“…Subsequently, the Greek version of ORTO-R replicated successfully the ndings proposed by Rogoza and Donini [25]. Furthermore, the ORTO-R in the Turkish language conducted by Yargic et al had a comparable result [27], whereas Hallit et al [26] suggested that a two-factor solution in the Arabic version of ORTO-R.…”

“…Additionally, the Cronbach α coe cient of Arabic version ORTO-R was 0.78 and 0.76, respectively [25,26]. The Greek version and Turkish version using the omega coe cient was 0.65 and 0.72, respectively [25,27]. The Cronbach's α were 0.79 and 0.77 of ORTO-15 and ORTO-R in the current study, similar to previous studies [12,13,28], which indicates that a satisfactory internal consistency of the instrument.…”

Purpose: The main objective of the study was to translate, validate, and compare the Chinese ORTO scales (ORTO-15 and ORTO-R). The secondary objective was to assess factors that may be related with risk of orthorexia nervosa (ON). Methods: Two cross-sectional surveys were conducted on March-to-June 2021 for ORTO-15) and April 2022 (ORTO-R). ORTO questionnaires were translated into Chinese using the forward-backward-forward method. Exploratory factor analysis, discriminant validity and con rmatory factor analysis (CFA) were used to examine the construct validity of the assessment questionnaires. The internal consistency was assessed by using the Cronbach alpha coe cient and the test-retest reliability. Multivariate linear regression analysis was used to explore potential impact factors related with ON scores.Results: Totally, 1289 and1084 eligible participants were included for the study of ORTO-15 and ORTO-R, with the mean age of 20.9±2.0 years and 21.0±2.3 years. The internal consistency of Chinese ORTO-15 scale and ORTO-R scale were both satisfactory (α=0.79, ICC=0.79; α=0.77, ICC=0.82). A two-factor solution of ORTO-R was characterized by acceptable goodness-of-t, whereas the three-factor solution of ORTO-15 showed relatively poor t. Multivariate linear regression indicated that physical activities and mental disorders were positively associated with ON risk assessed by both ORTO-R and ORTO-15. Conclusion:The Chinese ORTO-R scale were a more reliable tool to screen for ON tendencies than the Chinese version of ORTO-15. Mental disorders and physical activities might be associated with the increased ON risk.Level of evidence Level V (descriptive cross-sectional study).

“…This demonstrates that the Arabic version of the ORTO-R can be considered a reliable ON screening tool for the Lebanese population. To the best of our knowledge, only one study [ 46 ] investigated the factorial structure of the ORTO-R indicating an acceptable level of model fit and a good reliability (ω = 0.72).…”

Orthorexia nervosa and disordered eating attitudes among Lebanese adults: Assessing psychometric proprieties of the ORTO-R in a population-based sample

2021

Background Previous research demonstrated a relationship between ON and disordered eating symptoms (eating concern, restraint, cognitive preoccupations about body shape and weight) and disordered eating attitudes (DEA). Since screening for orthorexia nervosa is now part of clinical practice, the measurement instruments to be used must be clinically significant, reliable, valid and sensitive to our target population. The main objective of the present study was to confirm the factor structure of the Arabic version of the ORTO-R using a first sample of Lebanese adults and confirm those results on another sample. The secondary objective was to assess sex differences in terms of ON and DEA, as well as to examine whether symptoms of ON were related to DEA in Lebanese adults. Methods A total of 783 Lebanese adults was selected to participate in this cross-sectional study (January-May 2018) using a proportionate random sample from all Lebanese governorates. Results The mean age of the total sample was 27.78 ± 11.60 years (Min. 18 –Max. 84) (33.5% females) and their mean BMI was 24.36 ± 5.31 kg/m2. All items of the ORTO-R were extracted during the factor analysis and yielded a two-factor solution with Eigenvalues > 1 (variance explained = 50.07%; KMO = 0.570; Bartlett’s sphericity test p<0.001; αCronbach = 0.755). This factor structure was confirmed by a confirmatory factor analysis; the Maximum Likelihood Chi-Square = 26.894 and Degrees of Freedom = 8, which gave a χ2/df = 3.36. The Tucker Lewis Index (TLI) value was 0.914, whereas the standardized root mean square residual (SRMR) value was 0.032. The root mean square error of approximation (RMSEA) value was 0.077 [95% CI 0.046–0.111] (pclose = 0.07) and comparative fit index (CFI) value was 0.967 respectively, indicating a good fit of the model. There was also no measurement invariance between genders. Female gender was significantly associated with lower ORTO-R scores (more orthorexia nervosa) compared to males (B = -0.65; p = 0.026, 95% CI -1.22- -0.08; ɳ2 = 0.006). However, no significant difference was found between genders in terms of EAT-26 scores (B = 0.23; p = 0.813, 95% CI -1.66–2.12; ɳ2 = 0.0001). Higher ORTO-R scores (lower/ less pathological ON tendencies and behaviors) were significantly related to higher EAT-26 total scores (higher levels of DEA) as well as higher dieting, bulimia and oral control scores in both females (from a weak to a moderate positive correlation) and males (a weak positive correlation). Conclusion This cross-sectional population-based study confirmed the factor structure of the Arabic version of the ORTO-R, demonstrated an association between ON and DEA and revealed more ON among females compared to males.

“…The questionnaire has also been validated in Arabic ( 46 , 47 ) and Greek ( 48 ), confirming good psychometric properties. A Turkish version has been developed on the basis of the Turkish ORTO-11 ( 49 ). In accordance with the procedures followed by previous studies ( 49 ), although participants filled out the whole ORTO-15 scale, we proceeded in analyzing only the ORTO-R items, changing and reversing the score in order to report it as ORTO-R score.…”

BackgroundThe aim of the present study was to investigate the presence of Orthorexia (ON) symptoms in a sample of University students with or without autistic traits (AT), specifically focusing on evaluating the role of gender and of dietary habits in the association between ON and autism spectrum.MethodsSubjects were requested to anonymously fill out the questionnaires through an online form.ResultsTwo thousand one hundred forty students participated in the study. Subjects with significant AT, measured by means of the Adult Autism Sub-threshold spectrum (AdAS Spectrum) reported significantly higher ON symptoms, as measured by ORTO-R scores, than subjects with low AT. Females and subjects following a vegetarian/vegan diet reported significantly higher ORTO-R scores than males and than subjects following an omnivorous diet, respectively. Significant positive correlations were found between ORTO-R and AdAS Spectrum scores. A decision tree model, with gender, type of diet and presence of high AT as independent variables and ORTO-R score as dependent variable, showed in the first step the presence of significantly higher ORTO-R scores among females than among males, and in the second step showed in both genders the presence of higher ORTO-R scores among subjects with high AT than in those with low AT. A significant interaction of gender and presence/absence of high AT was reported on ORTO-R score, with a higher increasing trend of ORTO-R score with the increase of AdAS Spectrum score among females than among males.ConclusionsOur results further highlighted the association between AT and ON, in particular among females.
