Cognitive Behavioral Model of Anorexia Nervosa: PDF Worksheet, Tools and Exercises

In sessions with patients presenting anorexia nervosa, explaining the cognitive-behavioral maintenance model verbally tends to fall flat. The patient nods, yet the connection between over-evaluation of shape and weight and the starvation-driven rigidity that locks the disorder in place rarely clicks without a visual scaffold. This fiche PDF is built for exactly that moment: a structured psychoeducation support the clinician uses in session to make the loop visible, nameable, and discussable.

Why the CBT model of anorexia resists oral explanation

The core mechanism Fairburn (2008) describes is counterintuitive: the strategies the patient experiences as protective (restriction, rigid rules, hidden exercise) actively fuel the neurological and psychological conditions that make recovery feel impossible. Said verbally, this risks being heard as one more criticism of their coping. The concept of the starved brain is particularly hard to transmit without a diagram. Patients consistently attribute cognitive narrowing, obsessive food thoughts, affective flatness, and all-or-nothing thinking to their personality or a permanent defect, not to the predictable physiological consequences of undernutrition as documented in Keys (1950).

The over-evaluation itself is equally slippery at the oral level. Without a visual circuit showing the chain of consequences downstream, patients struggle to see the link between a self-worth fused to weight and shape and the tightening of behavioral control. What looks from the outside like a cluster of symptoms reads to the patient as separate, poorly managed behaviors, not as expressions of a single self-maintaining loop.

Therapeutic ambivalence compounds this further. A patient can verbally agree the loop exists while every part of their functioning works to protect it. The motivational discrepancy work that often follows is only possible once the model is genuinely internalized, not simply recited back.

What the fiche contains: a visual scaffold for the maintenance cycle

The fiche is organized around six panels that build the model progressively, grounded in Fairburn (2008) and Treasure (2015).

The opening panel renders the self-fuelling loop as a visual circuit with five labelled nodes: over-evaluation, rigid control, low weight, starved brain, and fear and rigidity, with arrows closing the circle. Seeing it diagrammed is, for many patients, the first moment the trap becomes legible: "Control feels like the one working strategy. It is actually feeding the problem."

The second panel distinguishes the two faces of the cycle side by side: the restricting pattern (strict rules, food group elimination, hidden exercise, fillers like gum and coffee) and the binge/purge pattern (restriction setting up the break, then undoing behaviors and the "reset trap" of skipping tomorrow). This layout helps you and the patient quickly identify which face is currently dominant, a clinically important distinction that patients often resist articulating without a concrete prompt. It connects directly to the separate work available in the CBT model of bulimia nervosa for patients who oscillate between both patterns.

A third panel offers a useful inner test: "If my body and my eating became a non-issue tomorrow, what would still matter to me?" A very short answer signals the degree to which the over-evaluation has contracted other life domains. You can use this prompt directly in session to open values clarification work.

The starvation syndrome panel is often the most therapeutically potent element of the fiche. It maps predictable consequences across four domains: mental (food obsession, narrowed focus, decisional paralysis), emotional (irritability, flatness, anxiety spikes around meals), social (avoidance, loss of interest in closeness), and physical (cold intolerance, fatigue, hair thinning, amenorrhea). Presenting these explicitly as undernutrition effects, not personality traits, directly addresses the self-blame and the low self-esteem dynamics that reinforce the disorder. It also creates an opening for discussing perfectionism co-occurrence, common in this presentation.

The closing section includes a "To discuss in session" prompt list and a four-point "Remember" summary (It's a loop / Not personality / Eating first / Both at once), giving you ready-made debrief anchors.

> Key takeaway: This fiche is a visual support that facilitates the explanation of the CBT model of anorexia nervosa in session. The clinician uses it as a shared reference during psychoeducation; it is not a self-administered questionnaire, but a tool for building a common vocabulary and leaving the patient with a portable, concrete map of the loop.

When and how to introduce the fiche in session

This tool fits best in the early psychoeducation phase, once the alliance is solid enough to name the disorder directly and the patient has some capacity for reflective engagement. For patients in acute medical compromise, the starvation syndrome panel serves as a lower-threat entry point: you are not yet asking them to challenge over-evaluation, only to recognize a documented list of physiological consequences visible in the anorexia signs checklist.

A useful introduction: "I'd like to show you a diagram of how this tends to keep itself going. We don't need to agree with all of it today. I just want us to have the same map." Framing it as a shared reference, not a verdict, lowers defensive reactivity. For patients who also meet criteria for BDD-adjacent body image distortion, the body dysmorphic disorder resource can complement the over-evaluation panel.

Debrief by asking which node of the loop feels most recognizable and which one they find least convincing. When the inner test prompt surfaces a very thin answer, that is your signal to move toward identifying what genuinely matters once weight restoration creates the cognitive space to do so.

The "Both at once" point in the "Remember" summary matters clinically. Naming ambivalence explicitly, rather than treating it as resistance, often preserves the alliance through the most destabilizing phases of refeeding. The fiche does not close the loop for the patient; it makes the loop visible enough, and consensual enough, to begin the work.
