【摘要】 目的：基于生态系统理论，开发一份适用于我国青少年体育家庭促进因素量表，并对其信度和效度进行验证。方法：利用区域抽样法，对华东、华中、华南、西南及西北地区的20名10至18岁青少年样本进行访谈。利用扎根理论对访谈资料进行三级编码，初步构建青少年体育家庭促进因素的结构维度，设计出30个初始题项。最后，对1371名青少年进行问卷测试，筛选有效问卷后，随机分为两组进行探索性和验证性因子分析。研究结果：探索性因子分析揭示量表包含行为习惯、父母体育支持、家庭运动价值观、资源投入四个维度，共13个题项。验证性因子分析证实了模型结构的有效性，各项拟合指标均满足接受标准(χ~2/df=2.490,GFI=0.962,CFI=0.981,IFI=0.981,AGFI=0.952,RMSEA=0.052)。此外，总量表及各维度α系数为0.832～0.922,折半信度为0.840～0.884,平均提取方差(AVE)为0.624～0.721,组合信度(CR)为0.838～0.963,且均达到显著性水平。研究结论：青少年体育家庭促进因素量表具有良好的信、效度。本研究为未来相关定量研究提供了一种有效测量工具。更多还原

【Abstract】 Drawing on ecological system theory, this study aims to create a scale suitable for assessing family-based factors promoting adolescent sports engagement in China and validate its reliability and validity.METHODS:Employing regional sampling, interviews were conducted with 20 teenagers aged 10 to 18 from the East, Central, South, Southwest, and Northwest China.Grounded theory was applied to three-level code the interview data, leading to the development of preliminary structural dimensions for family-based factors promoting adolescent sports engagement and the design of 30 initial items.Subsequently, a questionnaire test was administered to 1371 adolescents, and after filtering effective questionnaires, they were randomly divided into two groups for exploratory and confirmatory factor analysis.RESULTS:Exploratory factor analysis revealed that the scale comprised four dimensions-behavioral habits, parental sports support, family sports values, and resource investment-with a total of 13 items.Confirmatory factor analysis confirmed the effectiveness of the model structure, with all fit indices meeting the acceptance standards(χ~2/df=2.490,GFI=0.962,CFI=0.981,IFI=0.981,AGFI=0.952,RMSEA=0.052).Additionally, the overall scale and each dimension’s α coefficients ranged from 0.832 to 0.922,split-half reliability from 0.840 to 0.884,average variance extracted(AVE)from 0.624 to 0.721,composite reliability(CR)from 0.838 to 0.963,all reaching significance.CONCLUSION:The Scale for Family-Based Factors Promoting Adolescent Sports Engagement demonstrates high reliability and validity, offering an effective measurement tool for future quantitative research in this domain.更多还原
