Cronbach's coefficient alpha is a widely used reliability measure in social, behavioral, and education sciences. It is reported in nearly every study that involves measuring a construct through multiple items. With non-tau-equivalent items,...
Testing Mediation in Structural Equation Modeling: The Effectiveness of the Test of Joint Significance [0.03%]
结构方程模型中的介导效应的检验：联合显著性检验的有效性分析
Craig Leth-Steensen,Elena Gallitto
Craig Leth-Steensen
A large number of approaches have been proposed for estimating and testing the significance of indirect effects in mediation models. In this study, four sets of Monte Carlo simulations involving full latent variable structural equation mode...
On the Relationship Between Classical Test Theory and Item Response Theory: From One to the Other and Back [0.03%]
经典测试理论与项目反应理论之间的关系：从一个到另一个再到前者
Tenko Raykov,George A Marcoulides
Tenko Raykov
The frequently neglected and often misunderstood relationship between classical test theory and item response theory is discussed for the unidimensional case with binary measures and no guessing. It is pointed out that popular item response...
A Simulation Study on Methods of Correcting for the Effects of Extreme Response Style [0.03%]
一种矫正极端答题方式影响的方法的模拟研究

Eunike Wetzel
The impact of response styles such as extreme response style (ERS) on trait estimation has long been a matter of concern to researchers and practitioners. This simulation study investigated three methods that have been proposed for the corr...
Automatic Coding of Short Text Responses via Clustering in Educational Assessment [0.03%]
教育测评中通过聚类自动对简短文本回答进行编码
Fabian Zehner,Christine Sälzer,Frank Goldhammer
Fabian Zehner
Automatic coding of short text responses opens new doors in assessment. We implemented and integrated baseline methods of natural language processing and statistical modelling by means of software components that are available under open li...
Unidimensional IRT Item Parameter Estimates Across Equivalent Test Forms With Confounding Specifications Within Dimensions [0.03%]
具有维度内部混淆规定的等值试卷的一维IRT项目参数估计
Ki Lynn Matlock,Ronna Turner
Ki Lynn Matlock
When constructing multiple test forms, the number of items and the total test difficulty are often equivalent. Not all test developers match the number of items and/or average item difficulty within subcontent areas. In this simulation stud...
Partially Compensatory Multidimensional Item Response Theory Models: Two Alternate Model Forms [0.03%]
部分补偿的多维项目反应理论模型：两种替代形式
Christine E DeMars
Christine E DeMars
Partially compensatory models may capture the cognitive skills needed to answer test items more realistically than compensatory models, but estimating the model parameters may be a challenge. Data were simulated to follow two different part...
Evaluating the Impact of Guessing and Its Interactions With Other Test Characteristics on Confidence Interval Procedures for Coefficient Alpha [0.03%]
猜测对系数alpha置信区间程序的影响及与其他测试特征相互作用的评估
Insu Paek
Insu Paek
The effect of guessing on the point estimate of coefficient alpha has been studied in the literature, but the impact of guessing and its interactions with other test characteristics on the interval estimators for coefficient alpha has not b...
A Latent Transition Analysis Model for Assessing Change in Cognitive Skills [0.03%]
一种用于认知技能变化评估的潜在过渡分析模型
Feiming Li,Allan Cohen,Brian Bottge et al.
Feiming Li et al.
Latent transition analysis (LTA) was initially developed to provide a means of measuring change in dynamic latent variables. In this article, we illustrate the use of a cognitive diagnostic model, the DINA model, as the measurement model in...
Further Considerations in Using Items With Diverse Content to Measure Acquiescence [0.03%]
关于使用内容多样的项目衡量 acquiescence 的进一步考虑
Chester Chun Seng Kam
Chester Chun Seng Kam
To measure the response style of acquiescence, researchers recommend the use of at least 15 items with heterogeneous content. Such an approach is consistent with its theoretical definition and is a substantial improvement over traditional m...
