Efficacy of psychosocial interventions for mental health outcomes in low-income and middle-income countries: an umbrella review

This study is registered with PROSPERO, number CRD42019135711.Findings123 primary studies from ten systematic reviews were included. The evidence on the efficacy of psychosocial interventions in adults with depression in humanitarian settings (standardised mean difference 0·87, 95% CI 0·67–1·07; highly suggestive association, GRADE: moderate) and in adults with common mental disorders (0·49, 0·36–0·62; highly suggestive association, GRADE: moderate) was supported by the most robust evidence. Highly suggestive strength of association was found for psychosocial interventions in adults with schizophrenia for functional outcomes, in adults with depression, and in adults with post-traumatic stress disorder in humanitarian settings. In children in humanitarian settings, and in children with disruptive behaviour, psychosocial interventions were supported by suggestive evidence of efficacy.InterpretationA relatively large amount of evidence suggests the benefit of psychosocial interventions on various mental health outcomes in LMICs. However, strength of associations and credibility of evidence were quite variable, depending on the target mental health condition, type of population and setting, and outcome of interest. This varied evidence should be considered in the development of clinical, policy, and implementation programmes in LMICs and should prompt further studies to improve the strength and credibility of the evidence base.FundingUniversity of Verona.
