While numerous studies have emphasized more situational factors related to cheating, hooking up, and attention to romantic alternatives (e.g., alcohol use, need fulfillment, opportunity), the present findings support Finkel el al.'s (2012) argument for greater attentiveness to personal factors intrinsic to the individual that may influence the incidence of such behaviors. Personal factors (e.g., avoidant attachment, selfishness, and maximizing) were found to be significantly related to cheating, hooking up, and attention to romantic alternatives, explaining as much as 40% of the variance in these behaviors.
