OBJECTIVE: A growing literature supports mindfulness and acceptance-based interventions (MABIs) for depression prevention and treatment with individuals from dominant cultural groups, and MABIs have been theorized to be well suited to resonate with individuals from nondominant groups. The aim of the current meta-analysis was to determine whether this promise is realized in practice by evaluating the efficacy of MABIs for depression symptoms in Black Americans. METHOD: Thirty studies with an adequate proportion (>20%) of Black Americans were identified using previous reviews and electronic databases, yielding a total of 1,703 participants with an average proportion of 70% Black Americans. Data on moderators (i.e., geographic location, study design, and intervention protocol) and outcomes were extracted and analyzed using metaregression. RESULTS: Results indicated a moderate effect of MABIs on symptom outcomes in the full sample g = 0.48. Effect sizes were similar in study subsets comprising majority (>50%; k = 19) g = 0.39, and predominantly (>90%; k = 10) g = 0.35, Black participants, with no significant moderating effect of racial composition. Effects were moderated by both sample and intervention level characteristics. CONCLUSIONS: The current findings support the conclusion that MABIs are efficacious to varying degrees for Black Americans; with stronger support for use in adult samples than youth samples. These results are promising, and further support efforts to expand research on evidence-based treatments (EBTs) to meet the specific mental health needs of Black Americans.
