Comparing Rasch measurement and factor analysis
Structural Equation Modeling: A Multidisciplinary Journal, 1996This article illustrates how Rasch measurement is preferable to factor analysis for reducing complex data matrices to unidimensional variables. The two methods: (a) address the same kind of data, but with different interpretations of numerical status; (b) use the same estimation methods, but with different measurement models; and (c) solve the same ...

Rasch analysis of the carpal tunnel syndrome instrument
Journal of Hand TherapyThe carpal tunnel syndrome instrument (CTSI) is the most widely used patient-reported outcome measure (PROM) in carpal tunnel syndrome (CTS). However, CTSI is an ordinal-type questionnaire and might have caused misinterpretations of the PROM between surgical outcomes of CTS (Camitz and extra/open carpal tunnel release).This study aims to convert the ...

The Rasch Model for Item Analysis
1987The so-called Rasch model, now widely employed for item analysis, is only one of a complete family of models described by Rasch in his 1960 text. All may be properly called “Rasch Models” since they share a common feature which Rasch labeled “specific objectivity”. This is a property of most measurement systems which requires that the comparison of any

Item Analysis e modello di Rasch
1987Analisi di questionari per la ricerca educativa (pedagogia sperimentale). Si presenta nel contesto ducativo italiano la procedura di Rasch, validandola su alcuni questionari. Si discutono vantaggi di questa procedura rispetto ai modelli più tradizionalmente noti di item analysis.
