Formula
ESS-CHAD Total = Sum of 8 situation scores (0-3 each, max 24)
The child or parent rates the likelihood of dozing in 8 common situations from 0 (never) to 3 (high chance). Total ranges 0-24. Normal: 0-10, Mild: 11-14, Moderate: 15-17, Severe: 18-24. Validated for ages 6-16.
Worked Examples
Example 1: Normal Sleepiness in a 10-Year-Old
Problem:A 10-year-old boy rates: Reading=1, TV=1, Classroom=0, Car passenger=0, Lying down=2, Talking=0, After lunch=1, In traffic=0. Calculate pediatric ESS.
Solution:Situation scores: 1 + 1 + 0 + 0 + 2 + 0 + 1 + 0 = 5\nTotal ESS = 5 out of 24\nPassive situations: 1+1+0+2+1 = 5/15\nActive situations: 0+0+0 = 0/9\nClassification: Normal (0-10)\nThe child has appropriate daytime alertness for age.
Result:ESS-CHAD Score: 5/24 | Normal Daytime Sleepiness | No further evaluation needed
Example 2: Sleepy Adolescent Screening
Problem:A 14-year-old girl with declining grades and snoring rates: Reading=3, TV=2, Classroom=2, Car=2, Lying down=3, Talking=1, After lunch=2, Traffic=1. Calculate pediatric ESS.
Solution:Situation scores: 3 + 2 + 2 + 2 + 3 + 1 + 2 + 1 = 16\nTotal ESS = 16 out of 24\nPassive situations: 3+2+2+3+2 = 12/15\nActive situations: 2+1+1 = 4/9\nClassification: Moderate Excessive Sleepiness (15-17)\nWith snoring and declining academics, sleep study indicated.
Result:ESS-CHAD Score: 16/24 | Moderate Excessive Sleepiness | Referral to sleep medicine recommended
Frequently Asked Questions
What is the Pediatric Epworth Sleepiness Scale (ESS-CHAD)?
The Pediatric Epworth Sleepiness Scale, also known as the ESS-CHAD (Epworth Sleepiness Scale for Children and Adolescents), is a modified version of the adult Epworth Sleepiness Scale adapted for use in children and teenagers aged 6 to 16 years. Developed to address the limitations of applying adult-oriented sleepiness questions to younger populations, it uses age-appropriate language and situations that children commonly encounter. Like the adult version, it consists of 8 items rated from 0 to 3, producing a total score from 0 to 24. The questionnaire can be completed by the child alone, with parental assistance, or by parents reporting their observations of the child. It takes approximately 3 to 5 minutes to complete.
How does the pediatric ESS differ from the adult version?
While the pediatric ESS maintains the same 8-item structure and 0-3 scoring system as the adult version, several key modifications make it appropriate for younger populations. The language is simplified to be understandable by children as young as 6 years old. Some situation descriptions are adapted to be more relevant to children, such as referencing classroom settings instead of work meetings. The validation studies were conducted specifically in pediatric populations, and the normative data and cutoff scores have been established for children. Parents can serve as proxy respondents for younger children who may have difficulty with self-assessment. The scoring thresholds remain similar to the adult version, though some researchers suggest lower cutoffs may be more appropriate for children.
What causes excessive daytime sleepiness in children?
The most common cause of excessive daytime sleepiness in children is insufficient sleep due to late bedtimes, early school start times, screen use, extracurricular activities, and homework demands. Obstructive sleep apnea, primarily caused by adenotonsillar hypertrophy, affects 1 to 5 percent of children and causes fragmented sleep with repeated awakenings. Narcolepsy, though rare, typically presents in childhood or adolescence with severe daytime sleepiness, sometimes with cataplexy. Restless legs syndrome and periodic limb movement disorder can disrupt sleep quality without the child being aware. Psychiatric conditions including depression, anxiety, and ADHD frequently co-occur with sleep disturbances. Medications, particularly antihistamines and some ADHD treatments, can also contribute to daytime sleepiness.
Can screen time affect a child sleepiness score?
Screen time has a significant impact on pediatric sleep quality and can directly influence ESS scores. Blue light emitted by phones, tablets, and computers suppresses melatonin production by up to 50 percent, delaying sleep onset by 30 to 60 minutes. The stimulating content of games, social media, and videos increases physiological arousal, making it harder to fall asleep. Studies show that children with a screen in their bedroom sleep 20 to 30 minutes less per night than those without. The American Academy of Pediatrics recommends no screens for 30 to 60 minutes before bedtime and removing electronic devices from the bedroom. Children who exceed 2 hours of recreational screen time daily have a 60 percent higher risk of insufficient sleep. Reducing evening screen exposure often produces measurable improvements in daytime alertness.
