Recent evidence suggests that a distinction can be drawn between interests that, although characterized by unusually high intensity and\/or inflexibility, are otherwise common in terms of their content (e.g., an interest in movies or animals), labeled as restricted interests (RI), and interests that are generally not salient outside of autism (e.g., an interest in traffic lights or categorization), labeled as unusual interests (UI). The current study aimed to further characterize RI and UI by exploring their association with age, sex, IQ, and social motivation, as well as to examine differences in the adaptive benefits and negative impacts of these two subdomains. Parents of 1892 autistic children and adolescents (<jats:italic>M<\/jats:italic><jats:sub>age<\/jats:sub>\u00a0=\u00a010.82, <jats:italic>SD<\/jats:italic><jats:sub>age<\/jats:sub>\u00a0=\u00a04.14; 420 females) completed an online survey including the Dimensional Assessment of Restricted and Repetitive Behaviors and the Social Communication Questionnaire. Both RI and UI were found to be highly frequent. Sex\u2010based differences were observed in the content, but not intensity, of CI such that females were more likely to show interests with a social component. Finally, RI and UI showed distinct patterns of association with age, sex, IQ, and social motivation, as well as metrics of adaptive benefits and negative impacts. Findings afford a more nuanced understanding of sex\u2010based differences in CI and, crucially, provide preliminary evidence that RI and UI represent distinct constructs that should be studied independently in future research.<\/jats:p>","DOI":"10.1002\/aur.2863","type":"journal-article","created":{"date-parts":[[2022,12,1]],"date-time":"2022-12-01T12:42:46Z","timestamp":1669898566000},"page":"394-405","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Characterizing restricted and unusual interests in autistic youth"],"prefix":"10.1002","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2300-439X","authenticated-orcid":false,"given":"Emily","family":"Spackman","sequence":"first","affiliation":[{"name":"University of Melbourne  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5148-8358","authenticated-orcid":false,"given":"Luke D.","family":"Smillie","sequence":"additional","affiliation":[{"name":"University of Melbourne  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6951-2667","authenticated-orcid":false,"given":"Thomas W.","family":"Frazier","sequence":"additional","affiliation":[{"name":"John Carroll University  University Heights Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio Y.","family":"Hardan","sequence":"additional","affiliation":[{"name":"Stanford University  Stanford California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3351-5919","authenticated-orcid":false,"given":"Gail A.","family":"Alvares","sequence":"additional","affiliation":[{"name":"University of Western Australia  Perth Western Australia Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Whitehouse","sequence":"additional","affiliation":[{"name":"University of Western Australia  Perth Western Australia Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirko","family":"Uljarevi\u0107","sequence":"additional","affiliation":[{"name":"University of Melbourne  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,12]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0954579413000072"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.175.5.484"},{"key":"e_1_2_10_5_1","volume-title":"The interests scale","author":"Bodfish J.
