Pediatric Daytime Sleepiness Scale

PDSS (Pediatric Daytime Sleepiness Scale) is a widely used tool for assessing daytime sleepiness in children and adolescents. It contains 8 items with a total score of 0–32.

What this scale measuresThe PDSS is self-rated by the adolescent over the past month and covers dozing off in class, while studying, doing homework, riding in a car, watching TV, after lunch, struggling to stay awake, and daytime naps. Higher scores may indicate insufficient sleep, sleep-disordered breathing or narcolepsy and warrant timely evaluation at a pediatric sleep center.
