Abstract
A group of covariance structure models was examined
to ascertain the similarity between conventionally
administered and computerized adaptive (CAT) versions
of the complete battery of the Differential Aptitude
Tests (DAT). Two factor analysis models developed
from classical test theory and three models with a
multiplicative structure for these multitrait-multimethod
data were developed and then fit to sample
data in a double cross-validation design. All three direct-product models performed better than the factor
analysis models in both calibration and cross-validation
subsamples. The cross-validated, disattenuated
correlation between the administration methods in the
best-performing direct-product model was very high in
both groups (.98 and .97), suggesting that the CAT
version of the DAT is an adequate representation of the
conventional test battery. However, some evidence
suggested that there are substantial differences between
the printed and computerized versions of the
one speeded test in the battery. Index terms: adaptive
tests, computerized adaptive testing, covariance
structure, cross-validation, Differential Aptitude Tests,
direct-product models, factor analysis, multitrait-multimethod
matrices.
