Objective: To review the genesis and current status of "best practices" thi
nking, its application in health promotion practice, and in generalizing re
search to alternate populations, places and times. Methods: A presbyopic ey
e is cast over the recent evolution of the concept of "best practices" from
medicine to public health. Results: Some discontinuities are found in the
migration of this concept from medicine, where it applies with some consist
ency to the relatively homogeneous physiology of the human species, to heal
th behavior where social, cultural, economic, and other heterogeneities mak
e the generalizability of any research more suspect. Conclusions: Health pr
omotion and other applications of health behavioral research need to replac
e "best practices" with "best processes."
