Event Title
Factor structure of the Beck Anxiety Inventory in mild traumatic brain injury
Project Type
Completed quantitative research study
Primary Department
Clinical Psychology
Description
Introduction: The factor structure of the BAI remains unknown for people with mild traumatic brain injury (mTBI), despite common anxiety symptoms in this group. Method: A sample of 141 individuals diagnosed with an mTBI were evaluated. Confirmatory factor analysis was used to test whether items loaded on a single anxiety factor, a two-factor structure, or a four-factor structure. Results: The best fit was the model with four factors consisting of cognitive, autonomic, neuromotor, and panic symptoms, CFI = .92; RMSEA=0.067, 90% CI (0.053, 0.081). Conclusion: Anxiety symptoms following mTBI can be evaluated based on cognitive, autonomic, neuromotor, and panic components.
