สรุป	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 Exercise Self-Efficacy Scale measures an individual's confidence in their ability to exercise regularly and maintain physical activity despite challenges. Grounded in Albert Bandura's Social Cognitive Theory, self-efficacy is the belief that one has the capability to execute a specific behavior and achieve desired outcomes. For exercise, self-efficacy encompasses confidence in overcoming barriers (time, fatigue, weather), maintaining consistency, and managing setbacks or relapse. Research consistently demonstrates that exercise self-efficacy is one of the strongest predictors of exercise adherence; individuals with high confidence are more likely to initiate exercise, persist through difficulties, and maintain activity over time. The scale is widely used in primary care, cardiac and pulmonary rehabilitation, weight management, diabetes care, and exercise research to assess readiness for behavior change and to evaluate interventions designed to boost confidence.
