Self-report questionnaire My Eating Habits was developed to assess influence eating habits and psychological factors in pathogenesis of overweight and obesity. It consist of 30 items, which include statements regarding weight, dieting, behaviours, attitudes associated with eating. My Eating Habits questionnaire was validated on a normal and overweight sample. Reliability of the questionnaire was assessed by internal consistency (Cronbach’s alpha) and it was high – 0.89. Factor analysis yielded three factors, which explained 37.5% of the total variance: factor 1 – habit overeating, factor 2 – emotional overeating, 3 – restraint from eating. My Eating Habits questionnaire can distinguish reliably between subjects with overweight and normal weight. It may also identify subjects in the general population who are at risk for developing eating disorders, in particular overeating. The results of the study indicate that My Eating Habits questionnaire is a reliable and valid method, but it should be invaluable in long-term studies and in different groups, among them in subjects with anorexia nervosa and bulimia.
