A sample of 486 male veteran psychiatric patients at a Veterans Administration medical center were used to compare five different methods of estimating IQs from Shipley Scale scores. The methods were: (1) Grayson VA norms; (2) Paulson and Lin Table 5; (3) age-corrected Paulson and Lin Table 4; (4) Zachary et al. continuous age norms; and (5) Tamkin and Jacobsen method applying age-correction to Paulson and Lin's Table 5. An intercorrelation matrix, mean, standard deviation, and range were computed for all five IQ estimates. The same analyses were computed separately by age decade. The results suggest the advisability of using age-corrected norms for estimating IQ from the Shipley Scale. Norms uncorrected for age result in underestimates for older subjects. The Zachary et al. and Tamkin and Jacobsen methods yielded highly similar results.
在一家退伍军人管理局医疗中心，抽取了486名男性退伍军人精神病患者作为样本，用于比较从希普利量表得分估算智商的五种不同方法。这些方法分别是：(1) 格雷森退伍军人管理局常模；(2) 保尔森和林的表5；(3) 年龄校正后的保尔森和林的表4；(4) 扎卡里等人的连续年龄常模；以及(5) 坦金和雅各布森将年龄校正应用于保尔森和林的表5的方法。计算了所有五种智商估算值的相互关系矩阵、均值、标准差和范围。按年龄十年分别进行了相同的分析。结果表明，使用年龄校正后的常模从希普利量表估算智商是可取的。未进行年龄校正的常模会导致对老年受试者的低估。扎卡里等人的方法和坦金与雅各布森的方法产生了高度相似的结果。
