Cognitive-behavioural therapy (CBT) is a well-recognised psychotherapeutic intervention for the treatment of a number of psychiatric conditions such as depression, anxiety, eating disorders and obsessive-compulsive disorder.1 Furthermore, CBT techniques have proven to be efficacious in targeting specific conditions such as chronic delusions and hallucinations in schizophrenia. Lord Layard examined the need for psychological treatments in the UK and speculated that there will be a demand to train 5000 more psychological therapists by 2013, mostly in CBT.
