Validation of a scale for a nonword repetition task to assess lexical development

It has been demonstrated that the ability to repeat non-words is a good marker of lexical development in a number of languages, including Spanish. In addition, the ability to repeat nonwords has been used as a good discriminator between typically developing children and children with language delays or other language difficulties. However, despite its potential usefulness for clinical and research purposes, there is no validated scale in Spanish. To address this situation, we present a scale based on a sample of 342 monolingual Spanish-speaking children aged from four to seven years. After data analysis, a scale was elaborated to provide populational references for colleagues working in educational, clinical and research fields. The results show a ceiling effect for six years olds, as well as for monomorphemic and bisyllabic items. Implications of these scores are discussed in the corresponding section.
