Unidimensional Calibrations and Interpretations of Composite Traits for Multidimensional Tests.
Luecht, Richard M.; Miller, Timothy R.
Applied Psychological Measurement, v16 n3 p279-93 Sep 1992
A two-stage process that considers the multidimensionality of tests under the framework of unidimensional item response theory is described and evaluated. Findings from a simulation indicate that gains in estimation robustness and score interpretation are possible with almost no sacrifice of goodness of fit when using this two-stage approach. (SLD)
