Abstract
Following sport-related concussions, a multidimensional symptom interpretation may identify athletes with domain-specific problems when beginning to return-to-play (RTP). This study investigated whether a four-factor model of post-concussion symptoms (i.e., cognitive, physical, affective, and sleep-arousal) would identify student-athletes with persistent concerns not reflected by their total symptom score. Collegiate student-athletes (N=24,696) from the Concussion Assessment Research and Education consortium completed the Sport Concussion Assessment Tool – 3rd edition Symptom Evaluation at baseline and two post-injury follow-ups (i.e., beginning RTP and 6-month). Confirmatory factor analysis was used to compare one- and four-factor models of post-concussions symptoms. Normative reference data were compared across stratifications (e.g., sex and number of pre-existing health conditions) using Mann-Whitney U tests, and elevation rates (i.e., ≥84th percentile) for subscales and the total score were recorded. The four-factor model fit well before and after injury (CFIs>.95). Greater symptom severity on the subscale and total scores was associated with female sex (psps
