Description:
Language sample analysis measures have long been promoted as exhibiting greater ecological validity than formal testing in the assessment of language disorder in children. In practice, their use is often restricted to preschool children, owing to lack of normative information, as well as criticisms of the validity of commonly used measures for the language of older children. This study compared scores of kindergarten children (mean age 6 years) with and without specific language impairment (SLI) on three commonly used language sample analysis measures: mean length of utterance in morphemes (MLU-m), the index of productive syntax (IPSyn), and number of different words (NDWs). Mean scores of the children with SLI were significantly lower for all three measures, though not for all subtests of the IPSyn. A number of individual differences were observed; notably, several children with SLI scored as well as those without. The problems and promise of language sampling for children beyond the preschool years are discussed in light of these results. Learning outcomes:: (1) readers will gain an understanding of strengths and weaknesses of language sample measures in assessing kindergarten children with language impairment. (2) The reader will become aware of the utility of MLU in differentiating between young school age children with and without language impairment.
