Characteristics of those who participate in infidelity: The role of adult attachment, identity, and differentiation in extradyadic experiences

Jessica N Fish, Purdue University

Abstract

The present study examines the relationship between adult attachment style, differentiation, identity status, and infidelity. While there is a multitude of research highlighting personal and relational characteristics of those who participate in extradyadic relationships, previous research has shown contradictory and muddled findings. Previous research on infidelity has suggested conflicting ideas on the role of adult attachment and differentiation on infidelity, while there is nothing to explore the role of identity within infidelity. Results indicated that attachment anxiety and avoidance both showed significant relationships with infidelity in both bivariate and multivariate analysis. Differentiation also showed significant results at the bivariate level, where as fusion with others, a differentiation subconstruct, contributed significantly to the overall model in predating infidelity. Identity statuses' effect on infidelity was minimally supported and did no contribute to the overall model. Interestingly, transgenerational patterns of infidelity within the family of origin and the knowledge or a parental affair increased the chances of individuals participating in extradyadic relationships as well as a few demographic characteristics. Finally, clinical implications and areas of future research are discussed.
