Psychotherapy involves various approaches to treating mental disorders and improving mental well-being. Some major types discussed are psychodynamic therapies, which aim to help clients gain insight into problem behaviors by exploring unconscious dynamics. Approaches include Freud's traditional psychoanalysis using free association and dream analysis, as well as dissident theories from Jung, Adler, and Horney emphasizing individuation, social factors, and basic anxiety. Biomedical therapies can include electroconvulsive therapy, psychosurgery, and various psychiatric drugs to treat conditions like depression and schizophrenia. Money availability, client characteristics, and treatment location all impact who receives therapy.
