Abstract Purpose To investigate predictors of prolonged recovery after concussion in collegiate athletes. Method Data for this cross-sectional, retrospective chart review of collegiate athletes diagnosed with concussion (n = 1044 concussions), who were on average 20-years of age, were collected during the 2015–16 to 2019–20 athletic seasons. The majority (92% [959/1044]) of athletes achieved symptom resolution at rest and made an unrestricted return-to-sport by 23 days after injury. The remaining athletes (8% n = 85[36.5% female]), with symptoms that lasted beyond 23 days after concussion were considered to have prolonged recovery. Linear regression was used to determine predictors of prolonged recovery; times to symptom-freedom and unrestricted return-to-sport were dependent variables and variables associated with medical and psychiatric history, and some post-concussion symptoms, were independent variables. Results Athletes with prolonged recovery generally recovered on median (interquartile range) 32 (17) days after injury. The majority (42% [36/84]) participated in football. A self-reported history of anxiety [Β = 0.577, p = 0.01], depression [Β = 0.462, p = 0.04], a history of headache [Β = 0.84, p
