The one form of psychotherapy found to be helpful in treating schizophrenia is

A) humanistic therapy.
B) interpersonal psychotherapy.
C) behaviour therapy.
D) cognitive-behaviour therapy.
E) psychoanalysis.

Cognitive-behaviour therapy has been found to be the most effective form of psychotherapy for treating schizophrenia. It focuses on identifying and changing negative thought patterns and behaviours, which can help individuals manage their symptoms and improve their overall functioning. Other forms of therapy, such as humanistic therapy and psychoanalysis, have not been shown to be effective for treating schizophrenia. Interpersonal psychotherapy may be helpful for addressing social and relationship problems, but is not specifically targeted at treating the symptoms of schizophrenia. Behaviour therapy may also be helpful, but its effectiveness is often limited to specific symptoms, such as hallucinations or delusions.
