Cognitive therapy was created because experimental psychology and behaviorism could not satisfactorily explain complex behaviors and the development of cognitive functions, while psychoanalysis was criticized for insisting on unconscious, long-term therapy, the interpretation of transference as a key therapeutic technique to voluntarily produce in the assessment of treatment outcomes. The goal of this therapeutic system is to teach the patient to bear the symptoms and not pay attention to them and/or to solve problems by correcting errors and misconceptions in the processes of interpretation, evaluation, understanding, conclusion and decision-making, as well as changing certain assumptions that the patient has about themselves, others, their environment, past or future and which are believed to contribute to the appearance and/or maintenance of psychological disorders. Cognitive therapy is used in the treatment of depression, stress, generalized anxiety, behavioral disorders in children and adolescents, in the treatment of problems in partner and family relationships, etc.
