Evidence that cognitive therapy is of no value in schizophrenia

Jun 26, 2009

Research co-led by an academic at the University of Hertfordshire, concludes that Cognitive Behavioural Therapy (CBT) is of no value in schizophrenia and has limited effect on depression.

Professor Keith Laws, at the University's School of Psychology, is one of the lead authors on a paper entitled: Cognitive behavioural therapy for major psychiatric disorder: does it really work? A meta-analytical review of well-controlled trials, which has just been published online in the journal Psychological Medicine. The paper reviews the use of CBT in , bipolar disorder and .

The results of the review suggest that not only is CBT ineffective in treating schizophrenia and in preventing relapse, it is also ineffective in preventing relapses in bipolar disorder.

The review also suggests that CBT has only a weak effect in treating depression, but it has a greater effect in preventing relapses in this disorder.

The authors focused particularly on methodologically rigorous trials that compared CBT to a ‘psychological placebo' and also investigated the impact of ‘blinding', i.e. whether or not the people who assessed the patients knew if they were receiving active treatment or not. Both factors are considered essential before a drug treatment is approved for use in .

The authors noted that not a single trial employing both blinding and psychological has found CBT to be effective in schizophrenia and surprisingly few well-controlled studies of CBT in depression.

"The results of this review are important because in March NICE re-approved CBT for use in all people with schizophrenia. The Government is also investing millions of pounds to provide CBT for depression and in 250 dedicated therapy centres across England," said Professor Laws. "Yet the evidence here is that the effectiveness of this form of therapy may be less than previously thought, to the point of being non-existent in schizophrenia."

The other authors of the paper are Professor Peter McKenna, Benito Menni Complex Assistencial en Salut Mental, Barcelona and Dr Damian Lynch, University of Glasgow.

Having been in therapy for depression for almost 7 years, it's only obvious that the effectiveness of CBT is minimal. I mean, 7 years of treatment! I think these findings reflect the relative lack of skill amongst therapists. Mental pathology is so difficult to understand, only the really bright and talented therapists have a significant affect in a short period of time. Out of the 6 or 7 so therapists I've sought treatment from, only 1 was really good and 1 was excellent, having come from Harvard.

I know quite a few schizophrenics. Having been in inpatient care for 2 years, you run into quite a few of them. CBT does almost nothing except extend the time between relapses and episodes. My co-resident who suffered from severe auditory hallucinations was at the whim of his symptoms, and CBT on virtually a daily basis merely increased his quality of life by a small margin. He eventually couldn't take it anymore and committed suicide. CBT just isn't a powerful treatment.
