Diagnostic Classification Models: Thoughts and Future Directions
Henson, Robert A.
Measurement: Interdisciplinary Research and Perspectives, v7 n1 p34-36 Jan 2009
The paper by Drs. Rupp and Templin provides a much needed step toward the general application of diagnostic classification modeling (DCMs). The authors have provided a summary of many of the concepts that one must consider to properly apply a DCM (which ranges from model selection and estimation, to assessing the appropriateness of the model using methods of model fit) in a way that is accessible to a broader audience. However, the author suggests that another area of much needed research is test development. Specifically, it may be intuitive that items should not be written in the same way as they have been written when a traditional analysis is the focus, but how this procedure should differ needs to be addressed. By discussing test development, DCMs will continue to become a possible alternative to common methodologies of psychometrics.
