There have been a handful of studies examining the effects of other therapy delivery mechanisms besides traditional face-to-face work. Telephone based therapy has been one of the primary focuses, and a new study has shown that it can be effective at reducing depression.

At 18 months after the first session, 77 percent of the patients who received phone-based therapy reported that their depression was “much” or “very much” improved, compared with 63 percent of patients who received regular care.

I think that brief phone interventions can definitely be effective if the goal is simply to be an auxiliary piece to regular care or if there is a harder to reach population. However, I think more in-depth work may be hindered by the loss of human contact that comes from sitting in the same room with someone.
