概要	The Theory of Planned Behavior (TPB) is a psychological framework developed by Icek Ajzen in 1991 to predict and understand deliberate human behavior. The TPB questionnaire measures four core constructs that explain why people intend to perform (or not perform) a specific behavior: attitudes toward the behavior, subjective norms, perceived behavioral control, and behavioral intention. This measure is widely used in health behavior research, particularly for understanding health promotion, disease prevention, and lifestyle change initiatives.	The Health Belief Model (HBM) is a foundational psychological framework developed by Marshall Rosenstock in 1966 to predict and explain preventive health behavior. Based on the central premise that people take health action to avoid illness when they perceive susceptibility to a health threat and believe that taking action will reduce that threat at an acceptable cost, the HBM measures four core constructs: Perceived Susceptibility, Perceived Severity, Perceived Benefits, and Perceived Barriers. The model also incorporates 'Cues to Action' (external triggers) and 'Self-Efficacy' (added later). HBM is extensively used in research on disease prevention, health screening uptake, medication adherence, and vaccine acceptance.
