Rs" – realism, responsibility, and right-and-wrong – rather than mental disorders. Reality therapy maintains that most people suffer from socially universal human conditions rather than individual mental illnesses, and that failure to attain basic needs leads to a person's behavior moving away from the norm. Since fulfilling essential needs is part of a person's present life, reality therapy does not concern itself with a person's past. Neither does this type of therapy deal with unconscious mental processes.
