The goal of behavior modification is to change clients' maladaptive or undesirable behaviors. Behavior modification is a psychological treatment approach that focuses on changing problematic behaviors by reinforcing desirable behaviors and reducing the reinforcement of undesirable behaviors. It involves identifying the specific behaviors that need to be modified, setting goals for behavior change, and using techniques such as positive reinforcement, punishment, and extinction to modify the behaviors. The goal of behavior modification is not to repair troubled or broken relationships, unearth the origin of maladaptive behavior, or modify the clients' personality structure. These may be addressed as part of the treatment process, but they are not the primary focus of behavior modification.
