Epidaily, a scale for comprehensive functional assessment of patients with epilepsy.

Abstract Objective To develop and validate an epilepsy-specific scale for comprehensive functional assessment of patients with epilepsy, named Epidaily. Methods The multidisciplinary research group created through brainstorming a list of 47 items to explore the cognitive, social, basic and instrumental functionality of the patient. A group of epilepsy experts independent of the research group evaluated the suitability of all the items, which then were selected and reviewed by the research group to conform the Epidaily scale. On a sample of 102 patients, a reliability analysis was performed, as well as a validation one using as reference scale the score on the Activities of Daily Living Questionnaire (ADLQ), which evaluates basic and instrumental functionality. Results Epidaily consisted of 10 items distributed in four dimensions, with a possible score from 0 to 100 (perfect functionality). Inter-observer reliability was excellent, with an intraclass correlation coefficient of 0.98 (95% confidence interval 0.97–0.99). Criterion validity was demonstrated by the high positive correlation of the Epidaily score with the ADLQ score (Spearman’s rho coefficient 0.85, p  Significance Epidaily is a brief and versatile scale, with excellent inter-observer reliability, which has been validated for comprehensive functional assessment of patients with epilepsy.
