OSFED Test (Other Specified Feeding or Eating Disorder) is a free, confidential 20-question self-assessment, original 20-item screener informed by DSM-5-TR · not a diagnostic instrument. It takes about 5 minutes, runs entirely in your browser, and gives you a plain-language score across 4 interpretation bands plus an optional in-depth report. It is an educational screening, not a diagnosis.

One screener for the eating disorder that does not fit the famous labels

Most online eating disorder quizzes test for anorexia or bulimia and leave everyone else with a blank. OSFED is the diagnosis for serious eating problems that fall just outside those definitions, and it is the most common eating disorder diagnosis in clinical samples. This test asks 20 plain questions about the past three months and reports the pattern behind your answers.

All five OSFED presentations

Atypical anorexia, bulimia of low frequency or short duration, binge eating of low frequency or short duration, purging disorder, and night eating syndrome. Four questions each, written in plain language from the DSM-5-TR descriptions.

The presentation that stands out

Your result shows an overall level plus a breakdown bar for each presentation, so you can see whether your answers cluster around restriction, binge episodes, purging, or night eating rather than getting a single vague score.

No weight gate

Many quizzes quietly assume an eating disorder means being underweight. Atypical anorexia is defined by restriction and fear of weight gain at any weight, and this test treats it that way.

How scoring works

Answers are scored 0–60 in total. Your result falls into one of 4 bands:

ScoreBandWhat it suggests
0–14Few signs of OSFEDYour answers show few of the patterns this test screens for. Across the five presentations, nothing stood out strongly over the past three months.
15–29Some signs of OSFEDYour answers show some of the patterns this test screens for. At least one presentation is probably showing up for you more than occasionally.
30–44Significant signs of OSFEDYour answers show significant signs of the patterns this test screens for. The pattern is likely costing you something already, in energy, mood or how much of your day food takes up.
45–60Strong signs of OSFEDYour answers show strong signs across the patterns this test screens for. This is a lot to carry, and it is treatable.

How the OSFED test is scored

The test has 20 statements about the past three months, four for each of the five OSFED presentations. You rate each from 0 (never) to 3 (often), so the overall score runs from 0 to 60 and each presentation scores from 0 to 12. The overall score places you in one of four educational bands: few signs, some signs, significant signs, or strong signs. The bands are house-made quarters of the range chosen for readability, not clinical cutoffs from a validated instrument, because no validated self-report questionnaire exists that scores OSFED as a whole.

The breakdown is where the useful information sits. OSFED is not one condition but a group, and the five presentations call for different conversations with a clinician. Look at which bar is highest. If two bars are close, that is common: binge eating and purging often travel together, and night eating frequently sits alongside daytime restriction. The breakdown groupings are ours, drawn from the DSM-5-TR descriptions rather than from factor analysis, and they are a map for reflection rather than a measurement of five separate disorders.

EDNOS, OSFED, and why 'other specified' does not mean milder

Until 2013 the DSM-IV used the label Eating Disorder Not Otherwise Specified, or EDNOS, for anyone whose eating problem was clearly serious but did not match the full criteria for anorexia nervosa or bulimia nervosa. EDNOS became the most common eating disorder diagnosis in clinics, which was awkward: the catch-all category was bigger than the named ones. The DSM-5 renamed it Other Specified Feeding or Eating Disorder, moved binge eating disorder out into its own diagnosis, and named five example presentations so that clinicians could specify what they were seeing. The DSM-5-TR keeps that structure. If you searched for an EDNOS quiz, this is the current version of what you were looking for.

The word 'other' misleads people into reading OSFED as a lighter diagnosis. It is not. Research in community and clinical samples finds that people with OSFED report levels of distress, impairment and medical risk comparable to those with anorexia or bulimia, and OSFED remains the most frequent eating disorder diagnosis in many treatment settings. Someone with atypical anorexia can have the same heart-rate changes, electrolyte problems and bone loss as someone who is underweight. Someone who purges after normal meals carries the same medical risk as someone who binges first. A person whose binge-purge cycle happens three times a month instead of four times a week is not three-quarters as unwell. The label describes which boxes were ticked on a form, not how much help a person needs.

One medical point deserves its own sentence: purging of any kind, including self-induced vomiting and laxative or diuretic use, can disturb the body's potassium and fluid balance, and fainting, dizziness or heart palpitations after purging are reasons to see a doctor promptly, whatever this test says.

OSFED compared with anorexia, bulimia, binge eating, ARFID and orthorexia

If your breakdown points to atypical anorexia, the Anorexia Nervosa Test (Eating Attitudes Screening) test looks more closely at restriction and body image attitudes. If it points to low-frequency bulimia or purging disorder, the Bulimia Nervosa Test (Binge-Purge Screening) test screens the binge-purge cycle in more detail. If it points to low-frequency binge eating, the Binge Eating Disorder (BED) Test covers binge episodes without compensation. The general Eating Disorder Test is the broad screen many people start with; this page is the follow-up for those whose eating problem did not fit neatly into it.

