Of particular interest is that the report lauds the so-called "evidence-based psychotherapies" - code for those therapies which are "supported" by the incredibly weak psychotherapy outcome studies. One critic, Peter Roy-Byrne, M.D, summed up the criticisms of the report as follows:" In medicine, there is usually an array of different treatments for the same condition because of individual variability that is still poorly understood. Yet the field of medicine does not spend its time trying to understand what are the common elements between various effective treatments, though it will often explore comparative effectiveness as a way of improving care. It may well be that different kinds of individuals and problems demand different psychotherapeutic approaches rather than that there is one elemental Holy Grail that will be best for everyone.”
Of note is that, at least if you believe in free will as I do, patients always can choose to either respond favorably or unfavorably to any intervention a therapist makes. It is just not all that predictable, because everyone can choose to respond differently. In fact, the very same intervention given to seemingly very similar patients can lead to responses that are completely opposite from each other - in one case the patient improves on some dimension, while in the next the patient may get worse! In psychotherapy, patients are very different from one another in ways that vastly outnumber individual differences that affect treatment outcomes in any other field of medicine.
