Julien Mayor: En kortversjon av MacArthur-Bates CDI med høy nøyaktighet

Julien Mayor er førsteamanuensis ved Psykologisk institutt, UiO. Han kommer på Forum for klinisk lingvistikk og språktilegnelse for å vise fram en ny kortversjon av foreldrerapporteringsskjemaet MacArthur-Bates Communicative Development Inventories.

Foredraget holdes på engelsk, og er åpent for alle. Under følger et kort sammendrag.

A short version of MacArthur-Bates Communicative Development Inventories of high accuracy

MacArthur-Bates Communicative Development Inventories (CDIs; Fenson et al., 2007) are one of the most widely-used evaluation tool of early language development. CDIs are filled in by parents or caregivers of young children by indicating which of a pre-specified list of words and/or sentences their child understands and/or produces. Despite its success, its administration is time-consuming and can be of limited use in clinical settings, multilingual environment or when parents possess low literacy skills. I will present a new method in which an estimation of the full-CDI score is obtained by combining parental responses on a limited set of words randomly sampled from the full CDIs with vocabulary information extracted from the WordBank database (Frank et al., 2017), sampled from age-, gender- and language-matched participants. Real-data simulations using CDI-WS for American English, German and Norwegian as examples revealed high accuracy and reliability of the instrument even for tests having just 25 words, effectively cutting administration time to a couple of minutes. Empirical validation with new participants confirmed the robustness of the test (Mayor & Mani, 2018). Beta versions of an app (available for iOS and Android) and of a web-interface implementing the instrument are currently being tested and will be made available for researchers over the coming months.
