Abstract
OBJECTIVES: To explore the possible moderating relation between impulsive behavior and maladaptive personality traits in regards to orthorexia nervosa (ON). METHODS: This cross-sectional study was conducted between July and December 2019 and recruited 519 Lebanese adults from seven community pharmacies randomly selected from a list provided by the Lebanese Order of Pharmacists. The Teruel Orthorexia Scale (TOS) was employed to assess orthorexic eating tendencies, the I-8 measured impulsivity and the Personality Inventory for DSM-5 (PID) evaluated maladaptive personality traits. RESULTS: Our results showed that, for I-8 subscales, only higher perseverance (B = 0.31) was significantly associated with higher ON. In regard to PID-5 subscales, only higher negative affect (B = - 0.34) was significantly associated with lower ON. Furthermore, significant interactions were found between personality traits and impulsivity to predict TOS-ON. CONCLUSION: The current results show that female gender, maladaptive personality traits and impulsivity present contributing factors regarding orthorexic eating. Certain impulsivity dimensions were confirmed to interact with personality traits in the prediction of orthorexic eating thereby highlighting possible risk factors and psychopathological mechanisms. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.
