Scoring Subscales Using Multidimensional Item Response Theory Model, Christine E. Demars
Scoring Subscales Using Multidimensional Item Response Theory Model, Christine E. Demars
Department of Graduate Psychology - Faculty Scholarship
Several methods for estimating item response theory scores for multiple subtests were compared. These methods included two multidimensional item response theory models: a bifactor model where each subtest was a composite score based on the primary trait measured by the set of tests and a secondary trait measured by the individual subtest, and a model where the traits measured by the subtests were separate but correlated. Composite scores based on unidimensional item response theory, with each subtest borrowing information from the other subtest, as well as independent unidimensional scores for each subtest were also considered. Correlations among scores from all …

University students responded to a survey measuring identity development using a 4-point Likert-type scale with two additional options: neutral and unsure. The level of identity development of students who chose neutral was compared to the level of identity development of students who chose unsure on the same item. On average, these two groups of students had similar scores. Neutral and unsure did not seem to be used to indicate different levels of the construct of interest. Often these two categories were used as a middle response, but on one scale they were used as a moderately high response
