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 Total ESS = 5 out of 24 Passive situations: 1+1+0+2+1 = 5/15 Active situations: 0+0+0 = 0/9 Classification: Normal (0-10) The 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 Total ESS = 16 out of 24 Passive situations: 3+2+2+3+2 = 12/15 Active situations: 2+1+1 = 4/9 Classification: Moderate Excessive Sleepiness (15-17) With 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 are normal sleep requirements for children and adolescents?
Sleep requirements vary significantly by age group according to the American Academy of Sleep Medicine consensus recommendations. Infants aged 4 to 12 months need 12 to 16 hours including naps, toddlers aged 1 to 2 years need 11 to 14 hours, preschoolers aged 3 to 5 need 10 to 13 hours, school-age children aged 6 to 12 need 9 to 12 hours, and teenagers aged 13 to 18 need 8 to 10 hours per night. Many children and especially adolescents chronically sleep less than recommended, with studies showing that over 70 percent of high school students get less than 8 hours on school nights. Insufficient sleep is the most common and most preventable cause of excessive daytime sleepiness in the pediatric population.
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.
How does sleep apnea in children differ from adults?
Pediatric obstructive sleep apnea (OSA) differs from adult OSA in several important ways. The primary cause in children is adenotonsillar hypertrophy (enlarged tonsils and adenoids), whereas in adults it is typically obesity and upper airway soft tissue collapse. Diagnostic AHI thresholds are much lower for children: an AHI of 1 or more per hour is considered abnormal, compared to 5 or more in adults. Children with OSA may not exhibit the classic symptoms of loud snoring and witnessed apneas; instead, they may present with behavioral problems, hyperactivity, poor school performance, bedwetting, mouth breathing, or failure to thrive. First-line treatment is adenotonsillectomy, which resolves OSA in approximately 75 to 80 percent of non-obese children, whereas CPAP is the primary treatment in adults.
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.
Should parents or children complete the questionnaire?
Both parent-proxy and child self-report approaches have demonstrated validity for the pediatric ESS, and the optimal approach depends on the child age and developmental level. For children aged 6 to 10, parent-proxy completion or parent-assisted completion is generally recommended because younger children may have difficulty accurately assessing their own sleepiness propensity. Children aged 11 to 16 can typically complete the questionnaire independently with reliable results. Research shows moderate correlation between parent and child reports, with parents sometimes underestimating or overestimating sleepiness compared to the child self-report. Having both parent and child complete the questionnaire separately and comparing results can provide the most comprehensive picture. Clinicians should note who completed the form when interpreting results.
How does daytime sleepiness affect academic performance?
Excessive daytime sleepiness has a profound impact on academic performance in children and adolescents. Sleep-deprived students demonstrate impaired attention, reduced working memory capacity, slower processing speed, and decreased executive function, all of which are essential for learning. Studies show that students who sleep less than 8 hours on school nights have grade point averages 0.4 to 0.6 points lower than well-rested peers. Sleepy students are more likely to fall asleep in class, miss school days, and have difficulty retaining information taught during the day. Memory consolidation, a critical process for learning, occurs primarily during deep sleep stages. Schools that have delayed start times to 8:30 AM or later have seen measurable improvements in attendance, grades, and standardized test scores.
When should a child be referred to a sleep specialist?
A referral to a pediatric sleep medicine specialist is recommended when the pediatric ESS score exceeds 10 and cannot be explained by insufficient sleep duration alone. Other indications for referral include persistent loud snoring occurring more than 3 nights per week, witnessed apneas or gasping during sleep, difficulty awakening in the morning despite adequate sleep duration, behavioral problems or declining school performance associated with sleepiness, a family history of narcolepsy or other sleep disorders, and suspected restless legs syndrome. If a child is sleeping the recommended hours for their age group yet still demonstrates excessive daytime sleepiness, this strongly suggests an underlying sleep disorder requiring specialist evaluation. The evaluation may include overnight polysomnography or the Multiple Sleep Latency Test.
What is the role of school start times in pediatric sleepiness?
School start times play a critical role in adolescent sleep patterns and daytime sleepiness due to the biological shift in circadian rhythm that occurs during puberty. During adolescence, melatonin onset shifts approximately 2 hours later, making it biologically difficult for teenagers to fall asleep before 11 PM. When combined with early school start times of 7:00 to 7:30 AM, this creates chronic sleep deprivation. The American Academy of Pediatrics, the American Medical Association, and the Centers for Disease Control and Prevention all recommend that middle and high schools start no earlier than 8:30 AM. Research from districts that have implemented later start times shows average increases of 25 to 50 minutes of sleep per night, significant reductions in ESS scores, decreased drowsy driving accidents, and improvements in attendance and academic achievement.
