[Impact of training on Motivational Interviewing (MI) for Family Physicians: Design and assessment of a Training Program (MOTIVA)].

Aim: To develop a training program in Motivational Interviewing for Family Physicians and assess the impact.

Study Design: Multicenter, double blind and randomized clinical essay, with 2arms, Experimental (EG) and Control (CG) of Family Physicians with a follow up of 12 months.

Location: 32 Primary Healthcare Centers.

Sample Description: 54 physicians (CG=28, EG=26).

Interventions: Training Program MOTIVA in ME with an initial presential course (16h), followed by online activities during 12months, and presential meetings (Problem BasedInterviewing with expert feedback).

Main Measurements: Communicative skills in MI were assessed based on video-recordings (VR) with the EVEM 2.0 scale by peer reviewers. 236 VR with standardized patients and 96 VR with real patients.

Results: Average results in EVEM scale (up to 56 points) at the beginning of the study were EG=21.27 (CI 95% 15.8-26.7) and CG=20.23 (CI95% 16.4-23.9) with no differences between both groups (P=.79). After the training, EG punctuation increased by 13.89 points (P<.001), average 35.16 (CI 95% 29.8-40.6). Real patients' VR in EG over a 12 month period keep their MI skills with an average of 36.9 points (CI 95% 30.3-43.6) versus CG 15.9 points (CI 95% 9.8-22.0). Once ended the MOTIVA Training Program, the EG maintains the acquired skills: final average EG=37.6 (CI 95% 33.2-41.1) versus CG=24.3 (CI95% 19.0-29.2) (P<.001).

Conclusions: The MOTIVA Training Program improves Motivational Interviewing skills, significatively improving after a presential course and sequential keep-alive activities. The effectiveness of the Program has been proven in the Third and Fourth steps of Miller's Pyramid.
