Psychometric Validation and Revision of the Common Misconceptions About Traumatic Brain Injury Scale

This study examined the factor structure and validity of the 40-item CM-TBI scale using 988 international participants and identified significant psychometric limitations, resulting in a revised 18-item instrument with improved validity. The authors conclude that modern understanding of TBI has evolved since the original scale's development, and recommend developing new instruments that more clearly distinguish between knowledge and misconceptions as separate constructs.
