Ruytjens, Liesbet Goedegebure, André van Ingen, Gijs Franken, Marie-Christine 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) <div>"<b>Purpose:</b> The purpose of this research note was to validate a simplified version of the Dutch nonword repetition task (NWR; Rispens & Baker, 2012). 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.
