A 37-item shoulder functional status item pool had negligible differential item functioning.
OBJECTIVE Measures of shoulder function may differ by dominance of affected shoulder, surgical history, gender, or race. We present a technique for determining whether observed differences in function between groups are due to biased test items or real differences in function. STUDY DESIGN AND SETTING Four hundred patients who were receiving rehabilitation for a variety of shoulder impairment...
متن کاملItem pool design for computerized adaptive tests
Although item pools are critical to the proper functioning of computerized adaptive tests (CATs), there is very little in the research literature that indicates the desired features of an item pool. Most research articles use an existing item pool that was developed for other purposes. For example, Pastor, Dodd and Chang (2002) used items from NAEP; Wang and Kolen (2001) used an item pool from ...

متن کاملItem Pool Construction Using Mixed Integer Quadratic Programming (MIQP)
This study uses mixed integer quadratic programming (MIQP) to construct multiple highly equivalent item pools simultaneously, and compares the results from mixed integer programming (MIP). Three different MIP/MIQP models were implemented and evaluated using real CAT item pool data with 23 different content areas and a goal of equal information functions across pools and within each content area...
