Step-by-step explanation:
The question pertains to behavior therapies and the statement that is true among the provided options. Behavior therapies are more action-oriented and are concerned with changing behaviors rather than fostering insight or self-awareness. Therefore, the most accurate statement is (D) they assume that insight is irrelevant to the goal of treatment. These therapies focus on modifying dysfunctional behaviors through techniques such as reinforcement, punishment, and modeling. Behavior therapy does not typically concern itself with underlying thoughts or emotions unless those thoughts and emotions are directly leading to the maladaptive behavior.
Cognitive-behavioral therapy, however, is a type of therapy that combines both the behavioral and cognitive perspectives. It aims to change both cognition and behaviors that are contributing to a person’s problems. It is grounded in the idea that our thoughts, feelings, and behaviors are interconnected and that changing one can change the others.
The effectiveness of therapy approaches such as hypnosis and cognitive therapy depends on various factors, including the commitment of the individual to change their thinking and behavior. Hypnosis, for example, is most effective in individuals that are very open to the power of suggestion.
