Annual Review of Statistics and Its Application, 2016
This review introduces classical item response theory (IRT) models as well as more contemporary extensions to the case of multilevel, multidimensional, and mixtures of discrete and continuous latent variables through the lens of discrete multivariate analysis.

Abstract Since the 1960s, there has been a revolution in the approach to scale development. Called item response theory (IRT), this approach challenges the notion that scales must be long in order to be reliable, and that psychometric properties of a scale derived from one group of people cannot be applied to different groups.

During the past 30 years or so, a new theoretical basis for educational and psychological testing and measurement has emerged. It has been variously referred to as latent trait theory, item characteristic curve theory, and, more recently, item response theory (IRT).

Several user-contributed packages can fit IRT models. The packages we use the most is the ltm package by Dimitris Rizopoulos and the MCMCpack packages by Andrew Martin, Kevin Quinn, and Jong Hee Park. The eRm package by Patrick Mair, Reinhold Hatzinger, and Marco Maier also has powerful features. But our experience with eRm is limited at this time.

The Counseling Psychologist, 1999
Item response theory (IRT) seeks to model the way in which latent psychological constructs manifest themselves in terms of observable item responses; this information is useful when developing, evaluating, and scoring tests. After providing an overview of the most popular IRT models (i.e., those applicable to dichotomously keyed items) and contrasting ...

Die besondere Leistung der Item-Response-Theorie beruht auf einer spezifischen Bearbeitung der Relation von Person und Test. Wahrend die klassische Testtheorie darauf abzielt, den Test an einer Eichpopulation zu einem neutralen Messinstrument der gegebenen Antworten zu machen, verlagert die Item-Response-Theorie die Funktion der Neutralitat auf die ...

Item bias and item response theory
International Journal of Educational Research, 1989Abstract In this chapter the definition, detection, and explanation of item bias is discussed. Item bias is generally defined as conditional dependence; within the framework of item response theory the general definition implies that the item characteristic curves of two groups do not coincide.
