The Effect of Night Study Patterns on Academic Performance among Medical Students: Scoping Review

This project aims to systematically map and synthesize the available scientific evidence on the relationship between night study patterns, sleep deprivation, chronotype, and academic performance among medical students. The review follows the methodological framework proposed by Arksey and O’Malley, enhanced by Levac et al., and adheres to the PRISMA-ScR reporting guidelines. The search strategy includes PubMed/MEDLINE, Web of Science, ScienceDirect, Google Scholar, and Europe PMC, covering literature published between January 2000 and December 2025. The review explores conceptual definitions, methodological diversity, measurement instruments (e.g., PSQI, ESS), and academic performance indicators (e.g., GPA, exam scores). A descriptive critical appraisal using STROBE, NOS, AMSTAR 2, and GRADE was conducted for contextual interpretation; however, quality assessment was informational and non-exclusionary. The objective is to identify research trends, methodological gaps, and evidence patterns to inform future longitudinal studies and targeted educational interventions.
