Walter P. Vispoel; Hyeri Hong; Hyeryung Lee; Terrence D. Jorgensen – Applied Measurement in Education, 2023
We illustrate how to analyze complete generalizability theory (GT) designs using structural equation modeling software ("lavaan" in R), compare results to those obtained from numerous ANOVA-based packages, and apply those results in practical ways using data obtained from a large sample of respondents, who completed the Self-Perception…

Fan, Xitao; Sun, Shaojing – Journal of Early Adolescence, 2014
In adolescence research, the treatment of measurement reliability is often fragmented, and it is not always clear how different reliability coefficients are related. We show that generalizability theory (G-theory) is a comprehensive framework of measurement reliability, encompassing all other reliability methods (e.g., Pearson "r,"…

Holster, Trevor A.; Lake, J. – Language Assessment Quarterly, 2016
Stewart questioned Beglar's use of Rasch analysis of the Vocabulary Size Test (VST) and advocated the use of 3-parameter logistic item response theory (3PLIRT) on the basis that it models a non-zero lower asymptote for items, often called a "guessing" parameter. In support of this theory, Stewart presented fit statistics derived from…

One criticism concerns the issue of measurement bias in cognitive ability tests with respect to specific groups in society. Sacked et AL. (2008) stated that "absent additional information, one cannot…

Sackett, Paul R.; Borneman, Matthew J.; Connelly, Brian S. – American Psychologist, 2009
We are pleased that our article prompted this series of four commentaries and that we have this opportunity to respond. We address each in turn. Duckworth and Kaufman and Agars discussed, respectively, two broad issues concerning the validity of selection systems, namely, the expansion of the predictor domain to include noncognitive predictors of…
