SCOFF Eating Disorder Screener

Before you use the SCOFF screener

The SCOFF questionnaire is a very short screening tool used to flag possible eating-disorder risk. It was designed to be quick enough for primary care, student health, and other everyday settings where a clinician may only have a minute or two to ask focused questions. That speed is useful, but it also means the tool is intentionally simple. A positive score does not prove that someone has anorexia nervosa, bulimia nervosa, or another eating disorder. Instead, it signals that a fuller conversation and possibly a professional assessment would be sensible.

This calculator follows the usual five-question format. You read each statement, check the box if it fits your recent experience, and the page totals your yes answers. The result is a number from 0 to 5, along with a brief interpretation. That sounds straightforward because it is straightforward. The value of the tool is not mathematical complexity; it is the way a few well-chosen questions can reveal patterns around food, body image, weight, and control that might otherwise be hard to name.

It is also important to approach the questions with care. Try to think about recent, real experiences rather than idealized answers or what you feel you should say. At the same time, remember that a low score does not erase distress. Some people with significant symptoms do not check many SCOFF items, especially if their difficulties center on behaviors or diagnoses the tool does not ask about directly. If you feel physically unsafe, deeply distressed, unable to stop harmful behaviors, or worried about self-harm, seek immediate professional help regardless of the number shown here.

The scoring rule is intentionally plain: each checked item counts as 1 point, and each unchecked item counts as 0 points. The calculator simply adds those five values together. If you prefer to see it in formula form, the score is the sum of five yes-or-no answers.

Because the score is so simple, the meaning comes from interpretation rather than computation. Many references use a cutoff of 2 or more yes answers as a positive screen. That threshold is chosen because it tends to be sensitive: it catches more people who may need follow-up. The tradeoff is that some people without a diagnosable eating disorder may also screen positive. In other words, the tool is built to raise a hand and say, this deserves attention, not to give a final answer.

Worked example. Suppose you check the item about making yourself sick when uncomfortably full and the item about losing control over how much you eat, but you leave the other three items unchecked. Your total would be 2 out of 5. That meets the common 2-plus cutoff, so the practical message would be that talking with a clinician, counselor, or other qualified professional is a reasonable next step. The result does not label you, but it does suggest that the concerns are worth exploring in a fuller assessment.

If you use the copy button after calculating, the page prepares a plain-text summary of your score and the items you flagged. That can make it easier to paste the result into a note, a secure message, or a document to discuss at an appointment. The calculation itself happens in your browser on the page; no name, email address, or account is required to use the screener.

What the five SCOFF letters are trying to capture

The name SCOFF comes from the five ideas built into the questionnaire: Sick, Control, One stone, Fat, and Food. The first item asks about making yourself sick because you feel uncomfortably full. In plain language, that means intentionally vomiting after eating, often because of discomfort, panic, guilt, or fear of weight gain. The control item asks whether you worry that you have lost control over how much you eat. People sometimes recognize this as a sense that once eating starts, stopping feels unusually difficult or impossible.

The one-stone item asks about losing more than one stone in a three-month period. One stone is a UK unit equal to 14 pounds, or about 6.35 kilograms. That question is not trying to sort weight loss into good or bad categories; it is looking for noticeable, relatively rapid change over a short time. The first F item, fat, focuses on body image distortion or a persistent belief that you are fat when others say you are too thin. The second F item, food, asks whether food dominates your life, which can show up as constant calorie counting, rigid rules, body checking, anxiety around meals, or feeling that thoughts about food, exercise, or weight crowd out school, work, relationships, or hobbies.

These five items are useful because they are memorable and often clinically relevant, but they do not cover every eating-related problem. The SCOFF does not directly measure binge frequency, laxative misuse, compulsive exercise, chewing and spitting, avoidant or restrictive patterns such as ARFID, or the degree of medical instability. It also does not capture duration, severity, or how much distress is hidden behind outwardly normal routines. That is why it works best as an opening conversation rather than a complete assessment tool.

