OBJECTIVE: 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.
METHODS: 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.
RESULTS: 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. R2 = 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. R2 = 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).
CONCLUSION: The present research suggests that people with high ON tendencies experience troubles recognizing, regulating, and describing their emotions, similarly to other disordered eating.
LEVEL OF EVIDENCE: 5.
