To achieve many outcomes promoted by student affairs educators, students need the internal capacity to author their knowledge, identities, and relationships. This study examined the link between students' entering self-authorship capacity and their experiences and outcomes in their first and fourth years. Findings from 214 participants indicate that self-authorship capacity is positively and significantly associated with subsequent academic challenge, diversity experiences, and faculty/staff interactions, which then predict increased psychological well-being, leadership skills, and intercultural competence.
