The role of eating disorders features, psychopathology, and defense mechanisms in the comprehension of orthorexic tendencies

Purpose Recent studies pointed out the importance to distinguish orthorexia nervosa (ON) from non-problematic forms of interest with healthy eating. This distinction needs to be further explored since it may favor a better comprehension of the relationship between orthorexic behaviors and psychopathology and lead to an improved understanding of the psychologi- cal processes implicated in ON. Therefore, the aim of the current study was to investigate the associations between ON and the core features of eating disorders (EDs), psychopathological symptoms and defense mechanisms, by differentiating three groups of individuals: an ON symptoms group, a healthy-eating control group, and a normal-eating control group. Methods Collegestudents(n=270,Mage=21.57,SD=2.16)wererecruitedfromPalermo’sUniversity,inthesouthofItaly, and were assigned to three groups: 52 in the ON symptoms group, 157 in the healthy-eating control group and 61 in the normal-eating control group. Participants completed four questionnaires assessing ON (EHQ-21), eating psychopathology (EDI-3), psychopathological symptoms (BSI) and defense mechanisms (DSQ-40). Results Compared to the control groups, the ON symptoms group reported greater EDs’ features, higher psychopathologi- cal symptoms and greater employment of different neurotic and immature defense mechanisms. No differences were found between groups with regard to obsessive–compulsive symptoms. Conclusion Our findings support the notion that ON behaviors should be carefully distinguished from non-problematic forms of interest with healthy eating. Indeed, results suggest that ON individuals are characterized by similar clinical features and defensive functioning as those observed in traditional EDs, indicating the importance of deepening our understanding of the relationship between these conditions.
