How is "behavioral change" defined?

Behavioral change is best defined as the process of modifying habits or patterns of behavior to improve health. This definition encompasses a wide range of activities and strategies that individuals may engage in to promote better health outcomes. It includes changes in diet, physical activity levels, and other lifestyle choices that can significantly affect overall well-being.

Behavioral change is not merely about adopting new hobbies, as those activities may not have a direct impact on health improvements. Similarly, the decision to learn new skills does not inherently involve modifying existing behaviors or patterns, but rather focuses on acquiring knowledge or capabilities. Additionally, changes in one’s social circle may influence health indirectly but do not constitute a behavioral change in the sense of altering specific health-related habits or practices. Thus, the comprehensive nature of the process described in the correct answer captures the essence of what behavioral change entails in the context of health promotion.
