Item difficulties for 10 WAIS-R subtests were determined for a sample of psychiatric inpatients (N = 150). Spearman correlation coefficients between psychiatric inpatient and standardization group rank orders were large and significant across all subtests except Object Assembly, which demonstrates the expected trend of increasing item difficulty for the psychiatric inpatient sample. Using linear regression, items with standardized residuals greater than two were judged to be significantly out of order for the psychiatric inpatient sample. Of the 165 WAIS-R items examined in this study, only 7 were found to be out of order. This result may have been due to chance and suggests that, in general, WAIS-R subtest item difficulty curves for psychiatric inpatients and the WAIS-R standardization group are comparable.
确定了150名精神科住院患者样本在韦氏成人智力量表修订版（WAIS-R）10个分测验上的项目难度。除了图片拼凑分测验外，精神科住院患者样本与标准化组的排序之间的斯皮尔曼相关系数在所有分测验中都很大且显著，这表明精神科住院患者样本的项目难度呈预期的上升趋势。使用线性回归，标准化残差大于2的项目被判定为精神科住院患者样本明显排序不当。在本研究中检查的165个WAIS-R项目中，仅发现7个排序不当。该结果可能是由于偶然因素，这表明总体而言，精神科住院患者的WAIS-R分测验项目难度曲线与WAIS-R标准化组的曲线具有可比性。
