תקציר	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.	The Nutrition Self-Efficacy Scale, sometimes called the Diabetes Self-Efficacy Scale (DASES), is an 8-item instrument measuring confidence in performing diet-related behaviors and self-management skills. Developed by Lorig and colleagues at the Stanford Patient Education Center in 2003, it is based on self-efficacy theory and measures respondents' confidence in their ability to eat healthily, manage portions, choose healthful foods, and overcome dietary barriers. The scale is used in diabetes care, weight management, and general nutrition intervention research.
