Abstract

Sleep problems are common among nursing students, yet the psychometric performance of widely used measures remains underexamined. The Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) are frequently applied to assess sleep quality and daytime sleepiness, respectively, but evidence of their validity and reliability in nursing-student populations is limited.
