Preliminary Validation of the Epileptic Seizure Trigger Questionnaire for Adults with Epilepsy

This cross-sectional study validated a self-report questionnaire (EST-Q) to assess perceived seizure triggers in 100 adults with epilepsy from Brazil. The seven-item core module showed adequate internal consistency for group-level research but insufficient reliability for individual clinical decisions, with exploratory factor analysis supporting a predominantly unidimensional structure.
