The dissemination of efficacious psychological treatments.

I concur with Dr. Garfield that therapist, client, and common treatment factors are important and are often likely to explain significant outcome variance. I disagree with him in terms of whether the existence of such other outcome predictors should lead to a decision not to disseminate efficacious treatments. The list of examples of empirically validated treatments by the American Psychological Association Division 12 Task Force was not an effort at minimizing the importance of such client, therapist, and common factors but rather an attempt to help disseminate what has been learned regarding treatments. The list of empirically validated treatments is fully compatible with an eclectic approach. I conclude with the recommendation that dissemination of empirically validated treatments is probably most successfully done through training programs.
