Internal consistency of the Northwestern Syntax Screening Test.
This study was designed to evaluate the usefulness of the 40 receptive and 40 expressive items of the Northwestern Syntax Screening Test. Twenty preschoolers with normal language development, 20 preschoolers functioning within the range of normal intelligence diagnosed as language impaired, and 20 mentally retarded children comprised the three subject groups. The subjects were equated for mental age. Stable Hoyt's reliability coefficients indicated that the Northwestern Syntax Screening Test assessed consistently the syntax and morphology used by children with atypical language development. Detailed item analysis revealed the strengths and weaknesses of both receptive and expressive items.
