Which of the following disorders is LEAST likely to be successfully treated by cognitive-behavioral therapy?

A) schizophrenia
B) depression
C) require less effort from the client
D) obsessive-compulsive disorder

Answer: A
Rationale: While cognitive-behavioral therapies have been successful in treating such conditions as OCD, obesity, and eating disorders, and depression. Cognitive and behavioral therapies alone may not alter the numerous problem behaviors associated with a major disorder. For example, behavioral therapy may be used to help individuals with schizophrenia cope with auditory hallucinations, but it does not eliminate them.
