Validation of ORTO-15 Questionnaire in the group of urban youth aged 15-21

AIM The aim of the study was the validation and adaptation of the ORTO-15 Questionnaire in the group of the Polish schoolgirls and schoolboys. METHODS The study included 399 participants (15-21 years old), all of them high school students in the city of Sosnowiec. The ORTO-15 is a tool created in Italy by L.M. Donini, comprising of 15 items describing intensification of orthorexia risk (population diagnosis). The validation procedure incorporated three basic methods to be applied in the reliability analysis - the comparison of double tests with the same method, the statistical properties analysis of test items as well as analysis of the relation of test items with the general test result. Moreover, the compliance of the ORTO-15 Questionnaire results with other questionnaire focused on eating habits (EAT-26) was studied. RESULTS The reliability analysis of the ORTO-15 Questionnaire based on repeatability of the responses presents a very good (kappa: 0.81 - 1.00 for 5 items) and a good repeatability (kappa: 0.61 - 0.80 for 10 items). The reliability analysis based on the value of the Cronbachs α reached a satisfactory level (0.7 - 0.9). A full agreement of in the occurrence of orthorexia risk and the risk of eating disorders concerned 47.2% (Kappa = 0.04; 95% CI: 0.004 - 0.09) for the Ortho-40 and 88.2% (Kappa = 0.32; 95% CI: 0.17 - 0.47) for the Ortho-35. CONCLUSIONS The ORTO-15 questionnaire is a reliable tool to identify the risk of ON in population studies in the group of urban youth aged 15 - 21.

The assessment of orthorexia nervosa among 1899 Polish adolescents using the ORTO-15 questionnaire

Abstract Objective: Orthorexia nervosa (ON) is considered an eating disorder (ED), with an excessive fixation on the consumption of healthy food and an obsession with its biological purity. Since the adolescent period poses a risk for EDs, the aim of this study was to assess the prevalence of ON in a population of Polish urban adolescents and some possible contributory factors. Method: 1899 high school students, 992 girls and 907 boys aged 15–21 years were studied. Demographic and clinical data were collected using a validated questionnaire including information on preferred living choices, in the context of pro- and antihealth activities. The Polish version of the ORTO-15 questionnaire was used. Results: The mean value of the ORTO-15 was 39.2 ± 3.6 points, with no sex difference. The main factors connected with orthorexia, according to the ‘Orthorexia 33.35 and 40’ definitions were excess weight, sporting activities, out-of-school activities, smoking status, working parents and a high family income. Conclusions: This study, of a large number of adolescents, showed a prevalence of ON similar to that recorded in adult populations. Since factors predisposing to ON in adolescence differ from those for other eating disorders, it is not clear whether ON should be treated as a new form of ED.
