Web-Based Psychoeducational Intervention for Postconcussion Symptoms: A Randomized Trial

The objective of this study was to investigate the effectiveness of a web-based educational intervention for reducing postconcussion symptoms. 158 participants with self-reported symptomatic mild traumatic brain injury were randomized to intervention versus control. There was no effect of intervention on symptom severity or attributions. Subgroup analyses suggested benefit of the web-based intervention in those receiving concurrent mental health treatment and in those participants with the greatest time since injury (>1 year after mild traumatic brain injury). Web-based educational intervention was not effective overall in this sample. However, there is some suggestion of promise in those receiving concurrent mental health treatment and with more chronic symptoms. Findings also suggest potential benefit of interventions targeting self-efficacy.
