Increasingly psychotherapy is being shown in relevant studies to be an effective form of treatment for mental disorders in its own right, despite frequent claims that evidence for its effectiveness in number of serious disorders is almost totally lacking. Moreover, studies have suggested that a combination of psychotherapy and appropriate medication may lead, in the case of at least some identifiable mental disorders, to significantly better outcomes compared to those in which medication is applied without the support of psychotherapy. This provides support for mental health professionals to consider psychotherapy when deciding on the treatment of patients suffering from mental disorders.
