To investigate the symptom trajectories of depressive and post-concussive symptoms (PCS) in slow-to-recover adolescents to understand how the two sets of symptoms are related.We used data from a randomized clinical trial of a collaborative care intervention for post-concussive symptoms to better understand how these two sets of symptoms change in parallel over 6 months.PCS and depressive symptom scores for 49 adolescents (ages 11-17) were measured at enrolment and after 1, 3, and 6 months. Latent growth curve modelling for parallel processes was used to simultaneously examine change in PCS and depressive symptoms over time and to evaluate the influence of one change process on the other.On average, patients enrolled 66 days following injury (Interquartile range (IQR) 43.5, 88.5). PCS and depressive symptoms were significantly associated at enrolment and over time, and both decreased over the course of 6 months. Higher PCS at enrolment predicted a greater decrease in depressive symptoms over time.Our results suggest that clinicians should screen for and treat depressive symptoms in patients with high post-concussive symptoms one month following injury.
