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. |
