摘　　要：本研究基于整体效度观理论,运用因子分析法抽取已有听力测试的构念,验证据此听力构念编写仿真测试和建构测试效度的可行性。选取雅思听力真题为效标,对被试成绩进行探索性因子分析,提取出效标测验的构念,根据分析结果开发新的听力测验,并通过同一批被试的测验结果验证新测试的构念效度、效度关联度和信度等参数。结果显示,用因子分析法抽取并仿真重建测试的构念效度成分是可行的,据此编写的新测验在构念效度、效标效度、信度相关、内部一致性信度、难度和方差等测试重要属性上均和原测试高度相关。The present study,grounded on the unitary concept of validity,extracts the construct validity framework through exploratory factor analysis(EFA),and studies the feasibility of simulating construct validity of an established listening test.Taking one IELTS listening test as criterion-test,the study applies EFA to its test scores to filter out its construct validity framework.A new test made in accordance with the construct framework is then analyzed in terms of its construct validity,criterion-related validity and its reliability.The results confirm the quality of extracting and simulating the construct validity of a test.Statistical analysis shows that the two tests are significantly correlated in terms of construct validity,criterion validity,reliability of correlation,inneritem reliability,difficulty and test score's variance.
