为了更能掌握青少年事故伤害自我效能量表的理论基础与其特质，评估并探讨此量表之高阶潜在因素结构是建立此量表过程中不可或缺的重要步骤。本研究以台湾地区八十四学年度公、私立国中、高中高职日间部学生为研究母群，以「青少年事故伤害自我效能量表」为评估、探讨目标，以EQS统计软件为效度评估与探讨的主要分析工具。结果有三项主要的发现：第一、经整体暨个别的残差分析、整体模式之适配与其取代指针，以及估计参数之统计考验等结果，均指出假设此量表为二阶因素分析测量模式是相当恰当的；第二、经交互确认效度分析结果，显示此量表之二阶潜在因素结构是非常稳定；第三、经多组别不变量统计考验结果，指出此量表之二阶潜在因素结构，对于学校别、性别、年级、用手习惯，以及过去伤害经验这些社会人口变项，大致上具有因素个数、因素负荷量、因素变异数，以及测量误差变异数等不变量的特性。

It is essential to evaluate the higher-order latent factor structure of the adolescent self-efficacy scale in unintentional injury in order to comprehend its theoretical foundation and characteristics. The 9,770 students, randomly sampled from junior high, senior high, and vocational schools of the 1995-1996 academic year in Taiwan, were administered this scale, and the statistical program, EQS 5.3 for Windows, was used for the major tool of data analysis. There were three major findings. (1) On the basis of the assessment of overall model fit and parameter estimates, the hypothesized second-order confirmatory factor analysis model represented an adequate fit to the sample data. (2) According to the cross-validation analysis, the second-order factorial validity of this scale was very stable. (3) This hypothesized model was invariance across these five important demographical variables, including school, gender, grade, right/left-handedness, and past experience in unintentional injury, via the testing of invariance in the multiple groups.
