Behavioral therapy (ingl. behavior - "behavior"). In 1913, American psychologist John Watson (1878-1958) published his first article on behaviorism. He wrote: "If you want to change a person's mind and spirit, first change his behavior." Based on this idea, behavioral psychotherapy was formed and in the 50s and 60s of the 20th century, it was widely used and recognized in the correction of behavioral disorders in adolescents. This therapy is highly effective in adolescents with behavioral changes, but less effective in older adults. Behavioral therapy is aimed at correcting pathologically changed behavior and forming correct lessons for it. During behavioral therapy, every form of behavior in a teenager is analyzed and corrected.

Pathological changes in behavior are "replaced" with healthy behavioral qualities during psychotherapeutic procedures conducted step by step. Therefore, behavioral therapy does not work on the causes of behavior change, but directly changes pathological behavior for the better. As healthy behavior and self-control skills are formed, the thinking in him changes, the teenager gains self-confidence, his lifestyle changes and social adaptation is achieved.
