Sub-analyses of the shortened nonword repetition task (NWR-S) compared with the nonword repetition task (NWR) per study group: children with specific language impairment (SLI), reading impairment (RI), both SLI and RI, and two control groups (le Clercq et al., 2017) Carlijn M.

The NWR was shortened and scoring was transformed to correct/incorrect nonwords, resulting in the shortened NWR (NWR-S).</div><div><b>Method:</b> NWR-S and NWR performance were compared in the previously published data set of Rispens and Baker (2012; <i>N</i> = 88), who compared NWR performance in 5 participant groups: specific language impairment (SLI), reading impairment (RI), both SLI and RI, one control group matched on chronological age, and one control group matched on language age.</div><div><b>Results:</b> Analyses of variance showed that children with SLI + RI performed significantly worse than other participant groups in NWR-S, just as in NWR. Logistic regression analyses showed that both tasks can predict an SLI + RI outcome. NWR-S holds a sensitivity of 82.6% and a specificity of 95.4% in identifying children with SLI + RI. The sensitivity of the original NWR is 87.0% with a specificity of 87.7%.</div><div><b>Conclusions:</b> As the original NWR, the NWR-S comprising a subset of 22 nonwords scored with a simplified scoring system can identify children with combined SLI and RI while saving a significant amount of the needed assessment time."</div><div><br></div><div><b>Supplemental Material S1.</b> Correlation plot for NWR-S compared with NWR in children with SLI + RI (<i>n</i> = 23), <i>r</i> = .716, <i>p</i> < .001.</div><div><br></div><div><b>Supplemental Material S2.</b> Correlation plot for NWR-S compared with NWR in children with SLI (<i>n</i> = 10), <i>r</i> = .750, <i>p</i> = .013.</div><div><br></div><div><b>Supplemental Material S3.</b> Correlation plot for NWR-S compared with NWR in children with RI (<i>n</i> = 14), <i>r</i> = .856, <i>p</i> < .001.</div><div><br></div><div><b>Supplemental Material S4.</b> Correlation plot for NWR-S compared with NWR in children with CA TD (<i>n</i> = 25), <i>r</i> = .792, <i>p</i> < .001.</div><div><b><br></b></div><div><b>Supplemental Material S5.</b> Correlation plot for NWR-S compared with NWR in children with LA TD (<i>n</i> = 16),<i> r</i> = .852, <i>p</i> < .001.</div><div><br></div><div>le Clercq, C.
