Psychometric evaluation of the French version of the Düsseldorfer Orthorexia Skala (DOS) and prevalence of orthorexia nervosa among university students

Eating disorders is a general term used for grouping all the problems related to eating attitudes under one title and for expressing these problems. Orthorexia nervosa (ON), also known as “obsession of healthy eating” recently happened to be the research topic of clinicians worldwide. This study was conducted to evaluate the association between eating attitudes and orthorexia nervosa in university students. The research population was comprised of 379 university students in the departments of nutrition and dietetics and nursing. The data was collected by the survey form questioning some of the socio-demographic and anthropometric properties of the students; and as for the data collection tool, ON tendency was determined by ORTHO-11 test and the information regarding anorexia and buliminia nervosa was gathered by “Eating Manner Test (EAT-40). Mean age of the students was found as 20.09±1.47 years, mean body weight as 60.55±10.01 kg, and mean height as 168.08±7.91 cm. Mean BMI of the all participating students is found as 21.6±2.12 as normal weight (18.5-24.9). EAT-40 points of the female were found to be significantly higher in comparison to that of the male (p<0.05). ORTHO-11 points of the male students were found to be significantly higher as compared to that of female students (p<0.05). Eating disorders will tend to increase as long as the concepts of beauty, good look and appeal are based on low body mass index. We also believe that the youg population who are most influenced by such popular trends need to acquire truly healthy nutrition habits through training and increase their quality of life.

Abstract There is limited evidence of a link between Orthorexia Nervosa (ON) and Obsessive–Compulsive Disorder (OCD), and no definitive conclusions can be drawn. The interplay between socio-cultural context and ON has been poorly investigated as well. Therefore, the objectives of the present study were: (1) to investigate the differences in ON and OCD symptoms and (2) to assess the relationship between ON and OCD symptoms among university students. Six hundred and sixty-six university students participated in the present study: 286 from Poland and 320 from Italy. No age, gender and marital status differences were identified between two samples of university students. However, on average, Polish university students had a higher Body Mass Index than Italian ones. Our findings showed that Polish students present more problems related to obsessive symptomatology, core beliefs of OCD, perfectionism traits, and a major ON symptomatology than Italian ones. Also, Polish students with a higher level of ON exhibited higher levels of OCD symptoms and parental expectations/parental criticism. While Italian students with a higher level of ON showed higher levels of perfectionism features (organization and concern over mistakes). In general, correlations were low as confirmation of partial independence ON from OCD symptoms and core beliefs of OCD in both Polish and Italian university students. The present results highlight a need for further investigation of the correlates of ON across different cultural groups. Future research may screen individuals with ON to determine the comorbidity between ON and OCD symptomology to facilitate appropriate treatment choices. Level of evidence Level V, Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

The objectives of the present study were to (1) evaluate prevalence of orthorexia nervosa (ON) in university students in Spain and Poland, (2) assess differences in ON and eating disorder (ED) pathology in both samples and (3) examine the relationship between ON and ED symptoms among Spanish and Polish university students. Eight hundred and sixty university students participated in the present study (Mage = 21.17 ± 3.38; MBMI = 22.57 ± 3.76). The Spanish and Polish samples comprised 485 and 375 students, respectively. The Düsseldorf Orthorexia Scale and the Eating Disorder Inventory were used in the present study. ON prevalence rates of 2.3% and 2.9%, respectively, are found in the Spanish and Polish samples. Compared to Polish students, Spanish university students reported increased drive for thinness and lower body dissatisfaction, lower level of ineffectiveness and lower level of interpersonal distrust. ON was positively related to drive for thinness, bulimia, body dissatisfaction, perfectionism interoceptive awareness (in both Spanish and Polish students) and ineffectiveness (in Spanish students). Our findings suggest that ON significantly overlaps with ED symptoms, which is in line with recent studies. Longitudinal studies are needed to assess how ON develops in a sample of young adults and whether it develops in isolation of or in parallel with ED pathology.

Moderating Role

Hunting has a long history, and contentious recent past. We examined the relationship between aggression and hunting attitudes, investigating the moderating role of sex. Two studies are presented—a psychometric evaluation of a unidimensional instrument for assessing hunting attitudes, which was then administered to a sample of general population participants to assess the relationship between aggression and hunting attitudes. Finally, university students completed measures of hunting attitudes and instrumental/expressive aggression. Men were more instrumentally aggressive than women and were more supportive toward hunting. The relationship between instrumental (but not expressive) aggression and hunting attitudes was moderated by sex—men’s hunting endorsement increased with instrumental aggression, while women’s endorsement of hunting decreased with increasing instrumental aggression. Expressive aggression was not predictive of hunting attitudes.
