Abstract
OBJECTIVE: We sought to determine if we could reduce symptoms of depression in individuals with a traumatic brain injury usingmindfulness-based cognitive therapy. SETTING: The study was conducted in a community setting. PARTICIPANTS: We enrolled adults with symptoms of depression after a traumatic brain injury. DESIGN: We conducted a randomized controlled trial; participants were randomized to the 10-week mindfulness-based cognitive therapy intervention arm or to the wait-list control arm. MAIN MEASURES: The primary outcome measure was symptoms of depression using the Beck Depression Inventory-II. RESULTS: The parallel group analysis revealed a greater reduction in Beck Depression Inventory-II scores for the intervention group (6.63, n = 38,) than the control group (2.13, n = 38, P = .029). A medium effect size was observed (Cohen d = 0.56). The improvement in Beck Depression Inventory-II scores was maintained at the 3-month follow-up. CONCLUSION: These results are consistent with those of other researchers that use mindfulness-based cognitive therapy to reduce symptoms of depression and suggest that further work to replicate these findings and improve upon the efficacy of the intervention is warranted.
