The correct language to refer to someone with a diagnosis of autism spectrum disorder has received a lot of attention in recent years. Studies in English-speaking countries found a main identity-first language (IFL) preference (e.g. autistic person) opposed to a person-first language preference (PFL) (e.g. person with autism) among adults with autism. However, a recent study conducted in a Dutch-speaking country (the Netherlands) reported a PFL preference (Buijsman et al.,
2023). The goal of the current study was to gain insights into language preferences in two Dutch-speaking countries and, in contrast to previous studies, give participants the option to indicate not having a specific language preference. In the current study, we asked 414 Dutch-speaking adults with autism, living either in Belgium or the Netherlands, to fill in an online questionnaire about their language preference. We found that over half of the participants had a PFL preference (54%), followed by having no preference (27%). Only 14% of them had an IFL preference, and 5% proposed another term. Having more years of education was identified as a predictor for having an IFL preference when compared to a PFL preference, while being older predicted having no preference compared to a PFL preference. The majority of Dutch-speaking adults with autism showed a PFL preference, which is in contrast to findings from English-speaking countries, but in accord with a recent study conducted in the Netherlands (Buijsman et al.,
2023). Implications of this finding for language use are discussed.
