“…The first group maintained nine items and calculated a Cronbach alpha of α = 0.73, while the second one maintained just seven items, calculated a Cronbach alpha of α = 0.83, and confirmed a single-factor model. Finally, an adaptation to Spanish was carried out [39, 40], which confirmed a three-factor structure for an 11-item questionnaire, confirmed a Cronbach alpha of α = 0.75, and established a threshold of 25.…”

Aim The aim of this literature review was to identify the tools developed and used to assess orthorexia nervosa (ON). Methods A systematic search was executed in PubMed, Biomed Central, and PsycINFO. The final list included 70 articles that were critically analyzed. Results A total of six tools were reported to assess ON: the BOT, the ORTO-15, the EHQ, the DOS, the BOS, and the TOS. The tools were based upon different conceptualizations of ON and of its diagnostic criteria. Although they were different, all the conceptualizations derived from the initial definition of ON provided by Bratman in 1997. None of the methodologies adopted for tool construction considered end users or client perspectives and, when carried out, the validations of the tools were fragmented and often based on specific populations. Conclusion This study may be a starting point for the construction of a new diagnostic tool for ON. Starting from the methodological weaknesses identified by this review, it was possible to derive some suggestions for future research: (a) developing a modern re-conceptualization of ON, comprehensive of end-user perspectives; (b) adopting qualitative data collection techniques to gain insights into how to diagnose ON; and (c) actively involving diverse stakeholders for constructing a new tool. Level of evidence Level of Evidence: I, systematic review.

“…In Germany, Depa et al [26] used the DOS and reported prevalence rates of 3.3% of people with ON and 9.0% of people at risk of developing ON among German university students, while in the EEUU the prevalence rate was 8% of ON and 12.4% of people were at risk [24]. In Spain, we found that the adaptation and validation of both scales performed by Parra et al [14,27], had good psychometric properties.…”

In recent decades, orthorexia nervosa (ON) has increased presence in society. It is related with beliefs and attitudes towards eating and is characterized by an obsessive behavior toward heathy eating. The prevalence of ON has been reported by numerous researchers, with rates varying considerably according to the tool used to evaluate the same parameter. The aim of this study was to compare the prevalence of ON in a single population using two different questionnaires. The test for the diagnosis of orthorexia (ORTO-11-ES) assessment tool for orthorexia nervosa and the Düsseldorfer Ortorexie Skala (DOS-ES), constitute brief self-report assessment tools which measure the risk of suffering ON. A sample of 492 students from the University of Castilla la Mancha (Spain) participated in this study, of whom 43.1% were male and 56.9% were female. The findings show that, according to the DOS-ES, only 10.5% of students displayed ON whereas, with the ORTO-11-ES, the prevalence of ON increased to 25.2%. The tendency towards orthorexic behavior is more closely associated with the female gender. The Body Mass Index (BMI) had no influence on the tendency for ON. This study provides valuable information on the usefulness of both questionnaires and the possible limitations associated with the use of these tools in the general population.

“…However, other authors attribute these differences to the structure of the questionnaire itself rather than cultural problems [ 48 ]. Furthermore, when interpreting these results, it is important to consider that the prevalence is linked to the interpretation of different versions of a self-reported questionnaire, which have used different cut-off points [ 11 , 36 , 49 , 50 ] .…”

“…Data collection was performed via a questionnaire prepared by the researchers. The revised questionnaire was divided into three sections: (1) Sociodemographic characteristics; (2) the Eating Disorder Inventory-2 questionnaire (EDI-2) [ 33 , 34 ]; and (3) the ORTO-11-ES [ 35 , 36 ].…”

IntroductionOrthorexia nervosa (ON) is characterized by an obsession with healthy eating, which may lead to severe physical, psychological and social disorders. It is particularly important to research this problem in populations that do not receive clinical care in order to improve early detection and treatment.ObjectiveThe aim of this study was to research the prevalence of ON in a population of Spanish university students and to analyze the possible associations between ON and psychological traits and behaviors that are common to ED.MethodA cross-sectional study with 454 students from the University of Castilla La Mancha, Spain. In total, 295 women and 159 men participated, aged between 18 and 41 years. The ORTO-11-ES questionnaire and the Eating Disorder Inventory (EDI-2) were used for this study. The chi squared test was used to compare the homogeneity among the different groups.ResultsThe scores on the ORTO-11-ES suggested that 17% of students were at risk of ON. The scores on the EDI-2 for the group at risk of ON were significant, compared to the remaining individuals, regarding their drive for thinness (17.1% vs 2.1%), bulimia (2.6% vs 0%), body dissatisfaction (26.3% vs. 12.4%), perfectionism (14.5% vs 4.8%), interoceptive awareness (13.2% vs 1.3%), asceticism (15.8% vs 3.7%) and impulsiveness (9.2% vs 1.9%).Discussion and conclusionThese findings suggest that many of the psychological and behavioral aspects of ED are shared by people who are at risk of ON. Future research should use longitudinal data, examining the temporal relationship among these variables or other underlying variables that may contribute to the concurrence of ED and ON.
