Metacognitive Therapy for People Experiencing Persistent Post-Concussion Symptoms Following Mild Traumatic Brain...

Area of Science:

• Neuroscience
• Psychology
• Rehabilitation

Background:

• Mild traumatic brain injury (mTBI) can lead to persistent post-concussion symptoms (PPCS).
• PPCS significantly impact quality of life, including headaches, cognitive deficits, and fatigue.
• Existing treatments for PPCS have varying degrees of efficacy, necessitating novel therapeutic approaches.

Purpose of the Study:

• To investigate the effects of metacognitive therapy (MCT) on PPCS.
• To assess MCT's impact on maladaptive coping strategies post-mTBI.
• To examine changes in positive and negative metacognitive beliefs following MCT.

Main Methods:

• A preliminary study employed a pre-post design with single-case A-B replication series.
• Nine participants diagnosed with mTBI and experiencing PPCS received MCT.
• Outcome measures included PPCS severity, coping strategies, and metacognitive beliefs.

Main Results:

• All nine participants demonstrated a reduction in PPCS, with eight showing reliable improvement.
• Moderate to very large effect sizes were observed for decreases in maladaptive coping and metacognitive beliefs.
• Some participants exhibited baseline trends that may have influenced intervention effects, warranting cautious interpretation.

Conclusions:

• MCT is associated with significant improvements in PPCS and psychological mechanisms following mTBI.
• The findings suggest MCT may be a viable therapeutic option for mTBI recovery.
• Further research, including randomized controlled trials, is recommended to confirm these preliminary results.
