We have added this information on p. 7 in the Procedure section. It reads: Approval from the university Human Research Ethics Committee was obtained prior to data collection. At Time 1 (T1), participants were approached at a university campus in Australia in the week before classes commenced (i.e., during orientation week) and asked to participate in a study "About You and Your Relationships." The front cover of the survey described the questions as focused on personal sexual and romantic experiences, and stressed the confidential nature of the survey.
A sense of entitlement to sexual partner pleasure increased significantly over the year of the study, whereas, on average, there was no change in self-efficacy over time.
