Answer:
True
Step-by-step explanation:
The "Stages of Change Model" is also known as "Transtheoretical Model."
According to this model, a person undergoes changes in behavior gradually and "not all at once." In order to undergo gradual change, the person needs to follow a simple process that needs an ample time for commitment. This process consists of 6 stages namely Precontemplation, Contemplation, Preparation, Action, Maintenance and Relapse.
Since making a behavior change is not easy at all, it becomes important to follow these stages. This will allow the person to stick to his resolutions and prevent temptations in the future.
Thus, this explains the answer.
