To provide a foundation for mentoring, junior faculty participated in a mentor training workshop informed by the Mentoring Clinical and Translational Researchers curriculum. The goal was to develop skills and behaviors that engender more rewarding and inclusive mentoring practices. Attendees responded to baseline and follow-up surveys assessing perceived mentoring skills. Follow-up surveys included closed- and open-ended questions about the value and satisfaction of the training, and intended behavior changes. Junior faculty respondents (n = 39) reported significantly higher overall mentoring skills after the training (t = -2.6, p = 0.012) with a medium effect size (Cohen's D = 0.59). Domains with statistically significant improvement from baseline to follow-up included aligning mentor-mentee expectations and assessing understanding. Thirty-eighty (97%) found the training valuable, and 32 (82%) indicated they would change mentoring-related behaviors because of the training. Intended behavior changes described in open-ended responses aligned with mentoring skills assessed (e.g., aligning expectations). An additional competency domain of was also described. A mentor training workshop for junior faculty appeared to contribute to changes in mentoring skills and intended behaviors. Mentor training has the potential to enhance mentorship, which is critical to strengthening a diverse pipeline of clinical and translational science researchers.
