The contribution of spirituality to quality of life in focal epilepsy.

People with epilepsy of comparable severity may differ widely in quality of life (QOL), suggesting a role for unexplored individual aspects. This study considered the possible role of spirituality. Thirty-two patients with focal epilepsy completed scales for QOL (World Heath Organization QOL, WHOQOL 100), spirituality (WHO Spirituality, Religiousness, and Personal Beliefs), depression, anxiety, and cognitive efficiency, as well as neuropsychological testing. The QOL and spirituality scales exhibited satisfactory internal consistency. Factor analyses of the scale and test scores yielded separate spiritual (Personal Meaning, Inner Energy, Awe and Transcendence, and Openness), affective (Mood), and cognitive (Cognition, Memory, and Perceived Cognitive Efficiency) factors. The total WHOQOL 100 score was significantly predicted by the Awe and Transcendence and Mood factors. The spiritual, Mood, and Cognition factors significantly predicted single QOL domains. These preliminary results highlight the contribution of spirituality to QOL in epilepsy, encouraging future studies. This could influence the conceptualization and assessment of QOL in these patients.
