Version Française du Test Numeracy Screener (NS-f), un Outil de Dépistage des Difficultés de Traitement du Nombre et des Quantités

The Numeracy Screener was developed by Dr. Nadia Nosworthy and Dr. Daniel Ansari at the Numerical Cognition Laboratory at Western University (Canada). This test is a brief (2 - 4minutes) screening tool of basic number and numerosity processing skills for children ages 5 to 9 years. The goal of the present study was to establish a French version of the Numeracy Screener (NS-f), for which the translation is valid. For that purpose, a method of back-translation was used. The results showed a good correspondence (near 80% adequation) between the original version and both retranslated versions. It thus suggests that the French version is valid. Preliminary results were also acquired and showed a coherence between scores on NS-f and the individual profiles of children. This study thus provided empirical support towards the standardization of the NS-f. This will allow, in the future, for further validity and reliability testing of the NS-f and the development of standardized norms with a tool adapted for the French-speaking population
