خلاصه	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 SCOFF is a five-question screening tool for eating disorders, developed by Morgan, Reid, and Lacey at the University of Leeds in 1999. Its acronym—Sick, Control, One, Fat, Food—represents its five core items. The SCOFF is exceptionally brief, takes less than 2 minutes to administer, and was designed to identify cases of anorexia nervosa and bulimia nervosa in primary care and medical settings. It remains one of the fastest and most widely used screening instruments globally.
