The Transtheoretical Model was developed by Prochaska and
DiClemente in late 1970 in order to bring about an intentional
behavioral change such as quitting of smoking or overeating.
According to this model, the change in the habitual behavior occurs
through a cyclic process. According to this model the individual
passes through six stages of change. They are as follows:
- Precontemplation: In this stage, the individual is unaware of
the problems involved in a habitual behavior and does not intend to
make any change in the near future. As far as overeating is
concerned, while enjoying tasty foods especially junk food, most of
the people are unaware of the problems of overeating.
- Contemplation: In this stage an individual is little more aware
of the problems of the behavior and study the pros and cones. In
this stage also he is not determined to change the behavior.
- Preparation: In this stage the individual may take action to
stop the behavior within the next 30 days. The person is well aware
that by stopping the behavior he can lead a healthier life.
- Action: At this stage the individual may modify their behavior
or practice more healthy habits. For example, a person with over
eating behavior may confine his foods to those prepared at home and
also start exercising to reduce the problems such as overweight
which was result of over eating.
- Maintenance: At this stage the individual continue to work on
the behavioral changes and try even harder to stick on to newly
developed healthy habits.
- Termination: This is the last stage in which the individual
experience no more desire for over eating. Some people who decide
to take up a vegetarian diet to reduce over eating may find lesser
craving for meat products at this stage. But in most cases, this
stage is not reached and the individual continues to be in
maintenance stage.
Thus it can be seen that a habitual
behavior which is detrimental to the health of a person can be
changed through systematic approach through six stages as per
Transtheoretical model.
