Deygers, Bart; Van Gorp, Koen – Language Testing, 2015
Considering scoring validity as encompassing both reliable rating scale use and valid descriptor interpretation, this study reports on the validation of a CEFR-based scale that was co-constructed and used by novice raters. The research questions this paper wishes to answer are (a) whether it is possible to construct a CEFR-based rating scale with…

Oon, Pey-Tee; Fan, Xitao – International Journal of Science Education, 2017
Students' attitude towards science (SAS) is often a subject of investigation in science education research. Survey of rating scale is commonly used in the study of SAS. The present study illustrates how Rasch analysis can be used to provide psychometric information of SAS rating scales. The analyses were conducted on a 20-item SAS scale used in an…

Looney, Marilyn A. – Measurement in Physical Education and Exercise Science, 2012
The purpose of this study was to determine if the 2010 Olympic figure skating judges had trouble scoring Plushenko and the transitions program component, and if the International Skating Union's (ISU) "corridor" method flagged the same judging anomalies as the Rasch analyses. A 3-facet (skater by program component by judge) Rasch rating…

Dinno, Alexis – Multivariate Behavioral Research, 2009
Horn's parallel analysis (PA) is the method of consensus in the literature on empirical methods for deciding how many components/factors to retain. Different authors have proposed various implementations of PA. Horn's seminal 1965 article, a 1996 article by Thompson and Daniel, and a 2004 article by Hayton, Allen, and Scarpello all make assertions…

Hwang, Heungsun; Desarbo, Wayne S.; Takane, Yoshio – Psychometrika, 2007
Generalized Structured Component Analysis (GSCA) was recently introduced by Hwang and Takane (2004) as a component-based approach to path analysis with latent variables. The parameters of GSCA are estimated by pooling data across respondents under the implicit assumption that they all come from a single, homogenous group. However, as has been…

Janssen, Rianne; De Boeck, Paul – Applied Psychological Measurement, 1997
Used the multicomponent latent trait model (MTLM) (S. Embretson, 1980, 1984) for 3 different synonym tasks completed by 212 and 257 Belgian secondary school students. Developed a heuristic evaluation procedure that tested features of the model and provided an explanation for why the MTLM did not fit the data. (SLD)

Kim, Sooyeon; Kyllonen, Patrick C. – ETS Research Report Series, 2006
The Standardized Letter of Recommendation (SLR), a 28-item form, was created by ETS to supplement the qualitative rating of graduate school applicants' nonacademic qualities with a quantitative approach. The purpose of this study was to evaluate the following psychometric properties of the SLR using the Rasch rating-scale model: dimensionality,…
