A-115 Predictors of Depressive Symptoms in Adolescent Patients Following Concussion
Abstract Objective The present study sought to examine specific predictors and factors associated with depressive symptoms at initial(V1) and subsequent(V2) visits following concussion in adolescents. Methods This study enrolled adolescents aged 10–18 (14.5 ± 2.2 years) within 30 days of a diagnosed concussion. Patients completed Mood and Feelings Questionnaire-Short-Child Report (MFQC), Postconcussion Symptom Scale (PCSS), neurocognitive testing(ImPACT), and Vestibular-Ocular Motor Screening. Logistic regression (LR) analyses evaluated risk factors and clinical presentation as predictors of post-injury MFQP scores above a cutpoint of 8. Results Participants included 113 adolescents (50.4% male; 77% sport-related) who presented for V1 8.9 ± 6.2 days post-injury and V2 18.43 ± 11.9 days after V1. Overall, 5.3% reported pre-injury depression and 15.8% reported post-injury depressive symptoms above clinical cutoff on the MFQC. The LR model predicting increased depressive symptoms at V1 was significant (R2 = 45.0%, p = .007), supporting post-traumatic amnesia(PTA; OR = 3.15, 1.01–9.88) as a predictor. The LR model predicting depressive symptoms at V2 was significant (R2 = 62.2%, p = .021), supporting history of depression(OR = 25.5, 3.86–168.2) as the only significant predictor. Those scoring above 8 on the MFQC at V1 were more likely to have a prolonged recovery(over 30 days; OR = 10.4, 1.29–83.6). Conclussions The primary findings indicated that PTA was associated with increased depressive symptoms earlier, whereas a history of depression was associated with increase depressive symptoms later following concussion. Patients scoring higher on depressive symptoms were 10 times more likely to have a prolonged recovery. Together, these findings highlight the importance of evaluating depressive symptoms and factors that are associated with these symptoms to inform prognosis and earlier treatment for depressive symptoms following concussion.
