MMPI correlates among post-acute TBI patients

A retrospective study examined predictors of MMPI responses for a sample of 66 post-acute traumatic brain-injured patients. Years of education was found to be correlated to four clinical scales and two validity scales with the more educated subjects reporting less psychopathological symptoms. Those with higher Verbal IQs tended to score higher on the Hysteria scale and the Repression scale. Those with higher Performance IQs were found to be endorsing more items on the Hypochondriasis, Hysteria and Organic Symptoms scales. The Verbal-Performance (V-P) difference score was not found to be significantly predictive of indices of defensiveness. Depression was found to vary over time peaking between 1 and 3 years after injury. The results were discussed in terms of their implications for clinicians.
