title: Cognitive-behavioural therapy for depression in people with a somatic disease: meta-analysis of randomised controlled trials.
abstract: BACKGROUND
  Meta-analyses on psychological treatment for depression in individuals with a somatic disease are limited to specific underlying somatic diseases, thereby neglecting the generalisability of the interventions.
  
  
  OBJECTIVE
  To examine the effectiveness of cognitive-behavioural therapy (CBT) for depression in people with a diversity of somatic diseases.
  
  
  METHODS
  Meta-analysis of randomised controlled trials evaluating CBT for depression in people with a somatic disease. Severity of depressive symptoms was pooled using the standardised mean difference (SMD).
  
  
  RESULTS
  Twenty-nine papers met inclusion criteria. Cognitive-behavioural therapy was superior to control conditions with larger effects in studies restricted to participants with depressive disorder (SMD = -0.83, 95% CI -1.36 to -0.31, P<0.001) than in studies of participants with depressive symptoms (SMD = -0.16, 95% CI -0.27 to -0.06, P = 0.001). Subgroup analyses showed that CBT was not superior to other psychotherapies.
  
  
  CONCLUSIONS
  Cognitive-behavioural therapy significantly reduces depressive symptoms in people with a somatic disease, especially in those who meet the criteria for a depressive disorder.
