The Value of Response Times in Item Response Modeling [PDF]
Measurement: Interdisciplinary Research and Perspectives, 2015 A new and very interesting approach to the analysis of responses and response times is proposed by Goldhammer (this issue). In this approach, differences in the speed-ability compromise within respondents are considered to confound the differences in ability between respondents.

Bias-Corrected Root Mean Square Deviation Estimators
FoundationsThe root mean square deviation (RMSD) is a widely used item fit statistic in item response models. However, the sample RMSD is known to exhibit positive bias in small samples. To address this, seven alternative bias-corrected RMSD estimators are proposed

Logistic response models with item interactions [PDF]
British Journal of Mathematical and Statistical Psychology, 2011 Items that are clustered according to shared content may violate the principle of conditional independence commonly used in item response theory. This paper investigates the capabilities of a logistic item response model in relation to locally dependent item responses.
