The Three-Factor Eating Questionnaire (abbreviated as TFEQ) is a questionnaire often applied in food intake-behavior related research. It goes back to its publication in 1985 by Albert J. Stunkard and Samuel Messick.[1]
The TFEQ contains 51 items (questions) and measures three dimensions of human eating behavior:
Each item scores either 0 or 1 point. The minimum score for factors I-II-III is therefore 0-0-0, the possible maximum score 21-16-14. There exist revised versions of this scale with reduced numbers of items: the TFEQ-R18 with 18 items[2][3] and the TFEQ-R21 with 21 items.[4]
