青少年体育锻炼阻碍因素研究——基于结构方程模型

Model of Obstacles of Teenager Physical Exercise Based on SEM

青少年体育锻炼水平的高低直接影响其健康水平,明晰青少年体育锻炼的阻碍性因素,对施加针对性的干预措施和提高青少年体育锻炼水平具有重要意义。运用文献资料法和调查法,制定了青少年体育锻炼障碍问卷,通过因子分析筛选出19个评价模型的观察指标。在最大方差旋转方法之后,由因子加载矩阵确定四个维度,并且执行验证性因子分析。利用结构方程模型(SEM)构建阻碍青少年体育锻炼的模型,并对模型进行各拟合优度指标检验,最后对模型进行路径分析,得出学校、家庭、社会和个人态度这四个因子对青少年体育锻炼的阻碍作用程度,并提出了指导性建议。

The level of physical exercise of teenagers has a direct impact on their health.It is of great significance to clarify the impeding factors of physical exercise of teenagers and to apply targeted intervention measures to improve the level of physical exercise of teenagers.By using the method of literature and investigation,the questionnaire on the hindrance factors of teenagers physical exercise was made and19 observation indexes of evaluation model were screened out by factor analysis.Four dimensions were determined by the factor load matrix rotated by the maximum variance method,and the confirmatory factor analysis was carried out.The model of hindering teenager physical exercise was constructed by using structural equation model(SEM).The goodness of fit index of the model was tested.Finally,the path of the model is analyzed and the conclusion is drawn.
