        abstract = {Adolescent sleep disruption has become a significant public-health concern, driven by biological circadian shifts, academic pressures and increasing evening screen use. This study investigates the relationships between bedtime patterns, screen exposure after 20:00, sleep duration, daytime sleepiness and mental-health indicators among 53 students aged 14–18 from a school in Doha, Qatar. A cross-sectional survey was administered, collecting detailed data on sleep timing, sleep latency, nighttime awakenings, weekend schedule variability, screen exposure characteristics, caffeine intake, daytime fatigue, cognitive functioning and PHQ-2 depressive symptoms. Results indicate that students averaged fewer than 7 hours of sleep on school nights with later bedtimes and longer screen use significantly correlating with reduced sleep duration and poorer sleep quality. Higher evening screen use was also associated with increased daytime sleepiness and fatigue. Preliminary regression models suggest that screen hours after 20:00 and prolonged sleep latency are the strongest predictors of reduced sleep duration. PHQ-2 scores showed mild elevation in students reporting the shortest sleep durations. These findings highlight the need for targeted interventions, including reduced pre-bedtime screen exposure, sleep-hygiene education and school-level awareness programs. The study contributes preliminary evidence from a Middle Eastern adolescent population, an underrepresented region in sleep-health literature.},
