大学生社会支持评定量表的概化分析

A Generalizability Analysis of the Social Support Scale for University Students

目的:运用概化理论对大学生社会支持评定量表的测量学性能进行分析。方法:采用大学生社会支持评定量表对211名大学生进行测试,研究设计为多元ρ×i随机测量模式。结果:①大学生社会支持评定量表的3个因子之间存在中等相关;分量表概化系数和可靠性指数均接近或达到0.8,总量表的上述指标均≥0.9;②大学生社会支持评定量表的客观支持因子的分值占总分的35.29%,但其对全域方差的贡献仅占23.75%。结论:大学生社会支持评定量表的结构符合其设计理论,分量表和总量表均有较好的测量精度和信度,可以作为常模参照性测验和标准化参照性测验来使用;客观支持因子相对于其它两个因子的量表特性稍差。

Objective： In this paper,the generalizability theory was used to analyze and explore the psychometric properties of the Social Support Scale for University Students.Methods： 211 college students were surveyed with the Social Support Scale for University Students,and the study design was multivariate p×i random pattern.Results： Firstly,middle level correlation coefficients were found among the three factors;the generalizability coefficient and the index of dependability were close to or above 0.80 for each factor,and for the whole scale,they were above 0.90 respectively.Secondly,the scores of the objective support factor were 35.29% in the total scores,but the variance of the objective support factor was only 23.75% in the universe variance contribution.Conclusion： The measurement accuracy and reliability were excellent for each factor and the whole scale,and they could be used for the norm-referenced test and the criterion-referenced test;but as compared with other factors in the scale,the objective support factor should be developed in the future.
