Note. The primary values in this table are from youth who reported previous treatment for a psychiatric condition and at least one symptom on the Post-Concussion Symptom Scale (boys: n = 963; girls: n = 1,449). The values provided in parentheses are the rates for larger samples of youth with a history of psychiatric treatment, including those who reported no symptoms on the Post-Concussion Symptom Scale (boys: n = 1,183; girls: n = 1,676). As presented above, symptom endorsement frequencies were higher after excluding those reporting no symptoms.
