A simple type of psychotherapy known as behavioral activation is not inferior to the gold-standard cognitive behavioral therapy (CBT) in reducing depression symptoms, found one of the largest trials of psychological treatment for depression to date (Richards DA et al. Lancet. doi:10.1016/S0140-6736(16)31140-0 [published July 22, 2016]). The authors also note that there may be a health care cost advantage to behavioral activation because it can be delivered by mental health workers with no formal training in psychological therapies.
