Abstract：
UNASSIGNED: Adolescence represents a pivotal stage in the development of healthy behaviors, where establishing positive physical activity habits can have enduring effects on an individual\'s overall wellbeing. The ecological model highlights the influence of environmental factors on human behavior, with the family environment playing a significant role in shaping the physical activity habits of adolescents.
UNASSIGNED: The aim of this scale is to develop a reliable and effective tool, customized for the unique societal context of China, to assess how family factors influence the physical activity habits of Chinese adolescents. Participants were recruited through stratified cluster sampling from 24 secondary schools in six Chinese provinces between October and November 2021, resulting in 1,061 participants. Analysis was conducted on 1,004 valid questionnaires, divided into two samples. Sample 1, consisting of 502 students (248 males and 254 females; Mage = 15.5), underwent item analysis and exploratory factor analysis. Sample 2, comprising 502 students (267 males and 235 females; Mage = 16.5), underwent confirmatory factor analysis and internal consistency reliability analysis.
UNASSIGNED: Through exploratory factor analysis, we extracted three factors comprising 15 items: \"Family Environment Construction\" (4 items), \"Family Action Support\" (6 items), and \"Family Health Awareness\" (5 items). The Cronbach\'s alpha values for these factors ranged from 0.890 to 0.894. Confirmatory factor analysis confirmed a satisfactory model fit (CMIN/DF = 1.45, SRMR = 0.027, GFI = 0.991, TLI = 0.989, RMSEA = 0.03).
UNASSIGNED: The scale demonstrated strong internal consistency and test-retest reliability, confirming its effectiveness in empirical research. This study holds significant implications for enhancing the physical activity levels of adolescents, promoting their physical and mental wellbeing, enriching their developmental experiences, and contributing to their overall sense of happiness.

摘要：
■青春期是健康行为发展的关键阶段，建立积极的身体活动习惯可以对个人的整体福祉产生持久的影响。生态模型突出了环境因素对人类行为的影响，家庭环境在塑造青少年身体活动习惯方面发挥着重要作用。
■该量表的目的是开发一种可靠而有效的工具，为中国独特的社会环境定制，评估家庭因素如何影响中国青少年的体育锻炼习惯。在2021年10月至11月期间，通过分层整群抽样从中国六个省份的24所中学招募了参与者，导致1061名参与者。对1,004份有效问卷进行了分析，分成两个样本。样本1，由502名学生组成（248名男性和254名女性；法师=15.5），进行项目分析和探索性因素分析。样本2，包括502名学生(267名男性和235名女性；法师=16.5)，进行验证性因子分析和内部一致性信度分析。
■通过探索性因素分析，我们提取了三个因素，包括15个项目：“家庭环境建设”(4个项目)，“家庭行动支持”（6项），和“家庭健康意识”(5项)。这些因素的Cronbachα值范围为0.890至0.894。验证性因素分析证实了令人满意的模型拟合（CMIN/DF=1.45，SRMR=0.027，GFI=0.991，TLI=0.989，RMSEA=0.03）。
■量表显示出很强的内部一致性和重测可靠性，证实了其在实证研究中的有效性。这项研究对提高青少年的身体活动水平具有重要意义。促进他们的身心健康，丰富他们的发展经验，并为他们的整体幸福感做出贡献。
