Culture plays a significant role in psychotherapy practice, with cultural adaptations being implemented more commonly as globalisation and cultural awareness increase. An abundance of systematic reviews, meta-analyses and randomised controlled trials exploring culturally adapted interventions have been published across the globe. In this paper, we present the historical background to cultural adaptation by summarising and evaluating previous frameworks, as well as reviewing current evidence for such adaptations and highlighting routes for further research. Around twenty cultural adaptation frameworks have been published, covering various population demographics and intervention types, providing general guidelines for the implementation of cultural adaptations to psychosocial interventions. Nearly all the frameworks used previous literature and research to develop models on culturally adapted interventions. Some even implemented stakeholder discussions, randomised control trials, and even pilot studies. A variety of cultural adaptation factors have been outlined and discussed; however, there is no agreement on which elements work and which do not. Existing evidence indicates that culturally adapted interventions are effective, regardless of intervention type or population. While cognitive behavioural therapy (CBT) was the most common intervention in trials, there are, at present, no high-quality comprehensive meta-analyses or systematic reviews on culturally adapted CBT which include all literature on this topic. This is needed in order to provide a holistic and detailed comprehension of where current understanding lies. We conclude our paper with recommendations for researchers, trainers and commissioners.
Key learning aims
-
(1) Current theoretical frameworks guiding the development of culturally adapted frameworks will be outlined. Gaps in current literature will be highlighted.
-
(2) An overview of the current literature of culturally adapted psychotherapies, specifically CBT and its efficacy in improving outcomes for patients, will be provided.
-
(3) The need for culturally adapted CBT and comprehensive guidelines for the development of these interventions will also be discussed, with clinical implications highlighted.
