Step-by-step explanation:
The model of behavioral change that focuses on the individual's decision making and states that an individual progresses through a sequence of six stages as they make a change in behavior is called the stages of change model or the transtheoretical model.
This model was developed by psychologist James O. Prochaska and his colleagues in the late 1970s. It recognizes that behavior change is a process that takes time and involves different stages, including precontemplation, contemplation, preparation, action, maintenance, and termination.
For example, let's say someone wants to quit smoking. Using the stages of change model, they would first become aware of the need to quit (precontemplation), then start thinking about the benefits and barriers of quitting (contemplation), prepare a quit plan (preparation), take action by actually quitting (action), continue to maintain the change and prevent relapse (maintenance), and eventually reach a point where they no longer have any desire or temptation to smoke (termination).
