title: The reliability and validity of the Revised Liverpool Impact of Epilepsy Scale for use in people with new-onset epilepsy.
abstract: The Impact of Epilepsy Scale was designed to assess the perceived impact of epilepsy on a number of different aspects of daily life. Following criticisms of the scale's content and focus, it was revised to incorporate an amended response continuum and additional items. A total of 1534 people with epilepsy completed the revised scale, along with other quality-of-life (QOL) measures, as part of the Standard and New Antiepileptic Drugs (SANAD) trial (Marson et al., 2007a,b) [9,10]. The revised scale had good reliability (internal consistency alpha coefficient of .83) and acceptable validity (concurrent and known-groups). Floor and ceiling effects were negligible. Therefore, the Revised Liverpool Impact of Epilepsy Scale is a reliable and valid instrument for assessing the perceived impact of epilepsy in people with new-onset epilepsy.
