Σύνοψη	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 YFAS is a self-report questionnaire measuring symptoms of addictive-like eating behaviour in response to highly palatable foods. Developed by Gearhardt, Corbin, and Brownell in 2009, it is based on diagnostic criteria for substance use disorder and adapted to assess dependence-like symptoms related to food consumption. The YFAS 2.0, released in 2016, improved psychometric properties and reduced item burden. It is used in research on obesity, food addiction, and eating behaviour regulation.
