Results: A three‐profile model was the best fit for both analyses, with each analysis yielding a low ASD symptom profile, an elevated or mixed ASD symptom profile and a high ASD symptom profile. Associations were observed between profile probability scores and IQ, the number of co‐occurring biomedical conditions reported, sex, and SRS‐2 form. Conclusions: Characterising heterogeneity in ASD symptom profiles can inform more personalised supports in this population, and implications for potential therapeutic approaches for individuals with DS are discussed.</jats:p>","journal":"Journal of Intellectual Disability Research","year":2022,"id":639496,"datarank":0.7240519945562821,"base_score":3.1354942159291497,"endowment":3.1354942159291497,"self_citation_contribution":0.47032413238937254,"citation_network_contribution":0.25372786216690957,"self_endowment_contribution":0.47032413238937254,"citer_contribution":0.25372786216690957,"corpus_percentile":72.8,"corpus_rank":3684,"citation_count":22,"citer_count":17,"citers_with_citation_signal":14,"citers_with_endowment":14,"datacite_reuse_total":0,"is_dataset":true,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1661539,"name":"M.
