"青少年学生生活满意度量表"的概化理论研究

概化理论是用统计调整技术分析测量误差的一种测量理论,它侧重于从宏观方面讨论实测时的测量条件与结论推广应用范围之间的关系来探讨测量的外部效度问题。本文用概化理论对青少年学生生活满意度量表(CASLSS)进行了研究,得到以下研究结果:(1)对于生活满意度的维度数目,就我国青少年学生而言取6到8个维度较为合适,当对CASLSS取2个维度时,CASLSS只适合作常模参照性解释,而不适合作标准参照性解释;(2)CASLSS的各分量表和总量表的信度较高,且它不仅可以作常模参照性解释,还适合作标准参照性解释;(3)CASLSS的环境满意度因子相对其它五个因子而言,量表特性稍差,是今后改进该量表的主要方向。CASLSS无论是各个因子还是总量表均具有非常优良的量表特性,值得在实际的工作和研究中加以推广应用。

A Study of Life Satisfaction Scales Applicable to Chinese Adolescent Students by the Generalizability Theory

In this study,we used the generalizability theory to analyze the Life Satisfaction Scales Applicable to Chinese Adolescent Students.Random effect variance and covariance components were estimated in the G study.Generalizability coefficients for each latent factor of the scale and composite generalizability coefficients for the whole scale were estimated in the subsequent D study.The results show that it is suitable to count 6 to 8 dimensions about the life satisfaction dimension number of Chinese adolescent students,and in CASLSS,when 2 dimensions are counted,it is unsuitable to explain by the criterion-referenced test,and that the generalizability coefficient and the index of dependability were acceptable to the whole scale and each factor,but relative to other factors,the surrounding satisfaction factor should be developed.
