What Works Best? CBT or Meds for Anxiety, Depression…

30 Apr

Researchers from the Puget Sound Health Care System in Seattle, Washington conducted a meta-analysis on whether cognitive behavioral therapy is more efficacious than medication for depressive disorders vs. anxiety disorders.
 
The investigators selected randomized controlled studies comparing CBT and pharmacotherapy, with or without placebo, in adults with major depressive or anxiety disorders.

Twenty-one anxiety studies (N = 1,266) and twenty-one depression studies (N = 2,027) comparing medication to CBT were included. Including all anxiety disorders, the overall effect size was .25 (95% CI: -0.02, 0.55, P =.07).  Effects for panic disorder significantly favored CBT over medications (.50, 95% CI: 0.02, 0.98). Obsessive-compulsive disorder showed similar effects-sizes, though not statistically significant (.49, 95% CI: -0.11, 1.09). Medications showed a nonsignificant advantage for social anxiety disorder (-.22, 95% CI: -0.50, 0.06).

The overall effect size for depression studies was .05 (95% CI: -0.09, 0.19), with no advantage for medications or CBT.

Pooling anxiety disorder and depression studies, the omnibus comparison of the relative difference between anxiety and depression in effectiveness for CBT versus pharmacotherapy pointed to a nonsignificant advantage for CBT in anxiety  disorders, as opposed to depression (B =.14, 95% CI: -0.14, 0.43).

On balance, the evidence indicates that there are at most very modest differences in the effects of CBT versus pharmacotherapy in the treatment of anxiety, as opposed to depressive disorders.  On the other hand, there seems to be larger differences between the anxiety disorders in terms of their relative responsiveness to pharmacotherapy versus CBT.
