Should Parents Only Use One Language with Their Autistic Children? The Relations Between Multilingualism, Children's...

Parents of autistic children are often advised to use only one language to simplify their child's language acquisition. Often this recommendation orients towards the geographically predominant language, which may cause difficulties especially for minority-language families. On the other hand, scientific evidence suggests that multilingualism does not hinder language acquisition and that communicating in exclusively foreign languages may even impede social interaction. Therefore, we investigated how parent language use is linked to the social skills of 68 autistic children and to their parents' ability to feel comfortable, authentic, and free to express themselves.

Data was collected online, using parent-report questionnaires from parents of 25 different nationalities in the European context, assessing children's language, autistic traits (AQ-C), social skills (SRS-2), and parent-child communication.

Language use was not found to significantly relate to social skills in children. However, parents using their mother tongue, either only their mother tongue or in combination with other languages, reported feeling significantly more comfortable and more authentic than parents using exclusively foreign languages, either one or many. There were no significant differences between monolingual and multilingual families regarding parents' feelings in regard to their language use.

Our findings may encourage specialists to consider multilingualism more often and consult with parents whether monolingualism is worth risking the negative outcomes we have found. Especially, since advising parents to raise their child multilingually may facilitate access to therapeutic treatment, childcare, and social interaction in multilingual societies and families and subsequently improve support and orientation for stakeholders.
