The Trail Making Test was administered to a sample of 661 inpatients in a publicly supported psychiatric hospital. The patients' mean IQ of 83.7 (SD = 13.0) was in the low end of the low average range. Multiple regression analysis of the scores showed significant IQ and age components of Trail Making Test scores; however, education and gender differences in performance were not significant once IQ and age were factored into the regression equation. Ability-based norms using time in seconds to completion as the score and IQ as a moderator variable are presented. Such norms allow more appropriate evaluation of the differential cognitive functioning of this population than previously published norms. Normal standard score conversions from raw scores, the intercept, regression weights for IQ and age, and standard error of the regression for both the Trails tasks are provided for individuals desiring to write a program to provide scores corrected for IQ and age.
对一家公立精神病医院的661名住院患者进行了连线测验。患者的平均智商为83.7（标准差=13.0），处于低平均范围的低端。对分数进行的多元回归分析显示，连线测验分数存在显著的智商和年龄成分；然而，一旦将智商和年龄纳入回归方程，教育程度和性别在表现上的差异并不显著。给出了以完成时间（秒）作为分数、以智商作为调节变量的基于能力的常模。与先前公布的常模相比，此类常模能够更恰当地评估该人群的差异认知功能。为希望编写一个程序以提供经智商和年龄校正分数的个人，提供了从原始分数到正常标准分数的转换、截距、智商和年龄的回归权重以及两个连线任务的回归标准误差。
