We describe interventionist training procedures for a pilot intervention study that tested the effects of a nurse-delivered Motivational Interviewing (MI) intervention on diabetes self-care among adults diagnosed with type 2 diabetes mellitus. It reports on findings from MI fidelity assessments. Training consisted of didactic workshops plus practicum. Fidelity of MI was assessed using the MI Treatment Integrity (MITI) Scale. Fidelity assessments were conducted on 18 (25%) audiotaped MI sessions, which were randomly selected from a total of 72 sessions with 26 participants. Scores of the MITI were in the proficient and competent range. Results suggest that training strategies were sufficient to promote satisfactory interventionist fidelity to MI. © 2012 Wiley Periodicals, Inc. Res Nurs Health 35:289–300, 2012
