The Three-Factor Eating Questionnaire is a self-assessment scale used widely in studies of eating behavior in overweight and normal weight individuals. It assesses three cognitive and behavioral domains of eating: cognitive restraint (6 items), uncontrolled eating (9 items) and emotional eating (6 items). It comprises 21 items in a four-point Likert scale for items 1–20 and on an eight-point numerical rating scale for item 21. Responses to each of the items are given a score between 1 and 4. Before calculating domain scores, items 1–16 were reverse coded and item 21 was recoded as follows: 1–2 scores as 1; 3–4 as 2; 5–6 as 3; 7–8 as 4.
