There is no single "correct" case formulation template in CBT — four different models are in widespread clinical use, each with different strengths. The Beck 7-component model is the most thorough; the Padesky 5-aspect model is the most practical for in-session work; the 5-P model is the most common in UK NHS settings; Persons’ cognitive-behavioral formulation is the most flexible. This guide compares them side by side and explains when to use which.
Beck 7-component model
The classic comprehensive model from Judith Beck. Seven components: presenting problems, precipitating factors, predisposing factors, core beliefs, intermediate beliefs, automatic thoughts, maintaining factors.
Strengths: Most thorough. Captures developmental history. Schema-level work is built in.
Limitations: Time-intensive to construct. Can be cumbersome in brief therapy.
Best for: Long-term CBT, schema-focused work, complex presentations, training contexts where thorough formulation is valued for skill development.
Padesky 5-aspect model (hot cross bun)
Christine Padesky's model — five interlocking aspects: thoughts, feelings, physical sensations, behaviors, environment. Often diagrammed as a "hot cross bun" with the four internal aspects in quadrants and environment as the surrounding context.
Strengths: Highly client-friendly. Easy to draw on a whiteboard. Captures the maintenance cycle visually. Excellent for psychoeducation.
Limitations: Does not directly capture developmental history or schema-level work. Best used in conjunction with deeper formulation work.
Best for: Brief CBT, single-problem focus, client-facing psychoeducation, in-session work where the formulation needs to be visible and editable in real time.
5-P model
The 5-P model — Presenting, Predisposing, Precipitating, Perpetuating, Protective factors. Originally from Spielman's work on insomnia, now widely used across the UK NHS for general formulation.
Strengths: Includes protective factors (strengths, support systems) which the Beck and Padesky models can underweight. Clear conceptual structure.
Limitations: Less guidance on cognitive content. Strong on what maintains the problem, weaker on the specific cognitive architecture.
Best for: NHS contexts, generalist mental health, presentations where protective factors matter clinically, sleep disorder work specifically.
Persons’ cognitive-behavioral formulation
Jacqueline Persons’ hypothesis-driven model. Three levels: problem list, mechanism (cognitive and behavioral), origin. Treatment plan flows directly from the mechanism hypothesis.
Strengths: Most explicit linkage between formulation and treatment plan. Hypothesis-driven structure encourages iterative refinement. Highly flexible.
Limitations: Requires more clinical judgment than the more structured models. Less prescriptive.
Best for: Experienced clinicians, complex multi-problem presentations, contexts where the treatment plan needs to be tightly linked to the formulation.
How to choose between them
The four models are not in competition. Most experienced clinicians use them in combination — Padesky for in-session work and client psychoeducation, Beck or Persons for the full written formulation, 5-P for structured services or insomnia work.
Practical recommendation for early-career clinicians: Learn Beck thoroughly first (it is the most comprehensive and the foundation for the others), then add Padesky for client-facing work, then explore 5-P and Persons as your practice evolves.
For practice management: Whichever model you use, having structured templates in your documentation tool reduces the friction of building thorough formulations. CBT Assistant Pro includes all four model templates with the relevant fields pre-structured; clinicians can select the model per client or per service.
Frequently asked questions
Which case formulation model is best?
There is no single best model. All four are evidence-based and produce good outcomes when used skillfully. Selection depends on context: training environment, service setting, client preference, and the specific clinical question being formulated.
Can I combine multiple formulation models for one client?
Yes, and most experienced clinicians do. The Padesky 5-aspect is often used in session for psychoeducation while a Beck or Persons formulation captures the full written conceptualization for case planning.
How long should a written case formulation be?
Most professional formulations run 1-3 pages. Brevity matters; the formulation should be readable in 5 minutes and capture the essential clinical hypothesis. Length beyond 3 pages often signals unfocused conceptualization.
Are formulation templates compatible with insurance documentation requirements?
Yes. All four models contain the elements insurers look for: presenting problem, contributing factors, treatment plan linkage. Structured templates can simplify generating insurance-compliant treatment plans from the formulation.
Do I need to share the formulation with the client?
Strongly recommended. Collaborative formulation produces better engagement and outcomes than therapist-only formulation. The Padesky 5-aspect model is specifically designed for collaborative in-session construction.
