The model or theory that suggests that behavior is shaped by one's intention to act or not act, and that intentions are shaped attitudes, subjective norms, and perceived behavioral control is <u>the theory of planned behavior.</u>
<u />
Explanation:
The theory of planned behavior seeks to explain any health behavior over which the individual has control. It believes that behavior is determined directly by a person's intention of performing it. In other words, a number of factors influence a person's decision when it comes to a certain behavior, such as pressure from family or society, the belief that changing that behavior will be easy or difficult, the belief in one's own capacity to do it etc.
