This is a clinical instrument. It is not publicly self-administered; a clinician assigns it through a secure patient link.

You learn whether your eating habits show warning signs worth talking about.

For anyone who wants a quick, private check on their relationship with food.

It comes from medical screening research on brief questions for eating disorders.

What it measures

Five yes-or-no questions make up the screen, and their key words give it its name: whether a person makes themselves Sick because they feel uncomfortably full, worries that they have lost Control over how much they eat, has recently lost more than One stone (about six kilograms) in three months, believes themselves to be Fat when others say they are too thin, and would say that Food dominates their life.

Morgan, Reid and Lacey (1999) developed the questions in the United Kingdom as a simple, memorable screen that non-specialists could use to raise the possibility of anorexia nervosa or bulimia nervosa in a brief consultation.

Each yes answer adds one point. Lower totals indicate few signs of an eating disorder; higher totals indicate more, and the report explains what each level tends to mean. A positive screen suggests that a fuller assessment of eating, weight and health is warranted; it is not a diagnosis.

The questionnaire is used in primary care, student health and research as a first step in identifying eating difficulties. On this site, the Eating Attitudes Screen describes eating attitudes and weight preoccupation dimensionally, and the PHQ-9 and GAD-7 describe mood and anxiety, which often accompany eating difficulties.

Validity evidence

At the published cutoff, sensitivity is about 0.85-1.00 and specificity about 0.80-0.90 for anorexia and bulimia in the original validation (Morgan et al., 1999).

Example item

Sample report preview

The report shows your total score and where it falls across the range of possible scores, followed by a plain-language explanation of what scores in that region describe. Where the instrument has published interpretive bands, the report names the band and what it means. It closes with notes on how to read the result and on when a conversation with a qualified professional may be useful.
