Measures are important when considering psychological therapies evidence and treatment of psychosis + distress is important

I've just come across a research brief of a paper.

CBT does not improve relapse rates in people with recently relapsed
psychosis

It's about a piece of research that was published in the British Journal
of Psychiatry last year about CBT, family interventions and psychosis.
It's a single blind randomised control trial with a reasonably good
sample size and even an effort to stratify the carers' sample.

The briefing explains that CBT doesn't affect the relapse rate nor does
family therapy. I'd like to go into the paper to see what the PANSS
scores were like (PANSS is the commonly used psychiatric measure of
psychosis). Relapse is seen as a significant failure. I think the reason
relapse is considered an important psychiatric measure is because the
cost of hospitalisation is high. CBT did not have any effect on the
other psychiatric measures used to describe schizophrenia apart from one..

CBT does reduce levels levels of depression seen in these patients in
this high quality study. They used the Beck Depression Inventory (BDI).
It seems that with individual CBT people with a diagnosis of
schizophrenia can, perhaps, be a little bit happier.

The psychiatric measures used in describing schizophrenia are
psychopathological and I feel are aligned with disorder spectrum of
mental health. The BDI scale is still pscyhopathological and psychiatric
(which is something I consider a failing) in design however it assesses
distress - the other spectrum of metal health.

The paper authors consider CBT not efficacious for the treatment of
schizophrenia.
"
Thus although individual CBT for persistent psychotic symptoms when
added to medication may confer some modest benefits in reducing
emotional distress, and should continue to be offered, it is not
efficacious in preventing further relapse among those recovering from a
recent relapse. Given the scarcity of therapist resources in this area,
this is a helpful piece of evidence for service planning and, to their
credit, it is a conclusion that the authors propose without qualification.
"

I need a piss. Where's the nearest research psychiatrist's face?

This single study shows that CBT can work for schizophrenia. It may not
address the 'cardinal' symptoms (Loren Mosher's derogarory term for the
pathological symptoms) but the evidence of this study says there is hope
for the distress of those shattered by the experience of unshared
perceptions.
