The paper reports data from four studies using the Language Development Survey (LDS), a screening tool for the identification of language delay in two-year-old children. The LDS was found to have excellent sensitivity and specificity. Prevalence data using the LDS are reported, comparing three different severity cutoffs. (Author/DB)

This study compared four commonly used vocabulary tests to screen or identify preschool children for specific language impairment (SLI). Four- and five-year olds with (N=31) and without (N=31) SLI were compared on the tests. Despite moderate to strong inter-test correlations, no test was a strong identifier of SLI. (Author/DB)
