What is it about?

We used a statistical technique called cluster analysis to identify different subtypes of subjective symptom reports on a comprehensive personality inventory in persons with traumatic brain injury. We found that the subtype that reported the most problems had primarily uncomplicated mild injuries, and had a large proportion of persons with complicating factors (e.g., past physical or sexual abuse) before the brain injury.

Why is it important?

Our findings indicate that subjective symptoms after a traumatic brain injury cannot be routinely and automatically attributed to that brain injury. Pre-existing complicating histories play a major role.


This is the first time anybody has looked at subtypes of MMPI-2-RF profiles in a large clinical sample with a broad range of injury severity, and not just primarily people involved in financial compensation-seeking. For that reason, the paper makes a new contribution to the literature.
