DISCUSSION
A variety of psychological treatments have been investigated in randomized trials in depressed primary care patients. CBT approaches have been tested most often. Overall, there is evidence that psychological treatments are superior to usual care alone, the size of the effects being small to moderate. Our analyses suggest that the differences between different types of psychological treatments are minor, and remote therapist-led, guided self-help, and minimal-contact approaches can yield effects similar to personalized face-to-face therapies. There are also hints that psychological therapies might be less effective for patients having minor depression and dysthymia than for patients with major depression.
