Ooh! Not what you were looking for - but there was a study about how therapists are pretty clueless about when their patients are getting worse. They just don't see it. They don't understand why/when people are being "social" and saying, "I'm fine! You're doing a great job!" but actually falling apart.

The article was about how using tests, particularly computerized surveys, to get an ongoing reading of how the patient is functioning - because people are more likely to answer honestly when the computer asks how depressed they are, rather than a therapist asking face-to-face.

The study showed that most therapists *think* they're awesome at this, and don't see the need for testing - but outcomes are much improved (less dropouts, less falling out, and less suicide!) when they actually use the tests.

That's all from memory of the article, but here's the article if you want to check it out:
