Cognitive behavioural therapy 'can reduce depression'

Cognitive behavioural therapy (CBT) can reduce symptoms of depression in people who fail to respond to drug treatment, says a study in the Lancet.

CBT, a type of psychotherapy, was found to benefit nearly half of the 234 patients who received it combined with normal care from their GP. Up to two-thirds of people with depression do not respond to anti-depressants. Patients should have access to a range of treatments, the charity Mind said.

CBT is a form of talking psychotherapy to help people with depression change the way they think to improve how they feel and alter their behaviour.

The study followed 469 patients with treatment-resistant depression picked from GP practices in Bristol, Exeter and Glasgow over 12 months. One group of patients continued with their usual care from their GP, which could include anti-depressant medication, while the second group was also treated with CBT.

After six months, researchers found 46% of those who had received CBT reported at least a 50% reduction in their symptoms. This compared with 22% experiencing the same reduction in the other group.

The study concluded CBT was effective in reducing symptoms and improving patients' quality of life. The improvements had been maintained for a period of 12 months, it added.

Other options

Dr Nicola Wiles, from the Centre for Mental Health, Addiction and Suicide Research at the University of Bristol, said: "While the addition of CBT was effective for patients who had not responded to anti-depressants, not everyone who received CBT got better. These patients had severe and chronic depression so it is unlikely that one treatment would be effective for everyone." "We need to invest in other research to find alternative treatments for patients whose symptoms have not responded to treatment with anti-depressants." The patients who did benefit from cognitive behavioural therapy spent one hour a week with a clinical psychologist learning skills to help change the way they think.

Chris Williams, professor of psychosocial psychiatry at the University of Glasgow, and part of the research team, said: "The research used a CBT intervention alongside treatment with anti-depressants. It confirms how these approaches - the psychological and physical - can complement each other.  "It was also encouraging because we found the approach worked to good effect across a wide range of people of different ages and living in a variety of settings."

Paul Farmer, chief executive at the mental health charity Mind, said there was no "one size fits all" treatment for people with mental health problems. "We welcome this research because it recognises that patients should have the right to a wide range of treatment options based on individual needs," he said. "Initiatives such as the Improving Access to Psychological Therapies (IAPT) programme has helped to ensure that more treatment options are available for conditions such as depression, however, we know that there still is a huge difference between what treatment people want and what they actually get."
