Although trait anxiety was higher in the concussion group and decreased over time, no interaction was seen, demonstrating that concussion may not affect this aspect of personality. Postinjury anxiety may result from increased state anxiety, and clinicians should screen for and manage these symptoms throughout recovery.<\/jats:p><\/jats:sec>","DOI":"10.4085\/1062-6050-0536.22","type":"journal-article","created":{"date-parts":[[2023,3,27]],"date-time":"2023-03-27T17:03:45Z","timestamp":1679936625000},"page":"775-780","source":"Crossref","is-referenced-by-count":6,"title":["Changes
