Abstract
The two-parameter graded response latent trait
model was applied to data collected from a conventionally
constructed Likert-type attitude scale. Comparisons
were made of both the person latent trait estimates
and the item parameter estimates with their
counterparts from the conventional scaling method.
Also studied were the goodness of fit of the graded response
model and the information function feature of
the model indicating the precision of measurement at
each level of the attitude trait continuum. The results
demonstrated that the graded response model could be
successfully used to perform attitude measurement for
Likert scales.
