It’s a question as old as therapy itself, and one insurance adjusters are keen to answer. I have always thought that most studies come up with about a 50% success rate… similar to a placebo.
The most significant difference in patient outcomes, Wampold says, almost always lies in the skills of the therapist, rather than the techniques they rely on. Hundreds of studies have shown that the strength of the patient-therapist bond — a patient’s sense of safety and alignment with the therapist on how to reach defined goals — is a powerful predictor of how likely that patient is to experience results from therapy. But what distinguishes the therapists most likely to forge those bonds is not intuitive. Wampold says that some of the attributes that would seem most salient — a therapist’s agreeability, years of training, years of experience — do not correlate at all with effectiveness of care.
Maybe it’s the relationship that matters, not the discipline.
