AbstractPersistent concussion symptoms in adolescents are associated with lower health-related quality of life (HRQOL). The association between persistent emotional and behavioral-related concussion symptoms (EBS) and HRQOL is unknown, however. This study was a prospective cohort of adolescent athletes presenting to a concussion clinic within three days post-concussion and completing a one-month follow-up. The independent variable in these analyses was parent reported EBS symptom presence grouped as: (1) no EBS; (2) EBS present at pre-concussion levels; and (3) EBS worse than pre-concussion. The EBS included the following concussion symptoms: feeling irritable, depressed, frustrated/impatient, restless, reduced tolerance to stress/emotion, poor concentration, and fear of permanent symptoms. Dependent variables were parent reported psychosocial, physical, and total HRQOL. Separate multi-variable linear regression models controlling for age, sex, and concussion history were used to assess the association between EBS and HRQOL. Estimated adjusted mean differences (MD) and 95% confidence intervals (CI) were used to assess associations; MDs with a 95%CI excluding 0.0 were considered statistically significant. Overall, n = 245 presented to the study clinic three days post-concussion and completed the one-month follow-up (Mage = 14.28 ± 2.09 years, 59.02% male, 90.64% Caucasian, 31.84% with concussion history). At one-month post-concussion, adolescents with pre-concussion EBS levels had significantly lower psychosocial, physical, and total HRQOL than those with no EBS. In addition, those with EBS worse than pre-concussion had significantly lower psychosocial, physical, and total HRQOL than those with no EBS and EBS at pre-concussion levels. These findings highlight the importance of HRQOL assessments and that targeted interventions may be needed for those with EBS at one-month post-concussion to improve HRQOL.
