With university mission statements focused on preparing emerging adult students for globally inclusive professional careers, moral and leadership development has become a central focus of many colleges and universities (Bass, 1991; Binghamton University, 2016; Zimmerman-Oster & Burkhardt, 1999). Colleges and universities utilize interactions and experiences to broaden an emerging adult's awareness of an individual's role within a community, understanding of self, responsibility towards socially beneficial actions, discovery of personal and social values, and future life path (Burkhardt & Zimmerman-Oster, 1999; Rest, 1988). A dynamic college environment - with frequent interactions and experiences - provides developmental opportunities for emerging adult students to broaden awareness and inspire reflection towards a more advanced level of moral reasoning and leadership (Astin, 1993; Rest, Narvaez, Bebeau, & Thoma, 1999a). The athletic environment may provide emerging adult student-athletes with unique opportunities for frequent interactions and feedback from peers, adults, and the community. Members of an intercollegiate athletics team learn to collaborate and subscribe to group goals, which may support the development of emerging adult student-athlete transformational leadership practices. Therefore, an exploration of the moral judgment, community engagement, and transformational leadership behaviors of emerging adult student-athletes may offer an understanding of the unique developmental environment that exists in intercollegiate athletics. To understand the influence of opportunities and interactions within a university intercollegiate athletic department, a sample of emerging adult student-athletes were recruited to complete three survey instruments exploring moral judgment (Defining Issues Test; DIT-2), transformational leadership practices (Student Leadership Practices Inventory; S-LPI), and the influence of community engagement behaviors (National Survey of Student Engagement; NSSE). This research examines four hypotheses: the relationship between moral judgment and community engagement of emerging adult student-athletes, the relationship between community engagement and transformational leadership practices, the mediated relationship where community engagement serves to mediate the relationship between moral judgment and transformational leadership, and finally, the moderating effect of gender on the aforementioned mediated relationship. Findings aim to inform athletic higher education staff and administrators to enhance opportunities for student-athlete development of moral judgment and transformational leadership behaviors.
