Abstract

The purpose of this paper is to present the conceptual foundation and methodology for the development of the Standardized Assessment of Phonology in Aphasia (SAPA). Item Response Theory (IRT) formed the basis for test construction. A model of phonology was identified, constructs within the model were delineated and items were developed. The SAPA was field tested with 47 individuals with chronic aphasia and IRT statistics were generated to answer research questions. Aphasic performance on the SAPA showed reasonable fit to the Rasch measurement model and results will be discussed in detail.
