The purpose of this study was to identify and examine the role of dispositional characteristics in effective mentoring relationships. A learning and development framework was incorporated to examine the relationships of protégé and mentor characteristics, mentoring provided, and developmental mentoring outcomes. First, relationships between individual characteristics and mentoring provided were examined. Second, relationships between individual characteristics and partner developmental outcomes were examined. Third, mentoring provided was examined as a mediator of individual characteristics and partner developmental outcomes. The final sample consisted of 93 protégé-mentor pairs. Protégés and mentors were asked to complete an online survey measuring learning goal orientation, locus of control, self-efficacy for development, mentoring received/mentoring provided, and multiple assessments of relationship effectiveness. In general, the hypotheses were not supported, but supplemental analyses provided support for the importance of examining individual characteristics. Key findings contribute to the mentoring literature by illustrating the role of learning goal orientation and self-efficacy for development in effective mentoring relationships. Future research should investigate additional underlying mechanisms that further explain the mentorship learning exchange processes.
