    Online programs to fight depression are already commercially available. While they sound efficient and cost-saving, a recent study reports that they're not effective, primarily because depressed patients are not likely to engage with them or stick with them.

The study looked at computer-assisted cognitive (认知的) behavioral therapy (CBT) and found that it was no more effective in treating depression than the usual care patients receive from a primary care doctor.

Traditional CBT is considered an effective form of talk therapy for depression, helping people challenge negative thoughts and change the way they think in order to change their mood and behaviors. However, online CBT programs have been gaining popularity, with the attraction of providing low-cost help wherever someone has access to a computer.

A team of researchers from the University of York conducted a randomized (随机的) control trial with 691 depressed patients from 83 physician practices across England. The patients were split into three groups: one group received only usual care from a physician while the other two groups received usual care from a physician plus one of two computerized CBT programs. Participants were balanced across the three groups for age, sex, educational background, severity and duration of depression, and use of antidepressants(抗抑郁药).

After four months, the patients using the computerized CBT programs had no improvement in depression levels over the patients who were only getting usual care from their doctors.

"It's an important, warning note that we shouldn't get too carried away with the idea that a computer system can replace doctors and therapists," says Christopher Dowrick, a professor of primary medical care at the University of Liverpool. "We do still need the human touch or the human interaction, particularly when people are depressed. "

"Being depressed can mean feeling lost in your own small, negative, dark world," Dowrick says. Having a person, instead of a computer, reach out to you is particularly important in fighting that sense of isolation. "When you're emotionally fragile, you're even more in need of a caring human being," he says.
