2. The full text requires an account, the abstract says this...

"...longitudinal data collected from 278 patients over a 6-month period following admission to an outpatient dual diagnosis treatment program..."

I imagine using patients from dual diagnosis treatment program introduces some bias toward patients who were cooperative help-seekers. I have no real idea how that would effect the analysis, if any.

Misdiagnosis is a continuing problem. My experience is a psychiatric diagnosis is rather more hypothesis than what is experienced in with "physical" health problems.

It's also my experience that psychotherapy is often the same regardless of dx. So in a practical sense differential diagnosis isn't something that's much worried about, until a patient doesn't move toward resolution.
