This simulation study investigated the impact of Qmatrix
misspecification and model misuse on examinees’ classification accuracy within
the generalized deterministic input, noisy “and” gate (GDINA) model framework
under various conditions. The data was generated in the saturated GDINA model.
Along with the
generating model, two reduced models were used to fit the data: the additive CDM (ACDM)
and DINA model. The manipulated conditions included: number of respondents,
attribute correlations and test length. Two types of
classification accuracy were examined: the overall classification accuracy and the classspecific
classification accuracy. Results showed that the Qmatrix
misspecification influenced classification accuracy more ominously than model
misuse. The proportion of
examinees classified correctly for each latent class was related to the types
of Qmatrix misspecification. More test items had greater positive impact on
classification accuracy than more respondents taking the test.
