Revisiting the Common Misconceptions About Traumatic Brain Injury Scale (CM-TBI); What Does It Really Measure?

There is no psychometric support for the current structure of the CM-TBI. This is likely due to changes in understanding of TBI since the scale's inception, and issues of conceptual ambiguity. It is also proposed that a distinction must be made between knowledge and misconceptions, as these are 2 related but different constructs that are not clearly delineated in the current CM-TBI. Using the revised scale here offers researchers a more modern, focussed, and valid measure, but a new scale to measure knowledge and misconceptions in TBI is urgently needed.
