The Use of Unidimensional Item Parameter Estimates of Multidimensional Items in Adaptive Testing.

Download full text

Ackerman, Terry A. – 1987

The purpose of this study was to investigate the effect of using multidimensional items in a computer adaptive test (CAT) setting which assumes a unidimensional item response theory (IRT) framework. Previous research has suggested that the composite of multidimensional abilities being estimated by a unidimensional IRT model is not constant…
