Daytime Sleepiness Test
Explore your tendency to doze during ordinary activities and the effects of sleepiness on your day. Twelve original adult questions give an educational summary and an optional PDF copy, with guidance on when to seek medical sleep assessment.
Daytime Sleepiness Test is a free, confidential 12-question self-assessment, original items · Daytime sleepiness. It takes about 5 minutes, runs entirely in your browser, and gives you a plain-language score across 3 interpretation bands plus an optional in-depth report. It is an educational screening, not a diagnosis.
Sleepiness is more specific than feeling tired
Sleepiness means a tendency to fall asleep; fatigue can involve low energy without that tendency. This page asks about dozing and its consequences while keeping medical causes in view.
Likelihood of dozing
Six original, everyday situations ask about drifting into sleep when you intend to stay awake. They avoid treating every low-energy feeling as sleepiness. Your estimate is subjective and depends partly on whether you have encountered the situation.
Effects on your day
Six further statements ask how often sleepiness interrupts activities or changes what you can do. This makes impact visible alongside propensity to doze. A low score in one area does not erase an important problem in the other.
A medical starting point
Our two equal-weight educational groupings help organize an account for a physician. They are not validated subscales or an Epworth score. Sleep apnea, narcolepsy, medications, and insufficient sleep are among the possibilities that require context, not assumptions.
| Feature | Typical free quiz | Psychology.com |
|---|---|---|
| What tired means | May combine low energy and sleepiness | Explicit focus on falling asleep and daily impact |
| Situations | May copy the Epworth list without a licence | Six original dozing situations |
| Impact | May give only a propensity score | Separate six-item impact section |
| Grouping | May imply validated clinical subscales | Our own equal-weight educational groupings |
| Thresholds | May reuse Epworth cutoffs | Educational thirds, no score conversion |
| Care pathway | May frame all sleepiness as emotional | Medical assessment and immediate safety advice |
How scoring works
Answers are scored 0–36 in total. Your result falls into one of 3 bands:
| Score | Band | What it suggests |
|---|---|---|
| 0–11 | Less reported sleepiness | Dozing tendency and its effects were limited in the situations described. |
| 12–23 | Recurring sleepiness or impact | Sleepiness appears noticeable enough to examine in a medical conversation. |
| 24–36 | Frequent sleepiness and impact | Your answers warrant a medical sleep evaluation, particularly if dozing is unintended. |
Methodology & sources
This original questionnaire covers two related topics: likelihood of unintended dozing and the daily impact of sleepiness. The first section contains six new everyday situations rated for the chance of drifting into sleep; the second contains six original impact statements rated for frequency. Both refer to your usual waking period over the past two weeks. This is not the Epworth Sleepiness Scale and does not reproduce its eight situations, response wording, scoring range, or cutoffs. Our Dozing likelihood and Daytime impact sections are educational groupings, not validated subscales. They are deliberately separated because imagining a chance of sleep and recalling actual disruption are different judgments, even though both help describe a sleepiness concern.
Each section contributes 0 to 18, with responses valued 0 to 3 and no reversed items. The primary total sums both sections, 0 to 36, giving equal weight to likelihood and impact. Bands of 0 to 11, 12 to 23, and 24 to 36 are educational thirds, not clinical cutoffs, fitness-to-drive categories, or Epworth equivalents. The questionnaire has not been validated, and its sensitivity to medical sleep disorders is unknown. Estimates for unfamiliar situations add uncertainty. The total cannot assess breathing during sleep, narcolepsy, medication effects, or safe alertness for a particular task. A single episode of dozing in an unsafe setting requires action regardless of score. Persistent unintended sleep warrants medical review.

Daytime Sleepiness Test FAQ
Is this the Epworth Sleepiness Scale?
No. The Epworth Sleepiness Scale is an established eight-situation measure of usual sleep propensity developed by Murray Johns. It is copyrighted and distributed under licence. This page uses twelve original questions across two different sections. Its 0 to 36 total is not an Epworth score, and you cannot apply published Epworth thresholds to the result.
How is sleepiness different from fatigue?
Sleepiness is the tendency to fall asleep. Fatigue can feel like low energy, physical heaviness, or mental exhaustion without actual dozing. They can occur together but suggest different questions for a clinician. The <a href="/tests/fatigue">Fatigue Test</a> explores energy and impact; this page focuses specifically on sleep tendency and its consequences during your intended waking time.
Does a high score mean sleep apnea or narcolepsy?
No. Both are medical conditions that can involve daytime sleepiness, but this questionnaire cannot determine either. A physician can review sleep opportunity, medicines, symptoms, and the need for sleep testing. Mention snoring, witnessed breathing pauses, or sudden sleep episodes if present. Seeking an evaluation is appropriate when dozing is persistent or disruptive, without assuming a specific cause.
What if I have not been in one of the situations?
Estimate from a similar quiet activity during the past two weeks, without deliberately testing your alertness. Your result will be less certain for situations you have not experienced. Tell a clinician which answers were estimates if you share the result. The impact section should reflect events that actually occurred rather than what you fear could happen.
Is my score low enough that I can drive?
No score here can clear you to drive. Do not drive or operate machinery when you feel sleepy or are struggling to stay awake. If drowsiness develops while driving, stop somewhere safe and arrange an alternative. Report unintended sleep or a near miss to a medical professional promptly, even if your total is in the lowest band.
Should I take the sleep quality or insomnia test too?
The <a href="/tests/sleep-quality">Sleep Quality Test</a> looks at a month of sleep experiences. The <a href="/tests/insomnia">Insomnia Test</a> focuses on insomnia severity. Those pages may help describe context, but completing more quizzes is not necessary before seeing a physician. Persistent daytime sleepiness deserves attention even when you think you sleep well.
