How does behavior therapy differ from other forms of psychotherapy?

A) It is concerned primarily with helping people to achieve self-understanding and to live a fuller, richer life.
B) It is content to change the problem behaviors even without understanding their underlying causes and origin.
C) It can be conducted by someone with no special training in psychology.
D) It is used only with children, not with adults.

Behavior therapy focuses on changing specific problem behaviors, rather than delving deeply into the individual's psyche or addressing underlying causes. This sets it apart from other forms of psychotherapy that may prioritize self-understanding or uncovering root issues. Additionally, behavior therapy requires specialized training and knowledge in the principles of behaviorism, so it cannot be conducted by just anyone.
