Changing high risk behaviours involves progress through six stages of
change: precontemplation, contemplation, preparation, action, maintena
nce and termination. Stage-matched programs for cardiovascular disease
prevention can produce much higher participation rates than tradition
al action-oriented programs (80 to 85% versus 1 to 5%). The amount of
success following intervention is directly related to the state of cha
nge participants are in before intervention. Helping people progress t
hrough the stages involves matching particular processes and principle
s of change to particular stages of change.
