Three-Factor Eating Questionnaire (TFEQ)
The Three-Factor Eating Questionnaire is a validated set of questions that scores three eating styles - cognitive restraint, uncontrolled eating and emotional eating - which shape how a person responds to a weight plan.
Plain English
Patient-Friendly Explanation
The Three-Factor Eating Questionnaire, usually shortened to TFEQ, is a set of questions that sorts eating behaviour into three patterns instead of treating everyone the same. Cognitive restraint is how deliberately a person holds back - taking small helpings, avoiding foods they think are fattening. Uncontrolled eating is the feeling of losing control once eating starts: being easily triggered by the sight or smell of food, or feeling hungry again soon after a meal. Emotional eating is eating more when stressed, low or lonely. The original version, published in 1985, had 51 questions covering restraint, disinhibition and hunger. A shorter 18-question version was built in 2000 from a Swedish study of more than 4,000 adults with obesity, and that is the version most clinics and researchers use today. Filling it in takes a few minutes and there are no right or wrong answers - it describes a pattern, not a score of willpower. Two people can weigh exactly the same and have completely different profiles: one who has been rigidly restricting and then bingeing, another who eats mainly when upset. The answers tell the doctor which problem to treat first, and whether a psychologist or dietitian will help more than another diet sheet.

Clinical Definition
The original Three-Factor Eating Questionnaire (Stunkard and Messick, 1985) contained 51 items measuring cognitive restraint, disinhibition and hunger, but its factor structure was not replicated in later large samples. Karlsson and colleagues (2000) re-derived the instrument in the Swedish Obese Subjects cohort of 4,377 middle-aged men and women with obesity, producing the 18-item TFEQ-R18 with three subscales: cognitive restraint (6 items), uncontrolled eating (9 items) and emotional eating (3 items). Items 1 to 17 use a four-point Likert response and item 18 an eight-point rating collapsed to four points, and some protocols reverse-score the first 13 items. Internal consistency in the derivation and general-population samples was 0.75 and 0.78 for cognitive restraint, 0.89 and 0.87 for uncontrolled eating and 0.87 for emotional eating, and the three-factor structure has been reproduced in independent cohorts including adolescents and adults at metabolic risk. Clinically the subscales carry prognostic weight: high uncontrolled or disinhibited eating predicts poorer adherence and weight regain after lifestyle and surgical treatment, rigid restraint predicts short-term loss followed by counter-regulatory overeating, and high emotional eating overlaps with binge-spectrum presentations and argues for psychological assessment before a very restrictive plan is prescribed. The questionnaire is a phenotyping tool rather than a diagnostic instrument, and is often combined with the Dutch Eating Behaviour Questionnaire and the Power of Food Scale.
Key Insight
Why It Matters
The TFEQ explains why the same advice works for one person and backfires for another - it separates deliberate restraint from loss of control and from eating for comfort, so the plan can target the real pattern.
