The Formulation, Restated
A composite 22-year-old barista has bulimia nervosa. She follows strict dietary rules, eating almost nothing until evening. By evening she is hungry, a small lapse such as a pastry at work breaks a rule, and she concludes the day is ruined; a binge follows, then self-induced vomiting, then renewed restriction the next morning. Beneath the cycle is a way of judging herself: her sense of worth depends largely on her shape and weight. She binges and vomits about three evenings a week. She is medically stable on screening, with normal electrolytes at her last visit. Her binges are not set off by strong emotions; she describes them as following hunger and the feeling of having "already blown it." She began dieting at 17 after a coach commented on her weight, and the binge cycle started about two years later. She lives with a roommate, works early shifts that make regular breakfast difficult and has told no one except her primary care provider. She wants treatment because the vomiting frightens her and because she is tired of planning her evenings around it.
The Criterion
The formulation identifies two elements that sustain everything else: dietary restraint, which produces hunger and rule-breaking, and the overvaluation of shape and weight, which drives the restraint. A modality suits this patient to the extent that it acts directly on restraint and overvaluation, since those two elements keep the cycle turning. Each candidate below is tested against that criterion, and against the trial evidence in adults with bulimia nervosa, and the paper states what each would leave unaddressed.
Enhanced Cognitive Behavioral Therapy
Target: both elements directly. Enhanced CBT replaces rigid dieting with regular eating of meals and snacks, which removes the hunger and the rules that trigger binges, and it addresses overvaluation of shape and weight through work on body checking, avoidance and self-evaluation (Fairburn, 2008). Evidence: in a two-site trial of the transdiagnostic form of this treatment, patients with bulimia nervosa and related eating disorders showed substantial improvement that was largely maintained at 60-week follow-up (Fairburn et al., 2009). Left unaddressed: little, for this formulation, although it does not specifically target interpersonal problems if they emerge. Verdict: first choice.
Interpersonal Psychotherapy
Target: interpersonal problems thought to maintain the eating disorder, addressing the binge cycle only indirectly. Evidence: in a multicenter trial comparing cognitive behavioral therapy and interpersonal psychotherapy for bulimia nervosa, cognitive behavioral therapy produced faster improvement, while outcomes for the two were similar at one-year follow-up (Agras et al., 2000). Left unaddressed: restraint and overvaluation are not targeted directly. Verdict: effective and a reasonable alternative, but slower and less direct for this formulation.
Dialectical Behavior Therapy
Target: emotion regulation. It suits binges driven by intense emotion, where eating serves to manage distress. Her binges follow hunger and broken rules rather than emotional crises. Left unaddressed: restraint and overvaluation. Verdict: a poor fit for this formulation, though it would be reconsidered if emotional triggers emerged.
Family-Based Treatment
Target: the family's role in restoring normal eating. Its evidence is in adolescents living at home. She is 22 and lives independently. Verdict: not indicated, although involving her roommate or a supportive friend in a session could still help later.
What Enhanced CBT Would Look Like for Her
Treatment would run about 20 sessions over 20 weeks, twice weekly at first. The early sessions would establish real-time self-monitoring of eating, binges and vomiting, and a pattern of three meals and two or three snacks a day at planned times, which directly undermines the restraint that sets up her evening binges. She would be weighed weekly in session, which addresses her fear of weight gain with data rather than avoidance. Middle sessions would target the overvaluation of shape and weight: identifying body checking, such as pinching her stomach in the mirror before work, and avoidance, such as refusing to wear fitted clothes, and building other domains of self-evaluation, such as her photography and friendships. Later sessions would address dietary rules one by one and prepare a plan for handling setbacks. Each element maps to one part of her formulation.
Guided Self-Help
National guidance lists a bulimia-focused guided self-help program as the first step for many adults with bulimia nervosa, with individual eating disorder-focused CBT offered if self-help is unacceptable, contraindicated or ineffective (National Institute for Health and Care Excellence, 2017). The case detail that settles it: she worked through a self-help book on her own last year and abandoned it after three weeks, saying she "needed someone to answer to." Guided self-help adds a clinician's support to a self-help program, but after a failed attempt at self-directed work and with symptoms three times a week, moving to individual enhanced CBT is reasonable, and the paper records that reasoning rather than skipping the guidance.
Medication and Medical Monitoring
Medication is a separate question outside this paper. Medical monitoring is a parallel responsibility: repeated vomiting can cause low potassium and other electrolyte disturbances, so her electrolytes should be checked periodically during treatment regardless of the therapy chosen.
When to Change Course
Early response predicts outcome in this treatment, so the plan includes a checkpoint. If binges and vomiting have not fallen by at least half by week 6, the formulation will be revisited to see whether something was missed, such as emotional triggers that would favor adding elements from dialectical behavior therapy, or interpersonal problems that would favor a switch to interpersonal psychotherapy. A referral for medication review would also be considered at that point. Any sign of medical instability, such as abnormal electrolytes, fainting or rapid weight loss, would prompt medical assessment and could require a higher level of care.
Conclusion
Enhanced cognitive behavioral therapy is chosen because it acts directly on both elements that sustain her binge cycle and has strong trial evidence in adults with bulimia nervosa. Progress will be measured by the weekly frequency of binges and vomiting, recorded in her own monitoring records, and by a validated measure of eating disorder symptoms at the start and every four weeks. The early-shift schedule will be addressed in the first sessions, since a meal plan she cannot follow at work would undermine the treatment's first and most important step.

How this MN661 Unit 5 example is structured
The criterion is stated before any modality is named, which is the paper's central discipline: once the formulation has said what sustains the problem, choosing becomes a matter of fit rather than preference. Every candidate then answers three questions, which element of the formulation it targets, what trial evidence supports it in adults with bulimia nervosa, and what it would leave unaddressed. Evidence is dated and attributed in the sentence, never gathered into a closing paragraph. Rejected options are treated fairly, and interpersonal psychotherapy is described as effective, merely slower and less direct for this formulation. Guided self-help gets its own paragraph because guidance lists it first, and the case detail that settles it, a self-help book she abandoned last year, is quoted. Medication is mentioned once, as a separate question outside this paper, and medical monitoring is noted as a parallel responsibility.

MN661 Unit 5 questions, answered
How many modalities should the rationale compare?
Three or four is typical when the prompt sets no number. The chosen therapy plus its strongest rival is the minimum that shows a decision was made; more than four usually thins each comparison. Include at least one option that guidelines rank highly for the disorder, since leaving out an obvious candidate is the omission graders catch fastest.
Does the rationale need a specific manual or version?
Naming the version strengthens it. Enhanced CBT, for example, differs from earlier cognitive behavioral treatment for bulimia in its broader, transdiagnostic focus. Citing the manual or its developer shows the choice is a specific treatment rather than a family of techniques, and it lets the evidence cited match the treatment actually proposed in the paper.
Can the client's own preference shape the choice?
It should, and saying so strengthens the paper. A therapy the person will not attend has no effect, so stated preferences, earlier experiences and practical constraints belong in the rationale. The formulation sets the target; preference and feasibility decide among options that reach it. Recording that reasoning openly is more credible than presenting the choice as purely technical.
