Summary

Cognitive behavioral therapy (CBT) has the strongest evidence base of all the psychological treatments for depression. It has been shown to be effective in reducing symptoms of depression and preventing relapse. All models of CBT share in common an assumption that emotional states are created and maintained through learned patterns of thoughts and behaviors and that new and more helpful patterns can be learned through psychological interventions. They also share a commitment to empirical testing of the theory and clinical practice. Beck’s Cognitive Therapy sees negative distorted thinking as central to depression and is the most established form of CBT for depression. Behavioral approaches, such as Behavioral Activation, which emphasize behavioral rather than cognitive change, also has a growing evidence base. Promising results are emerging from therapies such as Mindfulness Based Cognitive Therapy (MBCT) and rumination-focused therapy that focus on the process of managing thoughts rather than their content. Its efficacy-established CBT now faces the challenge of cost-effective dissemination to depressed people in the community.
