Background: The cultural and language diversity across many European countries presents a range of challenges and opportunities for speech and language therapists and other practitioners working with children with developmental language disorders (DLD) and their families. Objective: The aim of this study was to explore practitioners' perceptions of cultural and linguistic differences in response to children with DLD across different countries. Methods: A survey was developed by practitioners and researchers working with children with DLD across Europe and beyond as part of the work of Cost Action IS1406. Data from 1,358 practitioners from 8 European countries - Ireland, UK, Bulgaria, Poland, Croatia, Spain, Norway and Sweden - and 2 neighbour countries - Turkey and Lebanon - were included in the present analyses, which address two groups of questions. The first focuses on practitioners' perceptions of the way that parents think about cultural differences and their relationship to language development in their children. The second concerns the extent to which practitioners consider themselves to have the skills to work with children from other cultures and using different languages. Results/Conclusions: Most countries present a similar profile with intermediate results about their perception of cultural issues, but Lebanon and Turkey are the group with the most positive responses. In terms of bilingual issues most practitioners indicated that they only worked in their country's primary language. The only country where this was not the case was Lebanon. Professionals from Spain and Lebanon form a subgroup in terms of their confidence to work with different cultural/language groups. The paper highlights both the universal importance of cultural and linguistic competence in managing young children's needs and indicates that in most cases professionals do not think they have the necessary expertise to work with cultural and linguistic diversity.
