Betrayals in Emerging Adulthood: A Developmental Perspective of Infidelity

Infidelity is associated with considerable distress and discord in dating relationships. The current mixed methods study examined both the written narratives and survey responses of 104 (59.6% women) emerging adults to investigate reasons for engaging in infidelity (i.e., sexual and emotional infidelity). Emerging adults’ reasons for engaging in infidelity were attributed primarily to their primary relationships and/or their romantic partners not fulfilling their needs for interdependence and thus feeling motivated to fulfill these needs elsewhere. Although the majority of participants provided independence and/or interdependence reasons for their infidelity, a large proportion of responses (40%) referenced alternative reasons. These responses included (a) the opportunity to become intimate with an infidelity partner while under the influence of alcohol, (b) attraction to an infidelity partner, and (c) the excitement and novelty that the infidelity experience provided. Those who reported engaging in infidelity because of unmet interdependence needs, and intimacy needs in particular, were more avoidantly attached than those who did not reference unmet interdependence needs. Those who reported engaging in infidelity because of unmet independence needs were more anxiously attached than those who did not reference unmet independence needs. Implications for the developmental importance of infidelity in terms of research and applied work are discussed.
