A case formulation (case conceptualisation) can be thought of as any way of helping a client to understand what their difficulties are, where they originated, and what keeps them going. CBT case formulations often have 5 ingredients:
- Presenting problem(s)
- Predisposing factors which made the individual vulnerable to the problem
- Precipitating factors which triggered the problem
- Perpetuating factors such as mechanisms which keep a problem going or unintended consequences of an attempt to cope with the problem
- Protective factors
This Friendly Formulation diagram presents all of the these 5 p’s in an accessible way, framed by the question “How did the problem develop?”.
This is a Psychology Tools case formulation (case conceptualization) diagram. Put simply, case formulation is one method of a client and therapist coming to shared understanding of a difficulty. The formulation contextualizes the difficulty, making its origin and maintenance understandable. Case formulations are best completed collaboratively, with clients positioned as the ‘experts in themselves’.
