Eating Attitudes Test (EAT): A self-report screening measure developed to help individuals determine if they might have an eating disorder that needs professional attention. It was not designed to make a formal diagnosis of an eating disorder or to replace professional treatment but to be used as a diagnostic or screening tool. It's a brief, 26-item standardized, self-report screening test of symptoms and concerns characteristic of eating disorders; takes about 5-10 minutes to complete.
