This review assessed the efficacy of adapted psychological interventions for Black and minority ethnic (BME) groups. A conceptual typology was developed based on adaptations reported in the literature, drawing on the common factors model, competence frameworks and distinctions between types of cultural adaptations. These distinctions were used to explore the efficacy of different adaptations in improving symptoms of a range of mental health problems for minority groups. Bibliographic searches of MEDLINE, Embase, PsycINFO, HMIC, ASSIA, CENTRAL, CDSR and CINAHL spanned the period from 1965 to December 2020. Adaptations to interventions were categorised: i) treatment specific: therapist-related, ii) treatment-specific: content-related and iii) organisation-specific. Meta-analyses of RCTs found a significant effect on symptom reduction when adapted interventions were compared to non-adapted active treatments (K = 30, Hedge's g = -0.43 [95% CI: -0.61, -0.25], p < .001). Studies often incorporated multiple adaptations, limiting the exploration of the comparative effectiveness of different adaptation types, although inclusion of organisation-specific adaptations may be associated with greater benefits. Future research, practitioner training and treatment and service development pertaining to adapted care for minority groups may benefit from adopting the conceptual typology described.

本综述评估了针对黑人和少数族裔 (BME) 群体的适应性心理干预的有效性。基于文献中报道的适应，利用共同因素模型、能力框架和文化适应类型之间的区别，开发了一种概念类型学。这些区别被用来探索不同适应措施在改善少数群体一系列心理健康问题症状方面的功效。对 MEDLINE、Embase、PsycINFO、HMIC、ASSIA、CENTRAL、CDSR 和 CINAHL 的书目搜索跨越了 1965 年至 2020 年 12 月的时间段。对干预的适应分类为：i) 特定治疗：治疗师相关，ii) 特定治疗：内容- iii) 特定于组织的。K  = 30，Hedge 的g  = -0.43 [95% CI：-0.61，-0.25]，p  < .001）。研究通常包含多种适应，限制了对不同适应类型的比较有效性的探索，尽管包含特定于组织的适应可能会带来更大的好处。未来的研究、从业者培训和治疗以及与少数群体适应性护理有关的服务开发可能会受益于采用所描述的概念类型。
