Normative data, psychometric characteristics (i.e., internal consistency and test\u2013retest reliability), and cross\u2010cultural comparison between the EP and the original version were explored.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Outcomes &amp; Results<\/jats:title>\n                    <jats:p>Internal consistency ranged from good to excellent and the test\u2013retest reliability was excellent.

However, EP children performed significantly better than their American peers in the Social compositive at 22 months and in the Symbolic composite at 20 months.

It described the psychometric characteristics of the adapted checklist, summarized the newly available normative data for EP\u2010learning infants and toddlers, and compared the performance of EP\u2010learning children with the original standardization sample reported for American English. The results demonstrated that this tool is a reliable instrument for the early screening of language, communicative and symbolic behaviours for EP\u2010learning children between 6 and 24 months of age.<\/jats:p>\n                          <\/jats:list-item>\n                        <\/jats:list>\n                      <\/jats:p>\n                    <\/jats:sec>\n                    <jats:sec>\n                      <jats:title>What are the potential or actual clinical implications of this work?<\/jats:title>\n                      <jats:p>\n                        <jats:list list-type=\"bullet\">\n                          <jats:list-item>\n                            <jats:p>Given that early screening is crucial to promote prevention, early diagnosis and intervention, the availability of this tool is particularly relevant for children monitoring and their enrolment in appropriate early intervention services, helping decision\u2010making in clinical practice, in line with current guidelines regarding early monitoring and intervention to promote and support better outcomes. Thus, the tool and related normative data will be useful for paediatricians, family doctors, primary healthcare providers, developmental psychologists and speech\u2013language therapists, among other professionals in the healthcare and educational fields, concerned with speech, language, and communication development and impairments.<\/jats:p>\n                          <\/jats:list-item>\n                        <\/jats:list>\n                      <\/jats:p>\n                    <\/jats:sec>\n                  <\/jats:sec>","DOI":"10.1111\/1460-6984.12937","type":"journal-article","created":{"date-parts":[[2023,8,1]],"date-time":"2023-08-01T23:53:53Z","timestamp":1690934033000},"page":"223-233","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Adaptation and validation of the European Portuguese Communication and Symbolic Behaviour Scales Developmental Profile\u2122 (CSBS DP\u2122) Infant\u2013Toddler Checklist"],"prefix":"10.1111","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8612-225X","authenticated-orcid":false,"given":"Marisa G.","family":"Filipe","sequence":"first","affiliation":[{"name":"Center of Linguistics School of Arts and Humanities University of Lisbon  Lisbon Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u00e1tia","family":"Severino","sequence":"additional","affiliation":[{"name":"Center of Linguistics School of Arts and Humanities University of Lisbon  Lisbon Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Vig\u00e1rio","sequence":"additional","affiliation":[{"name":"Center of Linguistics School of Arts and Humanities University of Lisbon  Lisbon Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00f3nia","family":"Frota","sequence":"additional","affiliation":[{"name":"Center of Linguistics School of Arts and Humanities University of Lisbon  Lisbon Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,8,1]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/cdev.12973"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/aur.1624"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9781139342872.010"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1044\/jslhr.4305.1061"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/13682820500057301"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/1460\u20106984.12203"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469\u20107610.2008.01881.x"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dr.2010.10.001"},{"key":"e_1_2_9_10_1","volume-title":"The acquisition of the consonantal system in European Portuguese: focus on place and manner features","author":"Costa T.","year":"2010"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.31234\/osf.io\/8mjx9"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.3109\/13682820903277944"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.3758\/bf03193146"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/apa.15696"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467\u20108624.2005.00882.x"},{"key":"e_1_2_9_16_1","volume-title":"MacArthur Communicative Development Inventories: User's guide and technical manual","author":"Fenson L.","year":"1993"},{"key":"e_1_2_9_17_1","volume-title":"MacArthur\u2013Bates Communicative Development Inventories: User's guide and technical manual","author":"Fenson L.","year":"2007"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0142716400001053"},{"key":"e_1_2_9_19_1","unstructured":"FFMS.
