The terms cognitive-behavioral therapy (CBT) and behavioral therapy are often used interchangeably together in the field. However, there is a clear distinction between the two therapies regarding therapy techniques and approaches. Typically, behavioral therapy focuses on manipulating the patient's external environment and internal physiological environment to cause the desired behavior change. It employs several methods such as social skills training, habit reversal training, observational learning, behavior modification to achieve the change. By contrast, cognitive-behavioral therapy (CBT) considers thinking as the main factor for change. The treatment seeks to evaluate the validity of the patients' thoughts and beliefs. The therapist also seeks to establish and assess what the patient expects and predicts and their attributions for causes of events.
