Despite repeated efforts to encourage health professionals to conduct practice-based research, including qualitative research, few practitioners have become active researchers. Mentoring, networking, and hands-on experience have been identified as potential approaches for changing this situation. In this article, the authors describe how they implemented a research mentoring/training component in a national study exploring Canadian dietitians' attitudes and practices with regard to obesity and weight management. They discuss the successes and challenges experienced by mentors and trainees, and provide recommendations for future initiatives to enhance capacity for qualitative, practice-based research among health care practitioners.
