Abstract: | Summary: We assessed 77 candidates for epilepsy surgery to determine the association among neuroticism (a dimension of personality characterized by chronic negative emotions and behaviors), psychosocial adjustment as measured by the Washington Psychosocial Seizure Inventory (WPSI), and health-related quality of life (HRQOL) as measured by the Epilepsy Surgery Inventory 55 (ESI-55). Minnesota Multiphasic Personality Inventory 2 (MMPI-2) Neuroticism scale scores were significantly correlated with many domains of patient-perceived psychosocial adjustment and HRQOL regardless of frequency or type of seizures. We then followed 45 of the patients who subsequently underwent epilepsy surgery to determine the influence of neuroticism on postoperative functioning. Two-way analysis of variance (ANOVA) indicated that patients with high preoperative neuroticism had significantly poorer postoperative psychosocial adjustment and HRQOL scores than patients who had low or moderate preoperative neuroticism scores. These results support the validity of the MMPI-2 as a useful measure of neuroticism. Preoperative neuroticism has an important influence on postoperative psychosocial adjustment and HRQOL that is independent of postoperative seizure outcome. Understanding the influence of personality variables, such as neuroticism, on psychosocial functioning both before and after epilepsy surgery is essential in managing intractable seizures. |
