“…After a factoranalysis of 15 items of the ORTO-15 questionnaire, the authors chose the items of factor weight ≥ 0.5 for the short test version (ORTO-11) and determined the reliability of ORTO-15 at the Cronbach's alpha level of 0.44 and 0.62 for ORTO-11. In the following years, other authors adapted ORTO-15 to the country of their study, which led to many versions of the test, e.g., ORTO-12 [5], the Polish version of ORTHO-15 [53], ORTO-11-Hu [54], ORTO-9-GE [55], the English version of ORTO-15 [23,56], ORTO-11-ES [57], ORTO-12-FR [58], and ORTO-6 [59]. These versions differ in terms of the number of items, factors, maximum number of points, cut-off points, and psychometric features.…”

The aim of this article is to present the up-to-date diagnostic tools of orthorexia and markers of its prevalence on the basis of the available literature. The authors searched PubMedCentral (PMC) and Google Scholar with the search entry of “orthorexia”, “orthorexia nervosa”, and “orthorexicbehaviours”. We describe the tools of evaluation of orthorexicbehaviour (i.e., orthorexia self-test—BOT, the ORTO-15 questionnaire, Eating Habits Questionnaire—EHQ, Düsseldorf Orthorexia Scale—DOS, Teruel Orthorexia Scale—TOS, Barcelona Orthorexia Scale—BOS, and Orthorexia Nervosa Inventory—ONI), and offer a review of the studies on orthorexia nervosa. We conclude that there are no reliable data regarding the prevalence of orthorexia nervosa. The available studies point to significant differences in the prevalence depending on the value of cut-off points and tools used. The prevalence varies across countries and across populations, ranging from 6.9% in the Italian population to 88.7% in the group of Brazilian students of dieting. Thus, it indicates that some groups seem to be susceptible to the risk of ON more than others. It is a challenge to determine the prevalence of orthorexia, and any obtained results should be treated with caution. Consequently, we claim that the use of the ORTO-15 questionnaire to diagnose orthorexia is questionable due to a high percentage of falsely positive results.

“…While the individuals with the lowest score was de ned as the group with ON, but some of them with the lowest score were observed to have healthy eating behaviors and normal personality and this is not discussed by researchers [3,26]. In the following years, several versions of ORTO-15 with different item number, factor number and cut-off scores were developed [44][45][46][47]. Therefore, the usability of ORTO-15 has been questioned by many studies due to the high frequency of ON in the groups studied, the lack of information about how the items are created, and the lack of a clear validated tool [3,4,17].…”

Background There are several scales to evaluate orthorexia nervosa (ON), a pathological obsession, fixation or preoccupation with healthy foods. However, studies report that some of these scales have poor internal consistency and some do not have test-retest reliability, therefore new scales are needed to evaluate ON correctly. This study aims to adapt the Test of Orthorexia Nervosa-17 (TON-17) into Turkish and verify its validity and reliability. Methods The study included a total of 539 adults, 131 men (24.3%) and 408 women (75.7%), with a mean age of 30.2 ± 12.26 years. A reliability analysis was performed and a confirmatory factor analysis (CFA) to test its construct validity. Time invariance of the scale was examined by test-retest analysis, and its convergent validity was evaluated by a correlation analysis conducted to test relationships between the scale and other theoretically relevant instruments (EAT-26 and OBQ-9). Analyses were conducted using SPSS Version 23 and the AMOS program. Results The Cronbach's α internal consistency coefficient of the total scale was found to be 0.820, suggesting a strong internal consistency. The Cronbach's α values of its factors were 0.681 for the Factor 1, 0.643 for the Factor 2, and 0.726 for the Factor 3. In addition, the test-retest reliability was found as 0.868 for the total scale, suggesting an excellent reliability. The most of fit indices (CMIN/df, RMSEA, AGFI, NFI and TLI) of the scale were acceptable, and the GFI indicated a good model fit. Conclusion This study has shown that the Turkish version of TON-17, which is a new tool with three-factor structure to evaluate both healthy and unhealthy orthorexia, is valid and reliable scale. Studies of TON-17 on diverse cultures will contribute to the literature. Therefore, examining the validity and reliability of TON-17 in diverse cultures and populations may contribute to developing the gold standard scale for evaluating ON in future studies.

“…In this present study, ORTO-12-FR was used to assess orthorexic traits among the sample ( 59 ). ORTO-12-FR is a shorter French version of the ORTO15 developed by Donini et al ( 21 ), with three items deleted after a confirmatory factor analysis (items 5, 6, and 8).…”

Sinful Foods: Measuring Implicit Associations Between Food Categories and Moral Attributes in Anorexic, Orthorexic, and Healthy Subjects

et al. 2022

Recently, neurocognitive studies have shown that food categorization is sensitive to both the properties of the food stimuli (e.g., calorie content) and the individual characteristics of subjects (e.g., BMI, eating disorders) asked to categorize these stimuli. Furthermore, groups of patients with eating disorders (ED) were described as relying more on moral criteria to form food categories than were control subjects. The present studies built on these seminal articles and aimed to determine whether certain food properties might trigger moral categories preferentially in subjects suffering from ED and in the general population. Using a Go/No-Go Association Task, Study 1 focused on the extent to which food categories are laden with moral attributes in ED patients compared to control subjects. Study 2 was a follow-up with a different design (an Implicit Association Test), another food variable (calorie content), and two non-clinical subgroups (orthorexic and healthy control subjects). Results revealed for the first time implicit associations between food variables cueing for energy density and moral attributes in the general population, the population suffering from anorexia nervosa, and subjects suffering from disordered eating such as orthorexia nervosa. These findings suggest that moralization of food is a pervasive phenomenon that can be measured with methods reputed to be less vulnerable to self-presentation or social desirability biases.
