What is the role of formulation in contemporary mental health practice?

ObjectiveThis paper reviews the role of formulation in contemporary mental health practice. It traces the historical and conceptual development of formulation to its current use across multiple therapeutic models. Formulation is presented as an essential integrative clinical skill that supports patient-centred care, multidisciplinary collaboration, and real-time decision-making. The paper contrasts formulation with diagnosis, highlighting its individualised explanatory power, epistemological diversity, and capacity to organise clinical uncertainty. It also examines the role of the hypothesis-driven interview and relational awareness in generating meaningful formulations. ConclusionsFormulation is a core clinical competency. Although less easily operationalised than making a diagnosis and vulnerable to critiques of subjectivity, its validity is grounded in disciplined observation, iterative reasoning, and the development of a shared understanding with the patient. Formulation enhances therapeutic alliance and underscores defensible decision-making. The re-emergence of formulation as an assessable competency in psychiatric training represents an opportunity to reinforce formulation as central to our professional identity.
