What is an example of a barrier to changing unhealthy behaviors like smoking or overeating?

1. Perceived susceptibility

2. Perceived severity

3. Perceived self-efficacy

4. Perceived response efficacy

The correct answer is: Perceived self-efficacy

The concept of perceived self-efficacy refers to an individual's belief in their ability to successfully execute a behavior needed to produce specific performance attainments. High self-efficacy can empower individuals to initiate and maintain changes in their behavior, such as quitting smoking or adopting healthier eating habits. Conversely, low self-efficacy may serve as a barrier, making individuals doubt their capabilities and leading them to feel overwhelmed by the challenges associated with changing their behaviors. When individuals lack confidence in their ability to change—such as believing that they cannot resist cravings for cigarettes or unhealthy foods—they are less likely to take action toward modifying those unhealthy behaviors. Therefore, perceived self-efficacy is a crucial factor that influences one’s motivation and willingness to engage in efforts to change unhealthy habits.
