概化理论提出了新的测量信度观并逐渐应用于大规模考试领域。本文运用多元概化理论对高等教育自学考试课程《综合英语（四）》听力测验的测量信度、测验总分合成、题型设计优化等问题进行探讨。研究发现：本次听力测验的总体测量信度较高，但“短文理解”分测验的测量信度较低；各分测验对全域总分的方差贡献比例与测验编制时的赋分比例存在一定差距；在删除“短文理解”分测验后将各分测验题量同时增至10题，可有效提高听力测验的测量信度。
概化理論提齣瞭新的測量信度觀併逐漸應用于大規模攷試領域。本文運用多元概化理論對高等教育自學攷試課程《綜閤英語（四）》聽力測驗的測量信度、測驗總分閤成、題型設計優化等問題進行探討。研究髮現：本次聽力測驗的總體測量信度較高，但“短文理解”分測驗的測量信度較低；各分測驗對全域總分的方差貢獻比例與測驗編製時的賦分比例存在一定差距；在刪除“短文理解”分測驗後將各分測驗題量同時增至10題，可有效提高聽力測驗的測量信度。

Generalizability Theory (GT for short) puts forward a new reliability viewpoint and is gradually applied to large-scale tests. In this article, we adopt Multivariate Generalizability Theory (MGT for short) to appraise Listening Test's reliability, combination of scores as well as item format optimization based on data of Comprehensive English Four. The result shows that: a) the reliability is acceptably high for the whole Listening-Test while low for Passage-Listening-Comprehension; b) the ratio of each subtest's contribution to total variance is different from test-setters' anticipation to some degree; c) to promote test reliability, it is recommended to increase the sample size of each subtest to 10 simultaneously after abandoning Passage-Listening-Comprehension.
