The Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association (DSM-IV-TR) includes an Outline for Cultural Formulation (CF) that identifies cultural information that can be used to modify diagnosis, clinical assessment and treatment plan. This study examined the use of the CF by a Cultural Consultation Service in the psychiatric assessment of patients referred by primary care providers. The study uses conversation analysis of 12 clinical case conferences to explore the ways in which the CF influenced the interaction of a multidisciplinary group of mental health professionals in conceptualizing the implications of patients' cultural background and current context for diagnosis and treatment planning. The results suggest that the CF can be a useful tool for interdisciplinary collaboration and knowledge transfer by providing a framework to systematically introduce different disciplinary perspectives and levels of description that transcend the narrow frame of disorder-centred psychiatric diagnosis, assessment and care.

Culture is an essential variable of diagnosis and treatment. A cultural perspective draws attention to the social context within which symptoms arise, are given meaning, and are managed. Ethno-cultural work on illness narratives suggests that most people can provide culturally-based explanations for their symptoms. While these explanations are inconsistent with biomedical theory, they relieve patient distress by allowing the patient to create meaning for symptoms. Exploring the characteristics, context, and antecedents of the symptoms enables the patient to convey them to the clinician who may have a divergent explanation of sickness. This case study uses the Outline for Cultural Formulation of the DSM-IV created for clinicians to elicit a narrative account of the illness experience from the patient. Our study examines how the patient, a Laotian used social indignation ("Kwam khem keuang") as an explanatory model for his ailment. He was diagnosed with post-traumatic stress disorder after having undergone a traumatic amputation. In the process of explaining his illness through a cultural idiom, the patient was able to reveal both personal and collective meaning of repressed anger and frustration, expressing them in a context that was acceptable to him. This cultural idiom allowed the patient to reflect upon the structure of the health care system and the specific context in which symptoms and their possible origins are recounted and explored. It also clarified to the treating clinicians some categories of experience and causal explanations that did not fit easily with western biomedical and psychiatric understanding. The case study illustrates how a cultural approach to illness from the patient's perspective offers a reflexive stance on the clinician-patient interaction that allows for better patient care.
