Analysis of the relationship between the Expressive One-Word Picture Vocabulary Test and Stanford-Binet Intelligence Scale, Peabody Picture Vocabulary Test, Developmental Test of Visual-Motor Integration, and three language subscales within the Stanford-Binet was performed on a sample of preschool children within the borderline and mildly retarded ranges of intelligence. Adequate convergent and discriminant validity indices were found to support tentatively the use of the Expressive One-Word Test as one measure of verbal intelligence with this population.Requests for reprints should be sent to Donald J.
