Mediator Roles of Perfectionism and Self-Critical Rumination in the Relationship Between Perceived Maternal Rejection and Orthorexia: A Model Testing in a Female Sample

Orthorexia nervosa (ON) refers to a pathological obsession with healthy eating characterized by a restrictive diet, ritualized eating patterns, and strict avoidance of foods believed to be unhealthy or unclean. On the other hand, healthy orthorexia (HO) is defined as an interest in healthy eating and a tendency to eat healthy foods. This study aimed to investigate the relationships between the ON, HO, maternal rejection, perfectionism, self-critical rumination, and body attitude in the women sample. 445 female students from diverse universities in Turkey was attended to our study. Participants completed questionnaires regarding ON and HO, body attitude, maternal rejection, perfectionism, and self-critical rumination. The results showed that negative body attitudes could not predict both HO (B=-.008, SE=.039, p=.791) and ON (B=.008, SE=.032, p=.835). However, perfectionism and self-critical rumination had mediator roles in the relationship between ON and HO with maternal rejection, despite this relationship was positive for ON (B = .014, Boot SE = .007, 95% Boot CI [.003, .029]), but negative for HO (B = -.023, Boot SE = .010, 95% Boot CI [-.042, -.008]). Not a negative body attitude, but maternal rejection, perfectionism, and self-critical rumination played roles in developing orthorexic tendencies.
