Insufficient physical activity among adolescents is a major global public health concern, and schools are considered key venues for promoting physical activity. Teachers play a crucial role in the implementation of policies. This study adapted and validated the COM-PASS scale, based on the COM-B model, to assess its reliability and validity in the Chinese context.
This study validates the appropriateness of the COM-PASS scale based on the COM-B model, assessing its reliability and validity within the Chinese cultural context. A three-phase design was employed: (1) A Delphi method involving three rounds of surveys with 15 experts to refine the questionnaire's relevance and validity; (2) Cognitive interviews with 10 primary and secondary school teachers to evaluate item comprehensibility; (3) Confirmatory factor analysis of 4,033 questionnaires across China's seven major administrative regions to verify structural validity and internal consistency.
The CFA results showed that the three-factor model fit well (χ = 3179.436, df = 518, CFI = 0.964, TLI = 0.956, RMSEA = 0.036), with factor loadings for all items exceeding 0.750. The Cronbach's α coefficients for the three dimensions were 0.957, 0.947, and 0.965, respectively. Path coefficient tests indicated strong explanatory power of the latent variables on the observed variables (standardized path coefficients ranged from 0.781 to 0.951). Cross-group validation demonstrated the scale's stability and applicability across different administrative regions in China.
The Chinese version of the COM-PASS scale has shown good reliability and validity among the population of Chinese primary and secondary school teachers, and it can effectively assess main factors affecting the development of school physical education activities. The results provide a targeted scientific basis for optimizing school physical education policies, addressing regional resource differences, and teacher training strategies. The scale demonstrates strong cultural applicability and provides practical guidance for enhancing the 'Double Reduction' policy and advancing school-based physical education activities across China.
青少年身体活动不足是一个重大的全球公共卫生问题，学校被视为促进身体活动的关键场所。教师在政策实施中起着至关重要的作用。本研究基于COM - B模型对COM - PASS量表进行了改编和验证，以评估其在中国背景下的信效度。
本研究基于COM - B模型验证COM - PASS量表的适用性，在中国文化背景下评估其信效度。采用了三阶段设计：（1）德尔菲法，对15名专家进行三轮调查，以完善问卷的相关性和效度；（2）对10名中小学教师进行认知访谈，以评估项目的可理解性；（3）对中国七个主要行政区的4033份问卷进行验证性因素分析，以验证结构效度和内部一致性。
验证性因素分析结果表明，三因素模型拟合良好（χ = 3179.436，df = 518，CFI = 0.964，TLI = 0.956，RMSEA = 0.036），所有项目的因子载荷均超过0.750。三个维度的克朗巴哈α系数分别为0.957、0.947和0.965。路径系数检验表明，潜在变量对观测变量具有很强的解释力（标准化路径系数范围为0.781至0.951）。跨组验证表明该量表在中国不同行政区具有稳定性和适用性。
中文版COM - PASS量表在中国中小学教师群体中显示出良好的信效度，能够有效评估影响学校体育活动开展的主要因素。研究结果为优化学校体育政策、应对区域资源差异和教师培训策略提供了有针对性的科学依据。该量表具有很强的文化适用性，为加强“双减”政策和推进全国范围内的校本体育活动提供了实践指导。
