Muhtasari	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 BSQ is a self-report questionnaire measuring preoccupation with and dissatisfaction about body shape. Originally developed by Cooper and colleagues in 1987, the full version contains 34 items; shorter versions (BSQ-16, BSQ-8) are also widely used. The BSQ was designed to assess body shape concern as a core psychopathological feature of eating disorders and is widely used in eating disorder assessment, body image research, and epidemiological studies.
