Patient and clinician communication practices during the DSM-5 cultural formulation interview field trial

摘要

Cultural psychiatrists and medical anthropologists have collaborated to help clinicians screen for culture-related issues in patient explanatory models of illness and to enhance the clinical processes of engagement, diagnosis, and treatment planning. This effort prioritises patient perspectives on suffering and healing to counter the trend of symptom-based interviews which assume biologically determined models of mental disorders. The 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes the Cultural Formulation Interview (CFI), a semi-structured questionnaire for eliciting patient explanatory models. This paper analyses specific linguistic meanings and practices that could account for patient perceptions of improved rapport with clinicians, clinician perceptions of improving information gathering, and cultural models of health and illness during the DSM-5 field trial piloting the CFI. Twenty-seven audiotapes were analysed through the Roter Interaction Analysis System (RIAS), a standardised method for examining medical interviews based on ethnographic studies of small-group communication. After an introduction with procedural and reassurance statements to orient communication, the CFI's open-ended questions elicited patients' opinions on interpersonal, environmental, and biomedical information. Clinicians made facilitation and activation statements for patients to speak more and informed patients about what to expect. Patients constructed cultural models of illness that weaved interpersonal, environmental, and biomedical information. Clinicians and patients made rapport-building statements to each other. A RIAS-derived patient-centred score indicates that CFI sessions addressed patient concerns. Our work offers a way to analyse the discursive construction of culture in health settings and patient-centredness through detailed examinations of linguistic meanings and practices.
