Validation of the Greek ORTO-15 questionnaire for the assessment of orthorexia nervosa and its relation to eating disorders symptomatology.
Eat Weight Disord. 2021 Dec; 26(8):2471-2479.EW

Abstract

PURPOSE

The aim of the study was the validation of the Greek version of the ORTO-15 questionnaire. An additional aim was to explore the relation between orthorexic and eating disorder behaviors in a sample of Greek students.

METHODS

ORTO-15 was translated and adapted in the Greek language. After its final version was drafted, its test-retest reliability was checked. Then, the questionnaire was administered to 120 students of psychology along with EAT-26. Additionally, demographics, BMI and information related to eating disorders were collected.

RESULTS

The Greek version of the ORTO-15 questionnaire showed acceptable internal consistency (Cronbach's a 0.7). Factor analysis produced a three-factor model similar to the original English version of the questionnaire. The correlation of ORTO-15 and EAT-26 revealed that higher measurements in the diet and bulimia EAT-26 scale were related to increased orthorexic symptomatology. Finally, there was no significant correlation between the 3 factors of the ORTO-15 (emotional, rational and behavioral) and age, education or Body Mass Index.

CONCLUSIONS

This study is the first attempt to assess orthorexia nervosa in a Greek student population. ORTO-15 was found to be a reliable tool for the measurement of orthorexia in Greece. Finally, in accordance with other studies, orthorexic symptoms were partially related to eating disorder symptomatology, thus raising the question of possible similarities and overlap between the two clinical constructs.

LEVEL OF EVIDENCE

Level V, Cross-sectional descriptive study.
