What is it about?

'Formulation' is a major way that mental health professionals such as psychologists and psychiatrists explain individuals mental health challenges. However, there appears to be a lot of variation in how professionals formulate. This introduces a clear framework that maps nine key ways that approaches to formulation can vary. The aim is to help professionals better describe, compare, and reflect on how they understand clients’ difficulties and guide care.

Why is it important?

This article is important because it tackles a quiet but widespread problem in mental health work: when clinicians say “formulation,” they often mean different things - often without realising it. This paper provides clear language and structure for understanding how and why formulations differ, without arguing that one way is “right.” By setting out nine key dimensions where practice varies, it helps clinicians reflect on their own habits, talk more clearly with colleagues, and teach formulation more explicitly. This matters for training, teamwork, and client care, because misunderstandings about formulation can lead to confusion, disagreement, or unhelpful rigidity. It should also be helpful for researchers developing frameworks to guide formulation. In short, the article helps the field stop talking past itself and start thinking more clearly about a core clinical skill that often goes underexamined.

Perspectives

Some of my work is liable to be criticized for being overly abstract or philosophical - somewhat at a distance from day to day clinical decision making (I understand this concern but obviously disagree!). Still, I am excited about this paper as it is so clearly practical in nature. Formulation is an everyday task for many mental health professionals, and I hope this paper demonstrates how theoretical ideas can help improve everyday professional discourse and understanding. P.S. - during review of this paper some hypothetical examples were removed, if anyone wants to use them, for example for teaching purposes, them please feel free to contact me.
