Mentorship in academic medicine in the United States and Europe has been recognized as an effective system for increasing a mentee's research productivity, career success, and ability to obtain research grants. Therefore, to promote mentoring programs in Japanese academic medicine, it is important to investigate factors that facilitate or interfere with mentoring.
1)We interviewed 12 physicians who have performed clinical research under existing mentoring programs in Japan and asked them about factors that, in their experience, had facilitated or interfered with mentoring.
2)We qualitatively analyzed transcripts of interviews to identify these factors.
3)Factors identified as facilitating mentoring were: appropriate evaluation of a mentee's research skill, knowledge of a mentee's career goals, mutual communication between mentor and mentee, and the presence of senior researchers close to a mentee.
4)Factors identified as interfering with mentoring were: the busyness of a mentor, a mentee's concerns about giving offense by consulting the mentor about trivial matters, and the hierarchically organized social relationship in which the mentor is superior and the mentee is inferior.
5)Assessment of the mentoring process and education programs for mentors were expected to be necessary measures to promote mentoring programs.

  In Japan, few health care professionals have a basic understanding（core competency）of the design of clinical research and statistical analysis. We developed a blended distance–learning program comprising face–to–face lectures with e–learning for busy health care professionals who work in the clinical settings to achieve core competency in clinical research. The purpose of this study was to examine the educational effects of this program.
1）Four months after the end of the program, 64％ of the participants had started to conduct clinical research.
2）This program may increase the number of research colleagues that can discuss clinical research.
3）This program could enhance the confidence（self–efficacy）of health care professionals in clinical research.
