The development of equivalent lists in the Cantonese Spoken Word Recognition Test (CanSWORT)
Refereed conference paper presented and published in conference proceedings

Other information
Equivalent lists are essential in speech perception tests so that accurate repeated measurement of test takers could be obtained for performance comparison purpose. This study aims at using a mathematical modelling known as Rasch analysis to derive wordlists with equivalent level of difficulty.
Material and Methods
The study included a total of 255 children with normal hearing and 121 children with various degree of hearing impairment. Their responses on 120 test items were collected. Equivalent word lists were developed based on Rasch Analysis under the Item Response Theory. In addition, qualitative analyses based on expert opinion were also adopted in the item selection process.
A total of 80 items were selected based on the criteria of 1) infit mean square statistics of < 1.50, 2) outfit mean square statistics of <1.50 and, 3) qualitative expert opinion. With reference to the Rasch difficult measures, the 80 items were distributed into 4 word lists each with 20 items. Inter-list correlation coefficients of the 4 word lists ranged from 0.95 to 0.99 (p < 0.01).
In the validated test knows as the Cantonese Spoken Word Recognition Test (CanSWORT), four equivalent word list were developed. Taking the factors of person ability and item difficulty into account, Item Response Theory provides a more precise psychometric measurement than classical test theory in clinical test development.
