תקציר	The TFEQ is a self-report instrument measuring three distinct psychological dimensions of eating behaviour: cognitive restraint (conscious dieting efforts), disinhibition (loss of control over eating when triggered by stress or environmental cues), and hunger (subjective appetite and satiety responsiveness). Developed by Stunkard and Messick in 1985, the original 51-item instrument has been refined into a 21-item version (TFEQ-R21) widely used in obesity research, eating behaviour studies, and nutritional psychology.	The BES is a 16-item self-report questionnaire designed specifically to measure the behavioural and emotional features of binge eating in obese and non-obese populations. Developed by Gormally and colleagues in 1982, the BES uses a forced-choice format and focuses on the subjective experience of loss of control, severity of binge episodes, and affective triggers. It is widely used in obesity treatment research and clinical screening for binge eating patterns.
