Introduction: Mindfulness-based interventions (MBIs) are effective in improving mental health outcomes, including depression, anxiety, and post-traumatic stress disorder (PTSD). However, research on how MBIs have been tailored for racial and ethnic minoritized communities is limited. To address this gap, this scoping review utilizes the Ecological Validity Framework to systematically explore cultural adaptations in MBIs for communities of color. Concurrently, this review examines the effectiveness of culturally adapted MBIs. Methods: Following PRISMA guidelines, the authors conducted a search on MEDLINE, PsycINFO, and Embase databases from 2010 to 2023. Inclusion criteria required studies to be published in English, accessible in full-text, and peer-reviewed, focusing primarily on communities of color or diverse non-White populations (comprising 75% or more of the sample). Exclusion criteria were studies primarily centered on behavioral interventions other than MBIs, studies lacking primary outcomes, and studies not explicitly addressing cultural adaptations. Results: Search results identified 371 publications, 13 of which met the inclusion criteria. The most frequently reported cultural adaptations were surface-level adaptations, which can enhance the relevance of MBIs by modifying the language, content, format, or intervention delivery. MBIs with surface-level adaptations reported significant improvements in mental health outcomes, including depression, anxiety, and stress levels. Conclusion: Findings from this review indicate that culturally adapted MBIs for communities of color could potentially make them more relevant and acceptable. Surface-level and deep structure adaptations are both necessary to ensure MBIs are responsive, relevant, and sustainable across diverse contexts and populations.
