There might be a problem with this question, if you are only thinking of workshops! If you are thinking, for example, that you can go and to a workshop, say for a few days, and then you are trained, you could be disappointed. We see it more as a process of learning, where a variety of media and opportunities can enhance your skills. Workshops can be very useful indeed, but on their own, they have limited impact. I might add to this particular answer as the months unfold, because there are lots of creative and positive things one can do to get better at doing MI.

One very good starting point is the patient or client in front of you. His or her reactions to what you say on the topic of behaviour change is at the heart of MI. Your adjustments in the face of the person's often seemingly irrational talk about change is where the skilfulness comes in. Books and videos can help in understanding the principles and skills used in MI. Looking into your own practice, via a recording or with a supervisor can be enormously valuable.

The international Motivational Interviewing Network of Trainers (www.motivationalinterview.org) provide a list of trainers worldwide, all members of MINT.  However, this is not a certified programme, and there as yet is no formal code of practice or standards of practice adhered to by MINT members. MINT is run by volunteers.  They have issued the following statement about the trainers listed on their website:

The Motivational Interviewing Network of Trainers (MINT) is an international collective of trainers sharing an interest in improving the qualty and effectiveness of counseling and consultations given to clients about behavior change. MINT members are enrolled through participating in a formal training of trainers program and share an active private email listserv through which they consult with one another in order to improve the quality of their workshops and consultations.

Most MINT trainers share in the belief that ongoing on-site consultation is the best method to facilitate improvement in the practice of motivational interviewing and brief behavior consultations, and most MINT training is provided through private contracts of this nature. However, we recognize that off-site introductory and advanced workshops and coursework provide another useful forum for improving practice, and that, for many individuals, these represent an important source of learning. For these reasons, on this page we list trainings and conference presentations offered by MINT trainers that are open for registration to counseling and health professionals. The MINT does not "endorse" these trainings. We expect these these trainings to be high in quality, but have no current mechanism to monitor or evaluate the workshops or the trainers who provide them. So we offer here descriptive information to help website visitors determine if the offerings are likely to meet their needs and interests.
