The Cultural Formulation Interview since DSM-5: Prospects for training, research, and clinical practice.

While social science research has demonstrated the importance of culture in shaping psychiatric illness, clinical methods for assessing the cultural dimensions of illness have not been adopted as part of routine care. Reasons for limited integration include the impression that attention to culture requires specialized skills, is only relevant to a subset of patients from unfamiliar backgrounds, and takes too much time to be useful. The DSM-5 Cultural Formulation Interview (CFI), published in 2013, was developed to provide a simplified approach to collecting information needed for cultural assessment. It offers a 16-question interview protocol that has been field tested at sites around the world. However, little is known about how CFI implementation has affected training, health services, and clinical outcomes. This article offers a comprehensive narrative review that synthesizes peer-reviewed, published studies on CFI use. A total of 25 studies were identified, with sample sizes ranging from 1 to 460 participants. In all pilot CFI studies 960 unique subjects were enrolled, and in final CFI studies 739 were enrolled. Studies focused on how the CFI affects clinical practice; explored the CFI through research paradigms in medical communication, implementation science, and family psychiatry; and examined clinician training. In most studies, patients and clinicians reported that using the CFI improved clinical rapport. This evidence base offers an opportunity to consider implications for training, research, and clinical practice and to identify crucial areas for further research.
