Abstract
Narratives generated by 32 children (aged 8 to 9 years), 16 with language impairment (LI) identified during an interdisciplinary neurodevelopmental assessment and 16 with typical development (TD), were coded to determine the proportion of restricted utterances (following procedures from Hoffman, 2009). Then a comparison between group performance and an exploration of diagnostic accuracy using this measure was conducted. Results largely replicate findings from Hoffman (2009) with group comparison between TD and LI groups indicating significant differences (t-test for independent samples, p < 0.05) in proportion of restricted utterances. As in Hoffman’s study, this difference allowed for moderate diagnostic sensitivity when identifying language impairment using a diagnostic cut-off score of greater than or equal to 14% (derived from Hoffman’s research). Results failed, however, to replicate similar diagnostic specificity. Results support further development of this simple narrative analysis tool for identifying underlying language impairment in school-aged clinical populations.