If a question feels blunt, translating it into everyday language can help. A person may answer yes to the control item even if they never use the word binge, simply because they know the experience of feeling unable to stop. Someone may answer yes to the food item not because they talk about food all day, but because their mind is constantly occupied by rules, fear, or planning. The calculator cannot interpret nuance on its own, so the most helpful use of the score is to combine it with context: what is happening, how often, how long, and with what physical or emotional impact.

How to interpret the result and what to do next

A score of 0 or 1 usually means that fewer classic SCOFF warning signs were captured by these five questions. That can be reassuring, but it is not a guarantee that everything is fine. Some eating disorders, body-image problems, or unhealthy behaviors may not show up strongly in this specific screener. If food, body image, exercise, or weight concerns are causing distress or disrupting daily life, that still matters even with a low total.

A score of 2 or 3 is commonly treated as a positive screen. In practical terms, that means it would be wise to consider speaking with a healthcare professional, therapist, school counselor, or another qualified clinician. A score of 4 or 5 suggests a higher level of concern and makes prompt professional follow-up even more important. The key point is that the screener is about next steps, not labels. It is meant to lower the threshold for reaching out, especially if symptoms have been persistent, secretive, or hard to discuss.

Like all screening tools, the SCOFF can produce both false positives and false negatives. People in intense training, weight-class sports, medically supervised diets, or certain gastrointestinal or endocrine conditions may answer yes for reasons that do not reflect an eating disorder in the usual sense. The opposite can also happen: someone may answer no to several items and still have a serious problem. Cultural context, wording, shame, minimization, and misunderstanding can all change how a person responds. That is why a score should be interpreted alongside history, physical symptoms, and a professional conversation when possible.

Seek urgent medical attention if you notice warning signs such as fainting, chest pain, severe weakness, dehydration, vomiting blood, confusion, inability to keep fluids down, rapid weight change, or thoughts of self-harm. Those situations are not waiting-room questions for an online screener. They are reasons to contact emergency services, a crisis line, or urgent medical care right away. Even when symptoms feel private or embarrassing, medical complications from restriction, purging, and related behaviors can escalate quickly.

If you are concerned about someone else, focus on care rather than appearance. It is usually more helpful to say that you have noticed stress around meals, secrecy, exhaustion, dizziness, or obsessive food talk than to comment on weight or shape. A gentle offer such as I care about you and I am worried, would you like help finding support, can open the door. You do not need to prove that an eating disorder is present before encouraging someone to seek assessment, especially if the behavior seems risky or the person appears medically unwell.

Common questions, privacy, and practical next steps

Can this diagnose me? No. The SCOFF is a screening tool only. It can point toward possible risk, but it cannot confirm or rule out a diagnosis by itself. A proper evaluation may include a conversation about eating patterns, body image, mood, exercise, medical history, medications, menstrual or hormonal changes, substance use, and physical symptoms, along with vital signs or lab tests when appropriate.

What does one stone mean? One stone equals 14 pounds, or about 6.35 kilograms. The question asks whether that amount of weight has been lost over about three months. What if I am still worried after a 0 or 1? You can still seek support. Many people benefit from early conversations before symptoms become more entrenched, and the best time to ask for help is often before things feel extreme.

Is my information stored? The calculator runs in your browser and does not ask for identifying details. The score appears instantly on the page, and the copy feature simply places a plain-text summary on your clipboard. As with any website, your browser or the site itself may still use normal technical functions such as logs, analytics, or cookies elsewhere on the domain, so it is sensible to review the site privacy policy if that matters to you. Can athletes or people on diets score higher for other reasons? Sometimes yes, which is another reason the score should be treated as a conversation starter rather than a verdict.

If you plan to talk with a clinician, it can help to bring more than just the number. Write down which items you answered yes to, when the behaviors or thoughts started, how often they happen, any triggers you notice, and any physical symptoms such as dizziness, stomach pain, cold intolerance, fatigue, missed periods, dental problems, or sore throat. Concrete examples make it easier for a professional to judge risk, recommend next steps, and decide whether medical testing or urgent care is needed.
