This study examined differential item function on the K-ABC for gifted and nongifted subjects on the basis of race and gender using the technique for partial correlation proposed by Stricker (1982) and Reynolds, Willson, and Chatman (1984). It was determined that there were no items biased against gifted Black children and that 8 items were biased against gifted White children. Three items were found to be biased against nongifted Black children, while 4 items were biased against nongifted White children. When gender was considered, 2 items were found to be biased against gifted males, and 2 items also were found to be biased against gifted females. There were 10 items that were biased against nongifted Black males and 6 items biased against nongifted females. Systematic bias against race or gender was not found. It appears that the K-ABC is a relatively nonbiased test suitable for the evaluation of both gifted and nongifted children regardless of race or gender.
本研究运用斯特里克（1982年）以及雷诺兹、威尔森和查特曼（1984年）提出的偏相关技术，考察了在种族和性别的基础上，天赋异禀和非天赋异禀受试者在考夫曼儿童成套评估测验（K-ABC）上的项目功能差异。结果确定，没有项目对天赋异禀的黑人儿童有偏向，有8个项目对天赋异禀的白人儿童有偏向。发现有3个项目对非天赋异禀的黑人儿童有偏向，4个项目对非天赋异禀的白人儿童有偏向。当考虑性别时，发现有2个项目对天赋异禀的男性有偏向，还有2个项目对天赋异禀的女性有偏向。有10个项目对非天赋异禀的黑人男性有偏向，6个项目对非天赋异禀的女性有偏向。未发现对种族或性别的系统性偏向。看来K-ABC是一个相对无偏向的测验，适合于评估天赋异禀和非天赋异禀的儿童，无论其种族或性别如何。
