Abstract

BACKGROUND: Most survivors of mass violence live in low- and middle-income countries (LMICs). We conducted a meta-analysis of randomized controlled psychotherapy trials for adult posttraumatic stress disorder (PTSD) and/or depression in LMICs. METHODS: We included 18 clinical trials (3,058 participants), in which 25 and 18 treatment arms measured symptoms of PTSD and depression, respectively. RESULTS: Active treatments for PTSD yielded a large aggregated pre-post effect size (g = 1.29; 95% CI = [0.99; 1.59]) and a small to medium effect size at posttreatment when compared to control conditions (g = 0.39; 95% CI = [0.24; 0.55]). Effect sizes were similar for pretreatment versus follow-up (g = 1.75; 95% CI = [1.17; 2.32]) and in comparison to waitlist at follow-up (g = 0.93; 95% CI = [0.56; 1.31]). Active treatments for depression produced large pre-post (g = 1.28; 95% CI = [0.96; 1.61]) and controlled effect sizes (posttreatment, comparison to control conditions, g = 0.86; 95% CI = [0.54; 1.18]). CONCLUSIONS: Our findings suggest that psychological interventions can effectively reduce symptoms of PTSD and depression in LMICs. Future research needs to focus on cost-effective interventions that are likely to be disseminated to the large numbers of war survivors in LMICs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
