Hutton P and Taylor PJ. Cognitive behavioural therapy for psychosis prevention: a systematic review and meta-analysis. Psychological Medicine (2013): 1-20
At every time point, the relative risk of transition was reduced by more than 50% for those receiving CBT. (Hutton & Taylor 2013)
First, what is the design of the McGorry et al study? Well...participants were randomly assigned to the following groups:
not -in fact - part of a randomised trial (but self-selecting controls!)
McGorry et al then have no CBT group (as such) and no randomised control group (as such)...
So, its difficult to see how the studies by Bechdolf et al and McGorry et al could be described as assessing the impact of CBT per se
and when they are r
emoved them from the equation ...the effect is non-existent
As mentioned, I have covered the Stafford et al meta analysis and some of the studies and issues in my other post. Nevertheless, I would conclude by reiterating:
a) the extremely low transition rates (<10%) of Ultra High Risk individuals
b) CBT shows no evidence of preventing transition - indeed, no single study shows a significant and reliable effect; and finally,
c) even if CBT did prevent transition to psychosis ...How would it actually be preventing psychosis? The whole approach is bereft of any theoretical ideas on this notion - one thing is sure - it is NOT via the reduction of symptoms - as both meta analyses definitely show that symptoms do not change from before to after CBT
