Correct Response: D. Behavioral change is largely dependent on the motivation to change, as illustrated by the examples. People who believe that they are susceptible to a lifestyle-related health problem will be motivated to take preventive action. This concept is central to the health belief model. In contrast, people who believe that they are immune to lifestyle-related health problems or who enjoy unhealthy behavior will not be motivated to adopt new habits. These examples illustrate several ways that personal beliefs and attitudes can influence health practices. The role of significant others (A), choosing a behavioral-change technique that aligns with one's values (B), and the acceptance of external evidence (C) are all generally positive forces that increase motivation. Therefore, these options do not illustrate the two examples that describe resistance to change.
