The NSST was administered to 900 children aged three years to seven years, 11 months. Using a step-wise multiple regression model, the test was shortened from 20 to 11 test items receptively and expressively, while accounting for 95% of total test score variance. This shortened form, taking approximately 10 minutes to administer, was normed in six-month intervals as opposed to the one-year intervals of the original NSST. A cross validation sample of 301 children was used to demonstrate that comparable clinical decisions are made employing either form.
对900名年龄在3岁至7岁11个月的儿童进行了非言语筛选测验（NSST）。使用逐步多元回归模型，该测试分别从20个测试项目缩短至11个接受性和表达性测试项目，同时占总测试分数方差的95%。这种缩短版的测试大约需要10分钟来实施，与原始NSST的一年间隔不同，它以六个月为间隔进行了标准化。使用301名儿童的交叉验证样本表明，使用这两种形式都能做出可比的临床决策。