Two conditions are often confused with OSFED but sit elsewhere. ARFID, screened at ARFID Test, is restriction driven by sensory sensitivity, low interest in eating or fear of choking or vomiting, not by weight or shape concerns; it has its own diagnosis. Orthorexia, screened at Orthorexia Test, describes a fixation on eating 'correctly' or 'purely' and is not a DSM-5-TR diagnosis at all, although when it involves restriction and weight concern it may be recorded as OSFED. Night eating syndrome is the OSFED presentation people least often recognize in themselves, because eating late can feel like a habit rather than a symptom; the defining features are eating a large share of the day's food after dinner or on waking at night, being fully awake while doing so, and feeling distressed by it.

What to do with your result

A result in the few-signs band is reassuring for the behaviors this test asks about, but if food, weight or shape still take up more of your thinking than you would like, that is worth attention on its own terms. A result in the some-signs band is a good moment to talk with your doctor or a therapist who works with eating concerns, before the pattern settles in; early help shortens the road back. Significant or strong signs mean the pattern is already costing you something, and the most useful next step is an assessment with a clinician who treats eating disorders, who can also check the medical basics such as electrolytes, blood pressure and heart rhythm.

Whatever your score, you do not have to be 'sick enough' to deserve help. That belief keeps many people with OSFED from asking, precisely because their eating problem never looked like the version in films. Bring your result to the conversation if it helps you find the words. In the US, the National Alliance for Eating Disorders runs a helpline, and if you are ever in crisis you can call or text 988 any time.

Methodology & sources

This is an original educational screener. The 20 items were written by Psychology.com from the DSM-5-TR descriptions of the five presentations listed under Other Specified Feeding or Eating Disorder (American Psychiatric Association, 2022): atypical anorexia nervosa, bulimia nervosa of low frequency and/or limited duration, binge eating disorder of low frequency and/or limited duration, purging disorder, and night eating syndrome. Each presentation gets four plain-language items about the past three months, rated on a 0 to 3 frequency scale. No item is copied from a proprietary or validated questionnaire; the wording is ours. The test is therefore not validated, and the four result bands are house-made divisions of the 0 to 60 range for educational use, not clinical cutoffs.

The five-presentation breakdown is our own grouping based on the diagnostic descriptions, not an empirically derived set of subscales, and it should be read as a map of where your answers cluster. Research supports the seriousness of what it maps: in a large community study of young women, Stice and colleagues (2013) found that the proposed DSM-5 'other' eating disorders were common and carried marked impairment, and Fairweather-Schmidt and Wade (2014) found that adolescents with OSFED could not be distinguished from those with full-threshold disorders on impairment or risk factors. A systematic review of prevalence by Galmiche and colleagues (2019) confirms that OSFED is among the most common eating disorder diagnoses across samples.

The references support the structure of the diagnosis and its seriousness; they do not validate this particular questionnaire. Only a clinician can assess an eating disorder, and the medical checks that matter most (electrolytes, heart rhythm, bone density) are not things any online test can measure.

OSFED Test (Other Specified Feeding or Eating Disorder) FAQ

What is OSFED?

OSFED stands for Other Specified Feeding or Eating Disorder. It is the DSM-5-TR diagnosis for a serious eating problem that causes real distress or impairment but does not meet every criterion for anorexia nervosa, bulimia nervosa, binge eating disorder or ARFID. The manual lists five example presentations: atypical anorexia, low-frequency bulimia, low-frequency binge eating, purging disorder and night eating syndrome. It is the most common eating disorder diagnosis in many clinical settings.

Is OSFED the same as EDNOS?

Nearly. EDNOS (Eating Disorder Not Otherwise Specified) was the DSM-IV name for the same idea. The DSM-5 in 2013 renamed it OSFED, split binge eating disorder off into its own diagnosis, and named the five presentations so clinicians could be specific. If you were looking for an EDNOS quiz, this test covers the current version of that category.

Is OSFED less serious than anorexia or bulimia?

No. Studies comparing OSFED with full-threshold eating disorders find similar levels of distress, impairment and medical risk. Atypical anorexia can cause the same heart, electrolyte and bone problems as anorexia at a low weight, and purging after normal meals is as dangerous as purging after binges. The label reflects which criteria were met, not how much help someone needs.

Is this test a diagnosis?

No. It is an original educational screener for adults, not a validated instrument, and only a clinician can assess an eating disorder. A high score is a reason to book an assessment; a low score does not rule anything out. For a broader first screen, the eating disorder test covers the common patterns in one pass.

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.

Which test should I take next?

Follow your highest breakdown bar. Restriction and fear of weight gain point to the anorexia test; binge-purge cycles to the bulimia test; binge episodes without compensation to the binge eating test. If your eating is restricted for sensory or fear reasons rather than weight, see the ARFID test; if it centers on eating 'correctly', the orthorexia test.

Important: This OSFED test is an educational screening tool, not a medical or psychological diagnosis. It cannot tell you whether you have OSFED or any other eating disorder; only a qualified clinician can assess that, and some of the risks involved (electrolytes, heart rhythm, bone health) require medical tests. If you feel faint, dizzy or notice heart palpitations after purging, see a doctor promptly. If you are in crisis, call your local emergency number or, in the US, call or text 988 any time.
