Abstract
PurposePast research has revealed a link between orthorexia nervosa (ON) and relationship dissatisfaction, which has in turn been found to be correlated with the Dark Triad traits. The current study investigated the association ON has with seeking out relationships and with relationship satisfaction, while also assessing a potential moderating effect of the Dark Triad.MethodRecruited from Reddit forums, 788 adults completed an online survey with scales assessing ON symptomology, relationship satisfaction, relationship seeking, and the Dark Triad. ResultsGreater ON symptomatology was associated with greater levels of all aspects of the Dark Triad (Machiavellianism, narcissism, and psychopathy), as well as with lower levels of relationship satisfaction (among those in committed romantic relationships) and a lower likelihood of seeking new romantic relationships (among single participants). A regression analysis revealed that the Dark Triad moderated the association between ON and relationship satisfaction, whereby this association was not significant at high levels of the Dark Triad. ConclusionThe current research highlights that at low and medium levels of the Dark Triad, greater ON symptomology is associated with lower levels of satisfaction in romantic relationships.
