背景：选择最适合心理测量的自我报告工具来测量特定的身体活动结构对于研究人员、公共卫生从业者和临床医生来说一直是一个挑战。缺乏合理的黄金标准衡量标准以及对既定和不断发展的术语的使用不一致导致了这些挑战。自我报告措施和得出的总结估计质量的变化可能归因于缺乏身体活动的标准化概念框架。目标：提出一个概念框架，将身体活动视为一种复杂的多维行为，区分人类运动的行为和生理结构。流程：概念框架的制定可以为标准化定义、指导自我报告措施的设计和开发以及在工具选择过程中提供一致性提供基础。结论：根据我们提出的身体活动概念框架，我们建议将身体活动更明确地定义为涉及人体运动的行为，从而产生生理属性，包括增加能量消耗和改善身体健康。利用所提出的概念框架可以带来更好的仪器选择以及用于评估研究和公共卫生实践中身体活动和久坐行为的方法的一致性。
Context: The selection of the most psychometrically appropriate self-report tool(s) to measure specific physical activity constructs has been a challenge for researchers, public health practitioners, and clinicians, alike. The lack of a reasonable gold standard measure and inconsistent use of established and evolving terminology have contributed to these challenges. The variation of self-report measures and quality of the derived summary estimates could be attributed to the absence of a standardized conceptual framework for physical activity. Objective: To present a conceptual framework for physical activity as a complex and multidimensional behavior that differentiates behavioral and physiological constructs of human movement. Process: The development of a conceptual framework can provide the basic foundation from which to standardize definitions, guide design and development of self-report measures, and provide consistency during instrument selection. Conclusions: Based on our proposed conceptual framework for physical activity, we suggest that physical activity is more clearly defined as the behavior that involves human movement, resulting in physiological attributes including increased energy expenditure and improved physical fitness. Utilization of the proposed conceptual framework can result in better instrument choices and consistency in methods used to assess physical activity and sedentary behaviors across research and public health practice.
