This work analyzes inter-parental revenge after a breakup process, as it relates to the dark triad of personality, moral disengagement, and sex role ideology. Our objective was to test a predictive model for revenge based on these variables. Additionally, a scale to measure revenge among parents was developed. A sample of 384 participants who had minor children, had broken up their relationship, and had undergone or were undergoing problematic judicial procedures regarding their children completed a survey. They answered to measures of the dark triad of personality (Machiavellianism, narcissism, psychopathy); moral disengagement strategies; sex role ideology, and revenge. An instrument (the R scale), with adequate reliability and validity was developed to test revenge. Results show that revenge behaviors are perpetrated by 1 to 5% of participants. Revenge has three components: revenge through the child, revenge through economic manipulation, and revenge by cutting off communication. Results also show that for males, but not for females, sex role ideology mediates the relationship between the components of the dark triad, moral disengagement, and revenge. This paper aims at providing some insight for the protection of minors from manipulation by means of the Family Courts.
