概要	The Intuitive Eating Scale-2 is a 23-item self-report instrument designed to measure intuitive eating, a non-restrictive, non-prescriptive eating approach that emphasizes internal hunger and satiety cues, unconditional permission to eat, and body attunement. Developed by Tylka and Kroon Van Diest in 2013, the IES-2 builds on the original Intuitive Eating Scale and has become a standard measure in research examining health-at-every-size, eating disorder recovery, and alternatives to restrictive dieting. It is widely used in clinical research and eating behavior studies.	Body image satisfaction and dissatisfaction are important psychological constructs measured through multiple instruments, with no single standardized 'Body Weight Image and Satisfaction Scale,' but rather several validated measures of body dissatisfaction (e.g., EDE-Q body dissatisfaction items, Figure Rating Scale, Body Shape Questionnaire). These instruments assess the degree to which individuals are satisfied with their body weight and shape, a key psychological outcome in nutrition, eating disorder, and weight management research. Body dissatisfaction is strongly associated with disordered eating, poor mental health, and reduced quality of life.
