In this episode, Dr. Scott Sperling and student leader, Dr. Elaine Schultz, discuss the article Psychometric properties of two instruments assessing catastrophizing and fear-avoidance behavior in mild traumatic brain injury with two of the paper’s authors, Skye King and Dr. Melloney Wijenberg. This study aimed to invesigate the factor structure, internal consistency, test-restest reliability, and concurrent and construct validity of the Postconcussion Symptom Catastrophizing Scale (PCS-CS) and the Fear of Mental Activity Scale (FMA) in a sample of participants with mild TBI compared to orthopedic injury and healthy adults. The sample was comprised of 185 mTBI participants, 180 with orthopedic injury, and 116 healthy adults. Findings supported a three-factor model (magnification, rumination, helplessness) with a higher order factor (catastrophizing) for the PCS-CS and a two-factor model (activity avoidance and somatic focus) for the FMA. Results supported strong internal consistency, test-retest reliability, and convergent validity. Overall, this study provided evidence of psychometric strength for these measures and support their use in research and cllinical practice in mTBI to better understand prolonged recovery.
