A meta-analysis of 19 studies with 2,139 women with breast cancer and depression found that mindfulness-based interventions moderately reduce depressive symptoms compared to control conditions (effect size g = 0.48). Interventions that included home practice assignments had a much larger effect (g = 1.75) than those without (g = 0.20). Studies using concealed allocation to treatment groups found smaller effects (g = 0.11) than those not reporting it (g = 1.33). Higher sample attrition was associated with smaller effects on depression. Mindfulness-based interventions appear moderately effective as adjunct treatments for depressive symptoms in this population.
