Abstract
A previous unpublished study found positive associations between jealousy (cognitive, emotional, behavioural) and the Dark Triad (narcissism, Machiavellianism, psychopathy) (Raheb, Atkinson, Chin, Vernon, submitted). The present study investigates whether self-esteem and entitlement mediate these positive relationships. To test this question, 453 participants (311 females, 140 males, 2 other) between the age of 17 to 81 years (M = 33.19, SD = 10.32) completed the Multidimensional Jealousy Scale, the Short-D3, the Psychological Entitlement Scale, and the Rosenberg Self-Esteem Scale. One model showed significant mediation: higher psychopathy was related to higher cognitive jealousy, and this relationship was significantly mediated by lower self-esteem. Therefore, individuals higher in psychopathy may be especially prone to cognitive jealousy if they have low self-esteem. These findings identify dimensions of the Dark Triad and other personality traits that influence the propensity to experience types of jealousy.
