Complex syntax production in preschool children with hearing loss who use spoken language has been explored minimally. The purpose of this study was to compare complex syntax production of 4-year-old children with hearing loss to age-matched and language-matched peers with normal hearing.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Method<\/jats:title>\n            <jats:p>Seventy-two children completed a language assessment battery, including a structured language sample. Complex syntax density and number and accuracy of productions of particular types of complex syntax were compared across three groups: 4-year-old children with hearing loss, an age-matched group of children with normal hearing, and an mean length of utterance (MLU)\u2013matched group of children with normal hearing.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Children with hearing loss had lower complex syntax density and fewer correct productions of coordinated clauses, subordinate clauses, and simple infinitives than their age-matched, but not language-matched, peers. Furthermore, children with hearing loss had lower accuracy than the age-matched group on simple infinitives and lower accuracy than both the age- and MLU-matched groups on full propositional complements and subject relative clauses.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Children with hearing loss exhibit delays in complex syntax acquisition as compared to their same-age peers and disruptions in development on some complex structures as compared to MLU-matched, younger children.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Supplemental Material<\/jats:title>\n            <jats:p>\n              <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/doi.org\/10.23641\/asha.14080193\">https:\/\/doi.org\/10.23641\/asha.14080193<\/jats:ext-link>\n            <\/jats:p>\n          <\/jats:sec>","DOI":"10.1044\/2020_ajslp-20-00178","type":"journal-article","created":{"date-parts":[[2021,3,1]],"date-time":"2021-03-01T23:14:13Z","timestamp":1614640453000},"page":"609-621","source":"Crossref","is-referenced-by-count":22,"title":["The Production of Complex Syntax in Spontaneous Language by 4-Year-Old Children With Hearing Loss"],"prefix":"10.1044","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2599-4609","authenticated-orcid":false,"given":"Krystal L.","family":"Werfel","sequence":"first","affiliation":[{"name":"Department of Communication Sciences and Disorders, University of South Carolina, Columbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriella","family":"Reynolds","sequence":"additional","affiliation":[{"name":"Department of Communication Sciences and Disorders, University of South Carolina, Columbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Hudgins","sequence":"additional","affiliation":[{"name":"Department of Communication Sciences and Disorders, University of South Carolina, Columbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marissa","family":"Castaldo","sequence":"additional","affiliation":[{"name":"Department of Communication Sciences and Disorders, University of South Carolina, Columbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4992-3554","authenticated-orcid":false,"given":"Emily A.","family":"Lund","sequence":"additional","affiliation":[{"name":"Davies School of Communication Sciences &amp; Disorders, Texas Christian University, Fort Worth"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1310","reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1044\/2017_JSLHR-L-17-0105"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/TLD.0b013e31828f9ee8"},{"key":"e_1_3_2_4_1","doi-asserted-by":"publisher","DOI":"10.2307\/1130691"},{"key":"e_1_3_2_5_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0305000900005833"},{"key":"e_1_3_2_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/1469-7610.00726"},{"key":"e_1_3_2_7_1","doi-asserted-by":"publisher","DOI":"10.4159\/harvard.9780674732469"},{"key":"e_1_3_2_8_1","volume-title":"Expressive One-Word Picture Vocabulary Test\u2013Fourth Edition","author":"Brownell R.","year":"2011","unstructured":"Brownell, R.
