DOS: Duesseldorf Orthorexia Scale sum score; WREQ: Weight-Related Eating Questionnaire; EDE-Q8: Eating Disorder Examination-Questionnaire brief version; MEDAS: Mediterranean Diet Assessment Tool; Y-BOCS: Yale–Brown Obsessive–Compulsive Scale; R2: coefficient of determination, that is, variance in criterion explained by predictors, F: F-tests to test the overall significance for the regression model.
