Systematic review of mental health interventions for patients with common somatic symptoms: can research evidence from secondary care be extrapolated to primary care?
Raine, Rosalind, Haines, Andy, Sensky, Tom et al.·BMJ (Clinical research ed.)·2002
Researchers reviewed 61 studies testing mental health treatments for ME/CFS, irritable bowel syndrome, and chronic back pain. They found that cognitive behavioural therapy and behaviour therapy helped with ME/CFS and back pain, while antidepressants helped with irritable bowel syndrome. Treatments worked better when delivered in hospital settings than in GP surgeries, possibly because hospital patients had more severe illness or received closer supervision.
