Possibly due to the relatively recent emergence of
the concept of health coaching, the reviewed literature
did not reveal a clear change in the concept over time.
This may be further explained by the small number of
articles pertaining to the concept that were published
prior to 2006 as compared with the past 5 years. One
exception to this was an increase in web-based health
coaching in recent years. Also noteworthy was a
recent increase in health coaching literature that
explored the theoretical foundations of the concept.
