Morality in romantic relationships: The role of moral disengagement in relationship satisfaction, definitions of infidelity, and committed cheating

Abstract

Despite the moral condemnation of infidelity in romantic relationships, its prevalence remains widespread. This might be partly explained by moral disengagement (MD), the ability to decouple one's actions from internalized moral standards. While social influences are an inherent part of the conceptualization of MD, they have not been studied in romantic couples. We investigated connections between MD and relationship satisfaction, cheating definitions, and cheating in a sample of 236 dating and married couples. Partners' levels of MD were positively correlated. Actor‐Partner‐Interdependence Models (APIMs) revealed negative actor and partner effects of MD on relationship satisfaction. MD was not connected to which behaviors are seen as cheating, but there were positive actor and partner effects on committed self‐defined cheating. Additionally, individuals high in MD suspected their partners to cheat more. These results indicate a gap between moral beliefs and moral actions. Individuals high in MD do not necessarily deny cheating on their partner but rather choose not to follow their inner moral compass.
