  1. Note: aAll effect sizes reported in the studies reviewed were computed so that positive values indicate greater benefit for culturally adapted treatment over their comparison group; bIn these comparisons, culturally adapted treatments are compared to heterogeneous controls conditions that include other un-adapted treatment, usual care, waitlist conditions, and attention control; cIn these comparisons, specific culturally adapted psychotherapies are compared to the same un-adapted psychotherapy; deffect sizes for all studies included in this meta-analysis; eeffect size for studies that only compared culturally adapted interventions to an ‘alternative intervention.’ *Primary measures; **All measures.
