A Critique to 'Using Rasch Analysis to Create and Evaluate a Measurement Instrument for Foreign Language Classroom Speaking Anxiety'

Apple (2013) published a study in a commendable attempt at bringing to light the many advantages of the Rasch models over Classical Test Theory (CTT) and other Item Response Theory (IRT) models and how they can be productively used in contexts where researchers are measuring foreign language anxiety (FLA). Of special importance, and much to Apple's credit, is the detailed procedure followed for the establishment of the unidimensionality of the Foreign Language Classroom Speaking Anxiety Scale (FLCSAS).
