Bulimia Nervosa Test (Binge-Purge Screening)
A confidential self-assessment of the binge-purge cycle, informed by the bulimic-symptoms domains of the EDE-Q and the DSM-5 criteria for bulimia nervosa. You get an instant, supportive, plain-language result across binge episodes, compensatory behaviors, and shape and weight concern, plus a professional PDF report you can keep or bring to a clinician.
Bulimia Nervosa Test (Binge-Purge Screening) is a free, confidential 14-question self-assessment, informed by the EDE-Q domains. It takes about 5 minutes, runs entirely in your browser, and gives you a plain-language score across 3 interpretation bands plus a downloadable PDF report. It is an educational screening, not a diagnosis.
The full cycle, not just one half of it
Bulimia is a cycle: episodes of eating that feel out of control, behaviors meant to undo them, and a sense of self that hangs on shape and weight. Screening only one part misses the pattern, so this test looks at all three together.
Binge episodes
Eating unusually large amounts in a short window with a feeling of lost control, plus the secrecy, painful fullness, and guilt that tend to follow. Five items on the binge side of the cycle.
Compensatory behaviors
The attempts to undo eating: self-induced vomiting, laxatives or diuretics, fasting, and driven exercise, along with the repeating cycle they create. Five items on the purge-and-compensate side.
Shape & weight concern
The engine underneath: self-evaluation that depends heavily on shape and weight, fear of gaining, frequent checking, and avoidance. Four items on how much of your worth rides on your body.

How scoring works
Answers are scored 0–42 in total. Your result falls into one of 3 bands:
| Score | Band | What it suggests |
|---|---|---|
| 0–9 | Little sign of the binge-purge cycle | Your answers show little of the cycle of bingeing and compensating this screening looks for. That is reassuring here, though distress about food or your body deserves attention at any score. |
| 10–20 | The cycle may be taking shape | Your answers show parts of the binge-purge cycle taking shape. Cycles like this tend to strengthen with repetition, so this is a genuinely good moment to interrupt it, with help. |
| 21–42 | A strong binge-purge pattern, please reach out | Your answers show a strong binge-purge pattern across episodes, compensation, and how you see yourself. Living inside this cycle is exhausting, and real help exists. Please reach for it. |
Methodology & sources
This is an educational screener, not a reproduction of a single validated instrument. Its fourteen items were written to cover the pattern that defines bulimia nervosa in the DSM-5: recurrent binge episodes involving unusually large amounts of food and a sense of lost control, recurrent compensatory behaviors such as self-induced vomiting, laxative or diuretic use, fasting, or driven exercise, and self-evaluation that is unduly influenced by body shape and weight. The item content is informed by the bulimic-symptoms domains of the Eating Disorder Examination Questionnaire (EDE-Q; Fairburn & Beglin, 1994), the most widely used self-report measure of eating disorder behaviors, with each statement rated on a 0 to 3 frequency scale covering the past month, for a total of 0 to 42.
Because this screener is not a validated instrument, its bands are educational guides rather than clinical cutoffs: lower totals suggest little of the binge-purge pattern, middle totals a pattern worth attention, and higher totals a pattern that warrants professional assessment. A DSM-5 diagnosis of bulimia nervosa also depends on episode frequency and duration, on average at least once a week for three months, which a screening total cannot establish, and compensatory behaviors carry medical risks that only a clinician can evaluate. Whatever your score, if the cycle this test describes feels familiar, that is reason enough to talk with a doctor or an eating-disorder specialist.

Bulimia Nervosa Test (Binge-Purge Screening) FAQ
What is bulimia nervosa?
Bulimia nervosa is an eating disorder built around a repeating cycle: episodes of eating an unusually large amount of food with a feeling of lost control, followed by attempts to compensate through vomiting, laxatives, fasting, or driven exercise, in a person whose self-evaluation depends heavily on shape and weight. Most people with bulimia are in a typical weight range, which is one reason it so often goes unseen.
How is bulimia different from binge eating disorder?
Both involve binge episodes with a feeling of lost control. The difference is what happens next: in bulimia, binges are regularly followed by compensatory behaviors like vomiting, laxatives, fasting, or compulsive exercise; in binge eating disorder they are not. If the bingeing feels familiar but the compensating does not, our binge eating disorder test may be the better fit.
Is purging dangerous even if it's occasional?
Yes, and this is worth saying plainly and kindly. Vomiting and laxative use can disturb the body's electrolytes, which in some cases affects heart rhythm, and repeated purging damages teeth, the throat, and digestion. These risks do not require years of the disorder to appear. This is not said to scare you, but because it is the reason a medical check-in belongs in your next steps, not just a psychological one.
Is this test a diagnosis?
No. It is for education and self-reflection only. A diagnosis of bulimia nervosa depends on episode frequency and duration and on a clinical assessment, including medical evaluation, that only a licensed professional can do. What this screening can do is help you see the cycle clearly and decide to talk with someone about it.
Is the test really confidential?
Yes. It runs entirely in your browser. Your answers are never sent to a server, never stored, and never linked to you. No account is needed, and the optional PDF is generated on your own device.
Can bulimia be treated?
Yes, and the evidence is strong. Cognitive behavioral therapy adapted for eating disorders (CBT-E) is the leading treatment for bulimia, and many people also benefit from medical care and nutritional support. Recovery is genuinely possible, the cycle can be broken, and reaching out earlier tends to make the road shorter. Our general eating disorder test based on the SCOFF is another gentle starting point if you are still finding words for what is happening.
