This study aims to explore whether orthorexia nervosa, like other eating disorders, is associated with difficulties identifying, describing, and regulating one's own emotions among a sample of Lebanese adults.
A cross-sectional study was conducted during October 2020, during the lockdown period imposed by the government for the COVID-19 pandemic. All participants above 18 years of age were allowed to participate in this study. A total of 787 Lebanese adults out of 920 (85.54%) completed an online survey including Arabic versions of the ORTO-R measure of orthorexia, the Toronto Alexithymia Scale, the Difficulty in Emotion Regulation Scale, and the Eating Attitudes Test.
After making sure that all norms are verified, hierarchical linear regressions were conducted to evaluate the association between disordered eating attitudes (EAT scores) and ON (model 1), and after controlling for difficulties in emotion regulation (DERS score) (model 2). Model 1 accounted for 15.1% of the variance of ON (adj. R = 0.151, F(1, 786) = 140.06, p < 0.001) and showed that higher levels of disordered eating (higher EAT scores) (β = 0.15) were significantly associated with more ON tendencies and behaviors. When adding the DERS total score to the model, Model 2 was a much better fit with 17.7% of the variance of ON (adj. R = 0.177, F(2, 786) = 84.44, p < 0.001), with higher levels of emotion dysregulation (higher DERS scores) (β = 0.06) and more disordered eating attitudes (higher EAT scores) (β = 0.13) were associated with higher levels of ON (Table 5).
The present research suggests that people with high ON tendencies experience troubles recognizing, regulating, and describing their emotions, similarly to other disordered eating.
本研究旨在探索神经厌食症是否与其他饮食障碍一样，与黎巴嫩成年人样本中识别、描述和调节自身情绪的困难有关。
在 2020 年 10 月期间进行了一项横断面研究，当时正值政府为应对 COVID-19 大流行而实施封锁期间。所有年龄在 18 岁以上的参与者都被允许参加这项研究。共有 787 名黎巴嫩成年人（85.54%）完成了一项在线调查，其中包括神经厌食症的 ORTO-R 量表、多伦多述情障碍量表、情绪调节困难量表和饮食态度量表的阿拉伯语版本。
在确保所有规范都得到验证后，进行了分层线性回归，以评估饮食障碍态度（EAT 评分）与 ON（模型 1）之间的关联，以及在控制情绪调节困难（DERS 评分）（模型 2）之后。模型 1解释了 ON（调整后的 R=0.151，F（1，786）=140.06，p<0.001）的 15.1%的方差，结果表明，更高水平的饮食障碍（更高的 EAT 评分）（β=0.15）与更高的 ON 倾向和行为显著相关。当将 DERS 总分添加到模型中时，模型 2与 ON（调整后的 R=0.177，F（2，786）=84.44，p<0.001）的方差拟合度更好，情绪失调程度更高（更高的 DERS 评分）（β=0.06）和更高的饮食障碍态度（更高的 EAT 评分）（β=0.13）与更高的 ON 水平相关（表 5）。
本研究表明，具有高 ON 倾向的人在识别、调节和描述情绪方面存在困难，这与其他饮食障碍类似。
