Dimidjian, S., Hollon, S.D., Dobson, K.S., Schmaling, K.B., Kohlenberg, R., Addis, M., Gallop, R., McGlinchey, J., Markley, D., Gollan, J.K., Atkins, D.C., Dunner, D.L., & Jacobson, N.S. (2006). Randomized trial of behavioral activation, cognitive therapy, and antidepressant medication in the acute treatment of adults with major depression. Journal of Consulting and Clinical Psychology 74 (4), 658-670.

A 2006 issue of the Journal of Consulting and Clinical Psychology published the results of a remarkable clinical trial that showed that Behavioral Activation performed as well as a standard Cognitive-Behavior Therapy protocol. With these results, people want to know more about BA.

In 1996 the late Neil S. Jacobson and colleagues compared BA and cognitive-behavioral therapy for depression. While cognitive therapy was a much more complex treatment, the researchers found no significant differences in benefits between the treatments. Following that study Jacobson and colleagues launched the largest ever single site depression treatment study: they compared BA, Cognitive Therapy, and Antidepressant medications. The results: BA outperformed cognitive therapy in the acute treatment phase for moderately to severely depressed adults, and performed as well as antidepressant medication
