Handbook of Educational Measurement and Psychometrics Using R

The Spanish Version of the Internet Gaming Disorder Scale-Short Form (IGDS9-SF): Further Examination Using Item Response Theory

“…In comparison with CTT, IRT models present with unique advantages such as giving more information about the quality of the items and providing measures of precision at different levels of the trait ( θ ) [ 57 ]. Because of the ordinal nature of the nine IGDS9-SF items, three models for polytomous items were fitted [ 58 ]. These were the partial credit model (PCM) [ 59 ], the generalized partial credit model (GPCM) [ 60 ], and the graded response model (GRM) [ 61 ].…”

profileR: An R package for profile analysis

“…profileR has been used in education, counseling, and to study learning behavior in mice. The package has been featured in a handbook on measurement and psychometrics in R (Desjardins & Bulut, 2018); used in workshops and graduate level courses; is a part of the psychometric CRAN task view; and is downloaded, on average, 752 per month from CRAN. Our focus on R novices and usability, should help to expand the reach of profile analysis into new scientific disciplines.…”

Book Review: Modern Psychometrics With R

“…To sum up, the book is a valuable and well-structured resource that forms links to a variety of R packages and, therefore, differs in content and depth from many other psychometrics books (e.g., Beaujean, 2014;Desjardins and Bulut, 2018;Paek and Cole, 2019). Given the variety of R packages used, I would have preferred the author to consistently use the package :: function notation to write the R function throughout the book 1 .…”
