Preliminary development and validation of the Indonesian Pediatric Epilepsy Questionnaire (INA‐PEPSI) to determine epilepsy and distinguish focal and generalized epilepsy in infants and children with unprovoked seizure in low‐resource settings

Objective To outline the preliminary development and validation of a questionnaire for diagnosing epilepsy and distinguishing focal and generalized epilepsy among infants and children in Indonesia, where electroencephalography and pediatric neurologists are generally not available. Methods A 10‐question questionnaire comprising of 43 items was developed through literature review and expert panel discussions. Then, the questionnaire was administered by pediatricians to 75 children aged 1 month to 18 years old presenting with >1 episode of unprovoked seizures at an interval of >24 h. Subsequently, the questionnaire was assessed for content validity with item‐level and scale‐level content validity indices and ratio, construct validity with item‐total correlation tests, criterion validity with diagnostic parameter assessments, and inter‐rater reliability using Cohen's kappa (κ) and internal consistency with Cronbach's alpha (α) coefficient. Results The questionnaire exhibited favorable internal validity and reliability in diagnosing epilepsy and distinguishing focal and generalized epilepsy, with excellent content (both indices and ratio at 1) and construct validity (rcount > rtable at p
