Overview

This research proposes a generalized forced-choice diagnostic classification model for noncognitive tests, highlighting improvements in response biases and model accuracy.

Key Points

The generalized forced-choice diagnostic classification model (GFC-DCM) significantly reduces response biases in noncognitive assessments, enhancing accuracy and reliability.
A simulation study demonstrated that the GFC-DCM achieved high classification accuracy and satisfactory parameter estimation, indicating its effectiveness compared to existing models.
Control variables such as the number of statements and forced-choice format directly influenced the outcomes and overall performance of the GFC-DCM.
Empirical results showed that the GFC-DCM is superior in model fit, convergence, and diagnostic consistency, addressing key limitations of previous models.
