The study included the developmental phase and reported the content, structural, criterion validity, interobserver and intra\u2010observer reliability of the chewing performance scale, which was called the Karaduman Chewing Performance Scale (<jats:styled-content style=\"fixed-case\">KCPS<\/jats:styled-content>). A dysphagia literature review, other questionnaires and clinical experiences were used in the developmental phase. Seven experts assessed the steps for content validity over two Delphi rounds. To test structural, criterion validity, interobserver and intra\u2010observer reliability, two swallowing therapists evaluated chewing videos of 144 children (Group I: 61 healthy children without chewing disorders, mean age of 42\u00b738 \u00b1 9\u00b736 months; Group <jats:styled-content style=\"fixed-case\">II<\/jats:styled-content>: 83 children with cerebral palsy who have chewing disorders, mean age of 39\u00b709 \u00b1 22\u00b795 months) using <jats:styled-content style=\"fixed-case\">KCPS<\/jats:styled-content>. The Behavioral Pediatrics Feeding Assessment Scale (<jats:styled-content style=\"fixed-case\">BPFAS<\/jats:styled-content>) was used for criterion validity. The <jats:styled-content style=\"fixed-case\">KCPS<\/jats:styled-content> steps arranged between 0\u20134 were found to be necessary. The content validity index was 0\u00b7885. The <jats:styled-content style=\"fixed-case\">KCPS<\/jats:styled-content> levels were found to be different between groups I and <jats:styled-content style=\"fixed-case\">II<\/jats:styled-content> (<jats:italic>\u03c7<\/jats:italic><jats:sup>2<\/jats:sup> = 123\u00b7286, <jats:italic>P<\/jats:italic> &lt; 0\u00b7001). A moderately strong positive correlation was found between the <jats:styled-content style=\"fixed-case\">KCPS<\/jats:styled-content> and the subscales of the <jats:styled-content style=\"fixed-case\">BPFAS<\/jats:styled-content> (<jats:italic>r<\/jats:italic> = 0\u00b7444\u20130\u00b7773, <jats:italic>P<\/jats:italic> &lt; 0\u00b7001). An excellent positive correlation was detected between two swallowing therapists and between two examinations of one swallowing therapist (<jats:italic>r<\/jats:italic> = 0\u00b7962, <jats:italic>P<\/jats:italic> &lt; 0\u00b7001; <jats:italic>r<\/jats:italic> = 0\u00b7990, <jats:italic>P<\/jats:italic> &lt; 0\u00b7001, respectively). The <jats:styled-content style=\"fixed-case\">KCPS<\/jats:styled-content> is a valid, reliable, quick and clinically easy\u2010to\u2010use functional instrument for determining the level of chewing function in children.<\/jats:p>","DOI":"10.1111\/joor.12399","type":"journal-article","created":{"date-parts":[[2016,4,4]],"date-time":"2016-04-04T21:12:48Z","timestamp":1459804368000},"page":"488-495","source":"Crossref","is-referenced-by-count":49,"title":["Development of a new instrument for determining the level of chewing function in children"],"prefix":"10.1111","volume":"43","author":[{"given":"S.","family":"Serel Arslan","sequence":"first","affiliation":[{"name":"Department of Physical Therapy and Rehabilitation Faculty of Health Sciences Hacettepe University Ankara Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Demir","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy and Rehabilitation Faculty of Health Sciences Hacettepe University Ankara Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Barak Dolgun","sequence":"additional","affiliation":[{"name":"Department of Biostatistics Faculty of Medicine Hacettepe University Ankara Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
