Objective: To examine resilience as a predictor of change in self-reported fatigue after mild traumatic brain injury (MTBI).
Participants: A consecutive series of 67 patients with MTBI and 34 orthopedic controls.
Design: Prospective longitudinal study.
Main Measures: Resilience Scale, Beck Depression Inventory-Second Edition, and Pain subscale from Ruff Neurobehavioral Inventory 1 month after injury and Barrow Neurological Institute Fatigue Scale 1 and 6 months after injury.
Results: Insomnia, pain, and depressive symptoms were significantly correlated with fatigue, but even when these variables were controlled for, resilience significantly predicted the change in fatigue from 1 to 6 months after MTBI. In patients with MTBI, the correlation between resilience and fatigue strengthened during follow-up. In controls, significant associations between resilience and fatigue were not found.
Conclusion: Resilience is a significant predictor of decrease in self-reported fatigue following MTBI. Resilience seems to be a relevant factor to consider in the management of fatigue after MTBI along with the previously established associated factors (insomnia, pain, and depressive symptoms).
