Over the course of the season, 314 English-speaking players received SCAT5 evaluations within 1 day of a suspected concussive event. Of these players, 140 (45%) were subsequently diagnosed with concussion by their team physicians.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Concussed players reported more symptoms (Concussed M=8.52, SD=4.78; Control M=3.32, SD=3.97), and recalled fewer words than Controls on both the Immediate Memory (Concussed M=19.34, SD=4.06; Control M=21.53, SD=2.94) and Delayed Recall (Concussed z=\u22120.91; Control z=\u22120.09) tasks during the acute evaluation. Concussed players also made more errors than Controls on the mBESS and were more likely to report double vision and exhibit clinician-observed balance problems than controls. There were no between-group differences on the Concentration component of the SCAT5. Stepwise regression revealed that symptom report and list learning tasks both accounted for independent variance in identifying players diagnosed with concussion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These findings provide support for use of the SCAT5 to assist in identifying concussed professional hockey players. When examining SCAT5 subtests, both symptom report and the 10-item word list accounted for independent variance in identifying concussion status in this sample of professional hockey players. The mBESS also differentiated Concussed players and Controls. The Concentration component of the SCAT5 did not significantly differentiate Concussed players and Controls.<\/jats:p><\/jats:sec>","DOI":"10.1136\/bjsports-2020-102072","type":"journal-article","created":{"date-parts":[[2020,8,26]],"date-time":"2020-08-26T21:25:46Z","timestamp":1598477146000},"page":"557-565","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":29,"title":["Use of the Sport Concussion Assessment Tool 5 (SCAT5) in professional hockey, part 2: which components differentiate concussed and non-concussed players?"],"prefix":"10.1136","volume":"55","author":[{"given":"Jared M","family":"Bruce","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanie","family":"Thelen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Willem","family":"Meeuwisse","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael G","family":"Hutchison","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Rizos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Comper","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6116-8462","authenticated-orcid":false,"given":"Ruben J","family":"Echemendia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,8,26]]},"reference":[{"key":"2024101110452307000_55.10.557.1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2013-092247"},{"key":"2024101110452307000_55.10.557.2","doi-asserted-by":"crossref","first-page":"S24","DOI":"10.1227\/NEU.0000000000000505","article-title":"The new neurometabolic cascade of concussion","volume":"75 Suppl 4","author":"Giza","year":"2014","journal-title":"Neurosurgery"},{"key":"2024101110452307000_55.10.557.3","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2016-097403"},{"key":"2024101110452307000_55.10.557.4","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2017-097699"},{"key":"2024101110452307000_55.10.557.5","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2016-097393"},{"key":"2024101110452307000_55.10.557.6","doi-asserted-by":"publisher","DOI":"10.1097\/JSM.0000000000000102"},{"key":"2024101110452307000_55.10.557.7","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2005.018614"},{"key":"2024101110452307000_55.10.557.8","doi-asserted-by":"crossref","first-page":"i76","DOI":"10.1136\/bjsm.2009.058248","article-title":"Consensus statement on concussion in sport: the 3rd International Conference on concussion in sport held in Zurich, November 2008","volume":"43 Suppl 1","author":"McCrory","year":"2009","journal-title":"Br J Sports Med"},{"key":"2024101110452307000_55.10.557.9","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2013-092225"},{"key":"2024101110452307000_55.10.557.10","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2017-097506"},{"key":"2024101110452307000_55.10.557.11","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2016-097466"},{"key":"2024101110452307000_55.10.557.12","first-page":"6","article-title":"Assessment of state-trait anxiety: conceptual and methodological issues","volume":"2","author":"Spielberger","year":"1985","journal-title":"The Southern Psychologist"},{"key":"2024101110452307000_55.10.557.13","doi-asserted-by":"crossref","first-page":"291","DOI":"10.1093\/arclin\/acz007","article-title":"SCAT5 vs. SCAT3 symptom reporting differences and convergent validity in collegiate athletes","volume":"35","author":"Asken","year":"2020","journal-title":"Arch Clin Neuropsychol"},{"key":"2024101110452307000_55.10.557.14","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2016-097090"},{"key":"2024101110452307000_55.10.557.15","unstructured":"Echemendia R , Thelen J , Meeuwisse W , et al .
