Cultural Adaptations to the Assessment and Treatment of Trauma Experiences Among Racial and Ethnic Minority Groups: A...

A higher prevalence of post-traumatic stress disorder (PTSD) exists among racial and ethnic minority groups who experience trauma; however, little is known about cultural adaptations of trauma assessments and interventions, or whether those adaptations meet cultural needs. This systematic review examined the effectiveness and experiences of culturally adapted trauma assessments and interventions for adults from racial and ethnic minority groups. Empirical studies investigating culturally adapted trauma assessment and/or interventions targeting adults from racial and ethnic minority groups were searched for in MEDLINE, PsycINFO, Embase, Scopus, CINAHL, Cochrane Central Register of Controlled Trials, Web of Science, from inception to May 2022. A total of 21 articles were included, and 8 common themes of adaptations were identified: socio-cultural integrations, collaboration, psychoeducation, language, cultural matching, addressing stigma, training for providers, and practical considerations. Random effects meta-analyses on intervention effects showed that culturally adapted interventions were more effective in reducing PTSD symptoms (7 randomized controlled trials [RCTs], n = 213, Standardized Mean Difference -0.67, 95% CI [-1.06, -0.25], I² = 39%) and in ameliorating anxiety symptoms (5 RCTs, n = 168, SMD -1.92, 95% CI [-3.18, -0.67], I² = 89%) when compared with non-adapted interventions at immediate post-intervention. No statistical difference in effects was found on depression, nor on PTSD or anxiety sustained beyond the post-intervention time-point. Thematic synthesis on participants' experiences showed that adapted interventions had positive influences on attitudes toward mental health and engagement with services. Future research should employ large-scale trial methods to test adapted trauma interventions over longer follow-up periods as well as to explore the subjective experiences of users of adapted interventions.
