How can we persuade clinicians to adopt proven practices? Education, incent
ives, feedback, social marketing, and various other change strategies have
inconsistent and unpredictable effects. We propose a theoretical framework
that can provide a reliable basis for selecting effective change strategies
. We divide clinicians into 4 categories on the basis of their responses to
new information about the effectiveness of clinical strategies. We similar
ly divide the universe of practice change strategies into knowledge-oriente
d and behavior-oriented methods. We then show why specific combinations of
these strategies are likely to be consistently effective for each of the 4
categories of clinicians.
