ObjectiveTo evaluate the trajectory of resilience during the first year following a moderate-severe TBI, factors associated with resilience at 3, 6 and 12-months post-injury, and changing relationships over time between resilience and other factors.DesignLongitudinal analysis of an observational cohort.SettingFive inpatient rehabilitation centers.ParticipantsPatients with TBI (N = 195) enrolled in the resilience module of the TBI Model Systems study with data collected at 3, 6, and 12-month follow-up.InterventionsNot applicable.Main Outcome MeasureConnor-Davidson Resilience Scale.ResultsInitially, resilience levels appeared to be stable during the first year post-injury. Individual growth curve models were used to examine resilience over time in relation to demographic, psychosocial, and injury characteristics. After adjusting for these characteristics, resilience actually declined over time. Higher levels of resilience were related to non-minority status, absence of pre-injury substance abuse, lower anxiety and disability level, and greater life satisfaction.ConclusionsResilience is a construct that is relevant to understanding brain injury outcomes and has potential value in planning clinical interventions.
