Scoring Subscales Using Multidimensional Item Response Theory Models [electronic resource] / Christine E. DeMars.

Several methods for estimating item response theory scores for multiple subtests were compared. These methods included two multidimensional item response theory models: a bi-factor model where each subtest was a composite score based on the primary trait measured by the set of tests and a secondary...
