Although the items within the WAIS-R subtests are presumed to be in ascending order of difficulty, several studies have indicated that the Picture Arrangement subtest items are out of order for clinical groups. The present study retrospectively examined item difficulty and discrimination in the test data of 74 individuals who had been referred for neuropsychological assessment following a traumatic brain injury. While results were not statistically significant, qualitative analysis of partial credit scoring for four of the items indicated some inconsistencies in the scoring rationale. Caution is recommended in the use and interpretation of the Picture Arrangement tests scores in the assessment of individuals with traumatic brain injury.
尽管韦氏成人智力量表修订版（WAIS-R）各分测验中的题目被认为是按照难度升序排列的，但多项研究表明，对于临床群体而言，图片排列分测验的题目顺序并不正确。本研究回顾性分析了74名因创伤性脑损伤而接受神经心理学评估者的测验数据中的题目难度和区分度。虽然结果无统计学意义，但对其中4个题目的部分计分进行的定性分析表明，计分原理存在一些不一致之处。在对创伤性脑损伤患者进行评估时，建议谨慎使用和解释图片排列测验的分数。
