IRT-based clinical psychological assessment and test development




IRT based test development has been one of the most important psychometric developments during the past few decades.

This is a followup to a prior brief FYI post about an excellent review article regarding the benefits of IRT methods for psychological test development and interpretation. I have now read the article in depth and have provided additional comments and links via the IQs Reading blog feature.

Enjoy.

Applied Psych Test Development Series: Parts F--Psychometric/technical statistical analysis: Internal

The sixth in the series Art and Science of Applied Test Development is now available.

The sixth module (Part F--Psychometric/technical statistical analysis:  Internal) is now available.

In addition, I've made some edits and additions (esp. summary "Tools, Tips, and Troubles" and "Advanced Topics" slides) to prior presentations (Part A-E).

This is the sixth in a series of PPT modules explicating the development of psychological tests in the domain of cognitive ability using contemporary methods (e.g., theory-driven test specification; IRT-Rasch scaling; etc.). The presentations are intended to be conceptual and not statistical in nature. Feedback is appreciated.

This project can be tracked on the left-side pane of the blog under the heading of Applied Test Development Test Development Series.

The first module (Part A: Planning, development frameworks & domain/test specification blueprints) was posted previously and is accessible via SlideShare.

The second module (Part B: Test and item development) was posted previously and is accessible via SlideShare.

The third module (Part C--Use of Rasch scaling technology) was posted previously and is accessible via Slideshare.

The fourth module (Part D--Develop norm [standardization] plan) was posted previously and is accessible via Slideshare.

The fifth module (Part E--Calcuate norms and derived scores) was posted previously and is accessible via Slideshare.

You are STRONGLY encouraged to view them in order as concepts, graphic representation of concepts and ideas, etc., build on each other from start to finish.

Enjoy...more to come.

Quantoids corner: Rasch psychological measurement (IRT) references

Someone just asked me a question about Rasch (item response theory) measurement. I ran a search of the IAP Reference Database and flagged any reference that had "Rasch" as a keyword (in Procite). I've posted a copy in case anyone is looking for a relatively list of contemporary Rasch psychometric references.
