MMPI profiles of closed head trauma patients: impact of neurologic complaints.
The MMPI is used commonly with neurologic patients despite concerns about its validity with this population. The basis for this concern--possible artifactual effects due to neurologic-related MMPI items (NRIs)--was assessed in this study of 58 closed head trauma (CHT) patients. The MMPI profiles of these patients were analyzed before and after statistical correction was made for 42 NRIs that were identified by three neurologists. Significant effects occurred on Scales 1 (HS), 2 (D), 3 (HY), 7 (PT), and 8 (SC) in regard to their T scores, frequency of pathological elevation (T greater than 69), and representation in configural codes. The results suggest that MMPI content scales and subscales may help to distinguish the relative contribution of neurologic and emotional complaints on MMPI profiles.
