“…Furthermore, this correlation was relatively low, thus supporting the discriminant validity of the I-DOS. Low but signi cant correlation coe cient was also found between I-DOS and the severity of obsessive and compulsive symptoms measured by OCI-R total [27], consistently with previous evidence [47]. This nding reveals that the two conditions may have similar cognitive and behavioral characteristics, as some authors suggest [48].…”

Purpose: Orthorexia Nervosa (ON) is described as an extreme level of preoccupation around healthy eating, accompanied by restrictive eating behaviors. During the years different assessment instruments have been developed. The aim of the study is to adapt into Italian the Düsseldorf Orthorexia Scale (I-DOS) and to test its psychometric properties. Method. A total sample of 422 volunteer university students (mean age = 20.70 ± 3.44, women 71.8%) completed a group of self-report questionnaires in large group sessions during their lecture time. The scales assessed ON (the I-DOS and the Orhto-15), disordered eating (Disordered Eating Questionnaire, DEQ), depressive symptoms (Beck Depression Inventory-II, BDI-II), obsessive and compulsive symptoms (Obsessive Compulsive Inventory-Revised, OCI-R) and self-reported height and weight. Results: The fit of the unidimensional structure and reliability of the I-DOS was tested trough Confirmatory Factor Analysis (CFA) as well as its criterion validity computing correlation coefficients among Ortho-15, DEQ, BDI-II, OCI-R, BMI. Analyses confirmed the unidimensional structure of the I-DOS with acceptable or great fit indices (CFI = 0,984; TLI = 0,978; SRMR = 0.043; RMSEA = 0.076) and the strong internal consistency (α = .888). The Correlations path supported the criterion validity of the scale. The estimated prevalence of ON and ON risk was 8.1%.Conclusions: This 10-items scale appears to be a valid and reliable measure to assess orthorexic behaviors and attitudes.

“…Despite its adverse effects, ON is not included as an eating disorder in the Diagnostic and Statistical Manual of Mental Disorders-5th edition (DSM-5) as of now [4]. Several diagnostic criteria of ON overlap with symptoms of other psychological disorders [2], such as obsessive-compulsive disorder (OCD) [5,6] and Anorexia Nervosa (AN) [7], triggering discussions about its categorical classification [8]. Having said that, the essence differs between ON and AN: the main concern for orthorexic eating behaviors are health and purity while the core of AN is weight loss and food quantity [7].…”

Background There is a lack of studies investigating the possible mediating role of psychological factors, such as depression, anxiety and stress on orthorexic eating behaviors. Given that personality attributes might affect the manifestation of psychological disorders, it was hypothesized that depression, anxiety and stress mediate the relationship between impulsivity-related traits and orthorexic eating, noting that previous research had evaluated the role of depression as a mediator between impulsivity and other pathological eating behaviors. The study objectives were to explore the mediating effect of depression, anxiety, and stress, on impulsivity and orthorexia nervosa, and healthy orthorexia. Methods This cross-sectional study conducted between July and December 2019 recruited 519 Lebanese adults from seven community pharmacies randomly selected from a list provided by the Lebanese Order of Pharmacists. Results Our results showed that depression and anxiety were positively correlated with ON. We also found a notable gender difference in findings: higher anxiety and female gender were significantly associated with higher TOS healthy orthorexia, while higher stress was associated with lower TOS healthy orthorexia. Finally, higher urgency was associated with lower TOS healthy orthorexia, while higher perseverance was significantly associated with higher TOS healthy orthorexia. Depression and anxiety partially mediated the association between perseverance and ON while anxiety and stress partially mediated the association between urgency and healthy orthorexia. Conclusion Our study suggests that depression, anxiety and stress play a mediating role between impulsivity and orthorexia nervosa/healthy orthorexia. Our findings provide a ground for future investigations of impulsive behaviors, psychopathology, and orthorexia in different populations.

“…Higher TOS scores were found in females compared to males. Despite the fact that no or small gender differences were found between male and female groups regarding ON tendency rates [ 30 , 56 , 57 ], many ON-related studies revealed the same problem as our sampling scheme, where females are more represented than males (76.1% of our participants are females) [ 58 , 59 ]. However, aside from ON, disordered eating in general was found to be more susceptible in Lebanese female adolescents where concerns for healthy body image are of a higher grade than in male Lebanese adolescents [ 60 ].…”

Objectives This study aimed at examining the reliability and validity of the Teruel Orthorexia Scale (TOS) among a sample of Lebanese adolescents (15 to 18 years old). Methods This is a cross-sectional study that was conducted between May and June 2020 and had enrolled 555 Lebanese adolescents. To assess the internal structure of the TOS scale, we administered the confirmatory factor analysis based on polychoric correlation matrix using Weighted Least Squares with Means and Variance Adjusted estimation (WLSMV) method in Mplus v 7.2 as suggested in the original validation paper. To assess the degree to which the Lebanese adaptation converges with the original scale, we have conducted the Multigroup Confirmatory Factor Analysis (MGCFA; estimated as CFA) between the data reported in the current paper and from the original validation paper. Results The mean age of the participants was 16.66 ± 1.01 years, with 76.1% females. The bi-dimensional model fitted the data well (χ 2 (118) = 429.09; p < 0.001; CFI = 0.954; RMSEA = 0.069[0.062, 0.076]). The latent factors were highly correlated ( ρ = 0.74; p < 0.001), and the strength of the standardized factor loadings was adequate on both factors (i.e., all > 0.60). The fit indices of the scalar model were at the boundary of the threshold and thus, with some pinch of caution, it might be interpreted as invariant (i.e., having equal item intercepts across groups). We have identified latent mean differences in orthorexia nervosa (0.30; p < 0.001), where Spanish individuals scored higher, but we did not find any differences in the healthy eating (0.03; p = 0.636). Higher DOS scores were significantly correlated with higher scores on the TOS subscale OrNe ( r = 0.715; p < 0.001) as well as with higher scores on the TOS subscale HeOR ( r = 0.754; p < 0.001). Higher ORTO-R scores were significantly associated with less TOS OrNe ( r = − 0.437; p < 0.001) and TOS HeOr ( r = − 0.305; p < 0.001) scores, respectively. Conclusion The Arabic version of the TOS can be considered a reliable valuable instrument to assess the ON tendencies and behaviors in Lebanese adolescents, emphasizing the fine contrast between ON’s two dimensions: healthy vs. pathological. Level V Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.
