A good analysis, I completely agree. The question of good or bad might be better directed at the client end rather than the therapist end when assessing effectiveness. So long as the core of the intervention remains CT, does it really matter that much if some therapist introduce an eclectic approach. It would seem some people take the purest approach which does not allow for the client to relate in their own terms, in some cases clients need to move outside the constrictions of any one single approach.
