সারসংক্ষেপ	The Barriers to Physical Activity Questionnaire (BPA) is a scale designed to identify and measure perceived obstacles to exercise engagement. Rooted in the Health Belief Model and Health Promotion Model, the BPA assesses multiple categories of barriers—time constraints, lack of motivation, physical discomfort, cost, lack of facilities, social/family factors, and weather—that individuals perceive as preventing or limiting physical activity. Understanding which barriers are most salient for a given individual or population enables targeted intervention design, such as time management coaching, facility access solutions, or social support programs. The BPA is widely used in primary care, community health, occupational health, and exercise research to segment populations and tailor physical activity prescriptions.	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.
