Three of these approaches are shared decision making, when there is more than one reasonable choice, motivational interviewing, principally for behaviour change and therapeutic education, a pedagogical approach helping patients develop skills so that they may have a better management of their chronic illness. This article presents an overview of the commonalities and the differences between these approaches, often considered separately, nevertheless they are complementary and in practice, using elements of all three during a consultation could improve preventative care.
