This article reviews recent evidence documenting the efficacy of primary pr
evention approaches in mental health and calls attention to several differe
nt ways in which that concept has been used: a) the current, widely espouse
d, risk detection-disorder prevention. model, pivoting around initial ident
ification of risk factors for adverse psychological outcomes; and b) a more
inclusive, challenging, life-span-oriented wellness enhancement model, bas
ed on the view that psychological wellness per se may provide significant p
rotection against the likelihood of major psychological disorder. The autho
r considers points of overlap between these two models as well as important
differences in their underlying conceptualizations, defining strategies, a
nd contexts of support. The article depicts a disorder prevention approach
as one aspect of a more comprehensive, life-span oriented wellness enhancem
ent approach, and argues for more central roles and support for both models
within a changing overall mental health matrix. (C) 2000 John Wiley & Sons
