Practicing What You Preach: Infidelity Attitudes as a Predictor of Fidelity

The current studies used the Perceptions of Dating Infidelity Scale (PDIS), which identifies attitudes toward three types of behaviors indicative of cheating: Ambiguous, Deceptive, and Explicit behaviors, to predict actual infidelity behaviors. Participants reported their attitude toward these behaviors and then reported their willingness to engage in these behaviors with a hypothetical target (Study 1) and reported actually engaging in these behaviors over the course of one month (Study 2). Study 1 showed that attitudes for Ambiguous and Deceptive behaviors significantly predict a willingness to engage in these behaviors with a hypothetical target. Study 2 showed that attitudes toward Ambiguous behaviors significantly predict actual engagement in Ambiguous behaviors during the course of one month.
