Identifying Language Disorder Within a Migration Context: Development and Performance of a Pre-school Screening Tool for Children With German as a Second Language.

Background: There is a lack of accurate and practicable instruments for identifying language disorders in multilingual children in pre-school settings.

Objective: To develop a language screening instrument for pre-school children who are growing up with German as their second language.

Design: After the development and initial validation of a language screening tool, the new instrument (LOGiK-S) was administered to three cohorts of children (2014, 2015, 2017) with a non-German first language attending a variety of public pre-schools in Upper Austria.
