Using Finiteness as a Clinical Marker to Identify Language Impairment

Abstract

Intervention rates for children with language impairments vary widely across reports. Unfortunately, many language tests focus on areas of language that are not problematic for children with language impairments (LI). Over twenty years of research supports limitations in finiteness as a clinical marker of LI. However, speech language pathologists (SLPs) have been reluctant to include assessments of finiteness in clinical decisions for young school-age children. This article addresses the operational definition of finiteness which may have created a barrier to its clinical use. We recommend that SLPs include the Test of Early Grammatical Impairment as a primary measure of finiteness for identifying language impairment in children between 3 and 8 years of age because of its clinical flexibility and high levels of sensitivity and specificity.
