Biopsychosocial Formulation
A clinician's integrated explanatory narrative that synthesises biological, psychological, and social factors contributing to a patient's current psychiatric presentation.
Full Definition
A biopsychosocial formulation is a section of the psychiatric evaluation in which the clinician weaves together aetiological factors across three domains—biological (e.g., genetics, neurochemistry, medical comorbidities), psychological (e.g., cognitive distortions, attachment history, coping deficits), and social (e.g., housing instability, relational conflict, cultural stressors)—to explain the patient's current episode. It is a narrative interpretation rather than a factual listing of diagnoses and should be written in discursive prose. Editors must not restructure this section into bullet points, as doing so strips the clinician's interpretive reasoning. The term is hyphenated as shown and is never abbreviated.
Usage
Usage note: Always hyphenate: 'biopsychosocial'. The formulation is distinct from the diagnosis list; it is the clinician's explanatory narrative and should not be edited to resemble a checklist.
