A longitudinal study of the effects of seizure symptoms on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical interpretation.

This study investigated whether the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) items reflecting seizure symptoms spuriously inflate MMPI-2 scores in persons with epilepsy. In a repeated measures prospective design, patients with epilepsy completed the MMPI-2 prior to epilepsy surgery and again two years later when they were either seizure-free or not seizure-free. Compared to baseline scores, only seizure-free patients showed a decline in endorsement of seizure items, and only on one scale, Hypochondriasis (Hs).
