Cognitive behavioral therapy (CBT) is a form of psychotherapy that helps patients challenge their negative thought patterns and develop healthier behavior patterns.

This form of therapy is effective for several forms of depression and anxiety. A review published on February 22, 2017 in JAMA Psychiatry, concluded that patients can successfully use an online form of CBT to reduce symptoms of depression.

This approach offers an effective low-cost alternative to therapy that is readily accessible to patients who need help.

The review included more than 3,800 depressed volunteers from 13 studies on self-guided Internet-based therapy compared to alternative treatments or a placebo.

Those who used online CBT were significantly more likely to improve their depression than those who received other treatments, got care from a doctor, were put on a waiting list, or received placebo.
