Personality inventory responses of males with medically intractable seizures.
The psychosocial adjustment of 50 male patients to intractable seizures was assessed by comparing their responses to a combined version of the Minnesota Multiphasic Personality Inventory (MMPI) and the California Psychological Inventory (CPI) to the responses of 50 medical, psychiatric, or nonclinical controls who denied seizures. The two groups were significantly different (p < .01) on one MMPI and 10 CPI scales. Significant (p < .01) between-group differences were also reflected in 29 of the 704 personality inventory items. Those items were rationally clustered according to content into six conceptually identifiable subscales; 30 additional items with similar content that were significant at the .05 level were added to those subscales. Comparison of subscale scores of an additional 30 seizure and 30 nonseizure subjects using analysis of variance revealed F values that reached statistical significance (p < .05) in four cases and approached significance (p = .07) in another. Applying coefficients derived from discriminant analysis of the first samples correctly classified 99% of the original patients and 85% of the validation subjects. Results reveal a logical, understandable, and largely adaptive response to intractable seizures and offer little support for the concept of a dysfunctional or pathological interictal personality style.
