Eating disorder risk is screened with five short yes or no prompts that flag concerning patterns and suggest a next step. This concise five question eating disorder screening test focuses on recent months and gives a total from zero to five. Most people finish in under one minute and see a clear summary they can discuss with someone they trust.
You provide simple answers and the score adds them up, two to five indicates a positive screen and merits further evaluation, zero or one reads negative and you can recheck if concerns grow. The result summarizes the main signals and shows where food concerns, control, weight change, or body image were endorsed.
For example a person who reports recent rapid weight loss and feeling out of control when eating would score two and receive a positive screen, so the next step is to talk with a clinician or support service.
Use a consistent window of the past few months and choose the option that fits best. There are no right or wrong answers and your responses remain on this device.
A screen does not diagnose and it never replaces professional care. If you feel unsafe or unwell seek help now.
The SCOFF questionnaire is a five item screen for possible eating disorder risk. The abbreviation expands to Sick, Control, One stone, Fat, Food, mirroring the five prompts implemented here.
The measurement is a set of five binary responses that reflect three content areas. Eating behaviors are captured by self induced vomiting, loss of control, and food preoccupation. Weight change is captured by a recent loss of more than one stone which equals 6.35 kg within three months. Body image is captured by perceiving fatness despite being told one is underweight.
The computation is the simple count of “Yes” answers. That count is the only index used for the overall result, while companion subscores summarize behavior, weight change, and body image for context. Classification follows a single threshold. A total of two or more is a positive screen and a total of zero or one is negative. A near threshold note appears at one to highlight closeness to the cut point.
| Symbol | Meaning | Unit/Datatype | Source |
|---|---|---|---|
| Self induced vomiting after overeating | 0 or 1 | Input | |
| vcontrol | Loss of control when eating | 0 or 1 | Input |
| vweight | Recent loss > 1 stone in three months (6.35 kg) | 0 or 1 | Input |
| vimage | Feeling fat despite being told one is underweight | 0 or 1 | Input |
| vfood | Food dominates life | 0 or 1 | Input |
| s | Total “Yes” count | Integer 0–5 | Derived |
Two indicates a positive screen. The result highlights behavior and weight change as the primary signals and suggests seeking a professional evaluation.
| Threshold band | Lower bound | Upper bound | Interpretation | Action cue |
|---|---|---|---|---|
| Negative | 0 | 1 | No current indication based on the five prompts | Recheck if concerns grow |
| Positive | 2 | 5 | Possible eating disorder risk flagged | Seek a professional evaluation |
Subscores summarize domains for context. Behavior is the sum of vomiting, loss of control, and food preoccupation with a range of 0–3. Weight change reflects the one stone item and ranges 0–1. Body image reflects the fatness perception item and ranges 0–1.
Units and rounding are simple. Inputs are binary selections and totals are integers, so no rounding rules or decimal separators are applied.

Networking and storage behavior is constrained. Scoring and summaries run on the device and the implementation does not transmit responses to a server. The page may load client assets, but answering the items does not send data.
Privacy and compliance notes: No data is transmitted or stored server‑side. Results are informational and do not constitute a clinical diagnosis.
Eating disorder risk is summarized from five short responses to a clear score and band.
Finish all five items to see your result and suggested next actions.
Two to five indicates a positive screen that merits further evaluation. Zero or one is negative. A one may be labeled near threshold to note proximity to the cut point.
No. Responses are processed on the device and are not sent to a server. The URL can include a short code for your answers, so avoid sharing the link if you prefer privacy.
The weight‑loss item uses more than one stone in three months, which equals 6.35 kg. Answer based on your recent change, not lifetime change.
Scoring runs locally and answering does not send data. If the page is already loaded, results will compute without a connection. Some assets may require an initial load.
Yes. You can copy answers as CSV, download a CSV file, or export a DOCX summary. Exports are created on the device and you control any sharing or printing.
Use the CSV or DOCX export to share selectively. The URL may encode your responses for convenience; only share the link if you are comfortable revealing them.
No. It is a brief screen. Results do not constitute a clinical diagnosis or treatment plan. If you have concerns, talk with a qualified health‑care professional.
Each “Yes” counts as one. The five items are added for a total from 0 to 5. Subscores for behavior, weight change, and body image are shown for context.
