Bulimia Nervosa Test (Binge-Purge Screening): Screen Your Binge-Purge Patterns
This bulimia nervosa test screens for binge eating, compensatory behaviors, and body image concerns using EDE-Q-informed questions. Get an instant screening result and a breakdown of your pattern.
Reviewed by Michael Callans, MSW 
Bulimia Nervosa Test (Binge-Purge Screening) is a free, confidential 14-question self-assessment, informed by the EDE-Q domains. It takes about 7 minutes, runs entirely in your browser, and gives you a plain-language score across 3 interpretation bands plus an optional in-depth 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. |
What should I tell a doctor after a bulimia nervosa test?
A bulimia nervosa test can help you describe eating that feels out of control, attempts to compensate, and distress about body shape or weight. Bring examples of the behaviors you recognized, including anything that feels difficult to say aloud. Your result can start the conversation even when you are unsure whether the word bulimia fits.
Tell the clinician about vomiting, laxative or diuretic use, fasting, driven exercise, and any physical symptoms. Medical assessment matters because purging can disturb fluid balance and electrolytes even when body weight appears typical. Chest pain, fainting, or trouble breathing after purging needs urgent medical attention. These complications are described in the Mehler and Rylander review listed below.
If speaking about the behaviors feels difficult, you can hand the clinician a written note or ask a trusted person to help you explain. Include when the pattern began, how it has changed, and any medicines or supplements you use. Ask what medical checks are appropriate and how eating-disorder care will be coordinated. You do not have to arrive with a diagnosis or a perfectly detailed account.
Where can I find support for eating and body image concerns?
The Eating Disorder Test offers broader screening, while the Binge Eating Disorder (BED) Test focuses on binge-eating concerns. You can find these through the Psychology.com tests hub. Additional self-assessments are optional; you can contact a clinician directly with the concerns you already have.
The Body Image Worksheet offers space to put body-related thoughts into words before an appointment. Use it for reflection alongside professional support. The Psychology.com therapist directory can help you look for a clinician who works with eating disorders, and your primary care clinician can assess physical health concerns.
Can a low bulimia test score miss an eating disorder?
Yes. This original bulimia nervosa test adds together self-reported experiences, so the total can be low even when a particular behavior needs attention. It cannot determine electrolyte levels, heart rhythm, nutritional status, or whether you meet diagnostic criteria. The result bands are educational descriptions, and the research on the EDE-Q does not establish their accuracy.
Read the behaviors you recognized alongside the total. Purging, distress about eating, or exercise that feels compulsory deserves discussion even when other statements do not fit. Eating disorders can affect people across body sizes, as NIMH explains. You do not need a change in weight, a higher score, or certainty about the name of the problem before asking for an assessment.
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.
Once a clinician confirms a diagnosis, the DSM-5 grades bulimia nervosa's severity by how often compensatory behaviors happen each week: mild is one to three episodes, moderate is four to seven, severe is eight to thirteen, and extreme is fourteen or more (American Psychiatric Association, 2013). This screener's frequency scale mirrors that same logic in spirit, occasional versus regular versus very often, which is why the compensatory behaviors domain carries as much weight in the total as the binge episodes themselves.
The EDE-Q research supports the source questionnaire, not the accuracy of this original bulimia nervosa test. Its wording, response options, and educational score bands have not been validated as an equivalent version of the EDE-Q. A low total cannot rule out an eating disorder or show that purging is medically safe.

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 individual answers are scored in your browser and are never sent to us or linked to you. They stay in this tab so you can return to your result, and closing or clearing the tab clears them. If you ask us to email the PDF, we receive your summary scores with your email address, never your individual answers. No account is needed.
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.
