P.3.b.037 - Cortical thickness, cortical surface area and subcortical volumes in schizophrenia and bipolar disorder patients with cannabis use

Abstract

Romantic relationship infidelity jeopardizes the romantic partner's mental health and the relationship. Personality differences may predispose individuals to infidelity. According to life history strategy, people with higher Dark Triad of personality are more likely to commit infidelity. In this study, 52 men and 88 women aged from 18 to 40 completed a questionnaire in Malaysia. Partial least square path modeling revealed that intentions towards infidelity have significant relationships with Machiavellianism and psychopathy, but non-significant relationship with narcissism. In addition, partial least square multi-group analysis revealed that relationship experiences moderate the association between narcissism and intentions towards infidelity, as well as the relationship between psychopathy and intentions towards infidelity, but did not moderate the relationship between Machiavellianism and infidelity intentions. This study raises opportunities for future research to refine and elaborate the links between dark personalities and adverse relationship outcomes. Findings and future directions are outlined taking an evolutionary psychological approach.
