The Brazilian version of the DOS for the detection of orthorexia nervosa: transcultural adaptation and validation among dietitians and Nutrition college students

A systematic review and meta‐analysis of the relationship between obsessive‐compulsive symptoms and symptoms of proposed orthorexia nervosa: The contribution of assessments

“…(2021) and Yazkan and Uğurlu (2022), found a large correlation between ON and OC symptoms ( r = 0.53, p < 0.001 and r = 0.74, p = 0.024 respectively) and 14 studies found moderate correlations (Albery et al., 2022; Barrada & Roncero, 2018; Bóna et al., 2019; Chace & Kluck, 2021; Çiçekoğlu & Tunçay, 2018; Koven & Senbonmatsu, 2013; Mitrofanova et al., 2021; Moller et al., 2019; Novara, Maggio et al., 2021; Novara, Pardini, et al., 2021; Poyraz et al., 2015; Rogowska et al., 2021a, 2021b; Zhou et al., 2020). Seventeen studies found at least one small but significant ON/OC relationship (Arusoğlu et al., 2008; Brytek‐Matera et al., 2017, 2020, 2022; Bundros et al., 2016; Cerolini et al., 2021; Costa & Hardan‐Khalil, 2019; Demir & Bayram, 2022; Hallit et al., 2022; Hayes et al., 2017; Levin et al., 2023; Novara et al., 2022; Novara, Maggio, et al., 2021; Souza et al., 2022; Strahler et al., 2018; Yakin et al., 2021a, 2021b; Zickgraf et al., 2019), and seven found no significant ON/OC relationship (Ambwani et al., 2019; Andreas et al., 2018; Asil & Sürücüoğlu, 2015; Dabal, 2020; Lasson & Raynal, 2021; Vaccari et al., 2021; Yilmaz et al., 2020).…”

“…Six studies investigated ON and OC symptom relationships using the DOS. All except one sample (Lasson et al., 2021) reported at least one statistically significant, small to moderate relationship (Brytek‐Matera et al., 2020; Cerolini et al., 2021; Hallit et al., 2022; Souza et al., 2022; Strahler et al., 2018). DOS Cronbach's alpha coefficients ranged from 0.66 to 0.90.…”

What Factors Impact the Disordered Eating of Nutrition Students: From a Socio-Cultural Perspective

“…A Brazilian study substantiates this description. Students with a high level of healthy food preoccupation are likely to exhibit pathological refusal to high-calorie foods, as well as possess high EAT-26 measurement scores, a validated dieting subscale [13]. On that account, the pathology associated with healthy food preoccupation is addressed in the context of disordered eating, despite its good starting point.…”

“…A study reports that social desirability may lead to biased self-reports on vegetable intake in females enrolled in a nutrition program [33], in other words, participants showed an attempt to present themselves closer to the standard of healthy and thin to acquire more recognition. In addition, the nutrition students' psychological inflexibility [13] exhibited by the strength of thinness belief was identified to be especially problematic regarding the situation of thin-ideal internalization. Participants of the past study were found to be preoccupied with negative self-cognitions and idealized thinness if they score high on the psychological inflexibility subscale.…”
