Young Children with Language Difficulties: a Dimensional Approach to Subgrouping

A dimensional approach was used to create bottom-up constructed subgroups that captured the behavioral heterogeneity in 36 Dutch-speaking children with language difficulties. Four subgroups were delineated based upon differences in cognitive ability, symbol understanding, joint attention and autism spectrum disorder related characteristics. Children with a different developmental disorder were found within a single cluster. Therefore, the results of this study suggest that bottom-up constructed subgroups might capture the heterogeneous behavioral profiles of young children with developmental difficulties in a more meaningful way. Furthermore, joint attention and symbol understanding seem important skills to assess in young children presenting with language difficulties.
