“…In line with these reports, we found that prevalence rates of ON (based on DOS scores of ≥30) were high in inpatients with anorexia nervosa (48%) and bulimia nervosa (33%) in a recent study that tested a large sample of inpatients with mental disorders (22). Furthermore, DOS scores significantly decreased from admission to discharge, although orthorexic eating was not targeted in the eating disorder-specific treatment.…”

“…Further research should verify the compatibility od TON-17 with more valuable ON tools such as EHQ-R, TOS and DOS. A positive correlation between ON and EDs was expected due to previous research and the classification of ON within the eating disorders spectrum [ 1 , 9 , 11 , 13 , 38 , 39 , 40 , 41 , 42 ]. However, Barthels et al [ 37 ] showed that people with restrained eating patterns focus more on quantity than food quality.…”

“…However, individuals with ON focus more on food quality and purity, while people with ED are concerned about the amount and types of food they eat (e.g., sugar or fat is usually excluded from their diet) [ 37 ]. Nevertheless, ON seems to represent a phenomenological subtype of restrictive ED [ 13 , 38 , 39 , 40 , 41 , 42 ].…”

This study aims to develop and validate a new self-report questionnaire to measure orthorexia nervosa (ON). Based on a current review of the scientific literature and interviews with people at risk of orthorexia, 40 items were selected to test orthorexia nervosa (TON-40). A total sample of 767 individuals (M = 26.49, SD = 9.66, 56.98% women) participated in the study. The exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and composite construct analysis (CCA) were performed to find an appropriate model of sufficient reliability and validity and stable construction. Convergent validation was performed regarding the correlation of the TON-17 with another measure of ON (ORTO-15), eating disorders (the EAT-26 and DEAS), healthy behavior (the HBI), quality of life (the Brief WHOQOL), physical health (the GRSH), anxiety (the GAD-7), depression (the PHQ-9), and obsessive-compulsive disorder (the OCI-R). Gender, Body Mass Index (BMI), and the medical reasons for a restrictive diet were also examined. As a result of the structural analyses, the number of items was reduced from 40 to 17. The best fit indices of the TON-17 were found for the hierarchical bi-factor model, with three lower-order factors (Control of food quality, Fixation of health and healthy diet, and Disorder symptoms) and one general higher-order factor (Orthorexia). According to the 95th percentile method of estimation, the prevalence of ON was 5.5% for the TON-17 total score. The TON-17 scale and subscales showed good psychometric properties, stability, reliability, and construct validity. The TON-17 indicated a positive relationship with the ORTO-15, EAT-26, DEAS, HBI, OCI-R, GAD-7, and PHQ-9. TON-17 can be considered as a useful tool for assessing the risk of ON.

“…Regarding its possible nosological classification, there is slightly more research suggesting that orthorexia belongs to the spectrum of eating disorders (e.g. [ 8 , 9 ]) than to the obsessive–compulsive spectrum (e.g. [ 10 ]).…”

Background Orthorexia nervosa, defined as a fixation on eating healthy according to subjective criteria, is recently being discussed as another variant of disordered eating behavior. Further characteristics are rigid adherence to nutritional rules, anxieties and avoidance behavior in the context of eating as well as a focus on health, not on body shape or weight loss, which is supposed to differentiate orthorexic from other disordered eating behavior. Although diagnostic criteria have been suggested, they have rarely been used in case reports published to date. Hence, the aim of this study was to present five individuals with supposed orthorexia nervosa, using preliminary diagnostic criteria to assess their eating behavior. Case presentation The five cases (three females, two males) reveal the great variety of disordered eating behavior. Fear of unhealthy overweight (case A), supposed orthorexic eating behavior as a coping strategy for anorexia nervosa (case B), the exclusive consumption of animal products with a total exclusion of fruits and vegetables (case C), the fixation on exercise and athletic goals (case D) as well as a focus on a vegan diet and unprocessed foods (case E) are facets of orthorexia nervosa with varying degrees of impairment. Conclusions It is concluded that orthorexia nervosa manifests itself in very different ways and that more research is needed in order to determine whether it could be a useful additional category of disordered eating behavior.
