... (M)many patients are subjected to a kind of dim-sum approach — a little of this, a little of that, much of it derived more from the therapist’s biases and training than from the latest research findings. And even professionals who claim to use evidence-based treatments rarely do. The problem is called “therapist drift.”

“A large number of people with mental health problems that could be straightforwardly addressed are getting therapies that have very little chance of being effective,” said Glenn Waller, chairman of the psychology department at the University of Sheffield and one of the authors of the meta-analysis.

A survey of 200 psychologists published in 2005 found that only 17 percent of them used exposure therapy (a form of C.B.T.) with patients with post-traumatic stress disorder, despite evidence of its effectiveness. In a 2009 Columbia University study, research findings had little influence on whether mental-health providers learned and used new treatments. Far more important was whether a new treatment could be integrated with the therapy the providers were already offering.

The problem is not confined to the United States. Two years ago, Dr. Waller studied C.B.T. therapists in Britain treating adults with eating disorders to see what specific techniques they used. Dr. Waller found that fewer than half did anything remotely like evidence-based C.B.T.

“About 30 percent did something like motivational work, and 25 percent did something like mindfulness,” said Dr. Waller. “You wouldn’t buy a car under those conditions.”
