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.
To examine the effectiveness of cognitive–behavioural therapy (CBT) for depression in people with a diversity of somatic diseases.
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).
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.
Cognitive–behavioural therapy significantly reduces depressive symptoms in people with a somatic disease, especially in those who meet the criteria for a depressive disorder.
