The main goal of behavior therapy is to

A) alter the client's brain chemistry by prescribing specific drugs.
B) change the client's thought patterns so that negative emotions can be controlled.
C) alter the problematic behaviors and maladaptive habits of the client.
D) identify the early childhood unconscious conflicts that are the source of the client's symptoms.

The primary focus of behavior therapy is to address and modify the specific behaviors and habits that are causing difficulties for the client. This is typically achieved through the use of techniques such as reinforcement, punishment, and modeling. While medication may sometimes be used in conjunction with behavior therapy, altering brain chemistry is not the primary goal. Similarly, changing thought patterns (which is a focus of cognitive-behavioral therapy, rather than behavior therapy) and identifying early childhood conflicts are not the main objectives of behavior therapy.
