The Longitudinal Formulation is a longitudinal CBT case formulation which addresses the crucial 5 p factors (presenting, predisposing, precipitating, perpetuating, positives). This diagram also includes a cross-sectional component (thoughts, feelings, behaviors, and physical sensations associated with a specific here-and-now situation). This style of formulation can help draw client’s attention to the links between their underlying beliefs (schemas), and their patterns of thinking and behaving in the here-and-now.
This is a 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’.
