CBT is a valuable treatment for mild, moderate, and severe forms of major depression. It is equally effective and more durable than medication alone, and the combination of medication and CBT may increase the response rate and extend durability when CBT is employed after pharmacotherapy is successful. Therapist competence has been shown to influence outcomes in CBT for depression. Practitioners who wish to learn more about CBT may access a wide variety of educational materials: basic texts, course offerings at major scientific meetings, and local and national training centers are available. The Academy of Cognitive Therapy website (www.academyofct.org) provides detailed information about obtaining training and certification in CBT.
