Marriage therapy doesn't work

The NY Times reports:

Each year, hundreds of thousands of couples go into counseling in an effort to save their troubled relationships.

But does marital therapy work? Not nearly as well as it should, researchers say. Two years after ending counseling, studies find, 25 percent of couples are worse off than they were when they started, and after four years, up to 38 percent are divorced.

... experts say many therapists lack the skills to work with couples who are in serious trouble.

I guess that the therapists blame all the failures on the other therapists who supposedly lack skills.

I wonder what percentage of couples are actually damaged by the therapy. Some couples see a therapist, get bad advice, act on the bad advice, and end up much worse off.
