Which of the following knowledge components of health education provides an individual the skills necessary to engage in a desired healthy behavior?

A. Ecological framework knowledge: This knowledge involves understanding how social, environmental, and policy-level factors influence health behaviors. While it provides context for health interventions, it does not directly equip an individual with the practical skills to perform a specific health behavior. B. Knowledge of underlying principles: This refers to understanding the scientific or theoretical rationale behind a health concept, such as knowing why hypertension develops from excessive sodium intake. It supports informed decision-making but does not teach the individual the actionable steps to carry out the behavior. C. How-to knowledge: This is the practical, procedural knowledge that allows an individual to perform a specific behavior, such as properly measuring blood pressure at home, performing wound care, or using an inhaler correctly. It directly translates into skill acquisition and behavior execution, bridging understanding with action. D. Awareness knowledge: Awareness knowledge refers to recognizing the existence of a health issue or risk, such as knowing that smoking increases lung cancer risk. While essential for motivation, it does not provide the technical skills needed to engage in preventive or therapeutic behaviors.
