Sleep Quality Test
Look at the quality of your main sleep period over the past month, including settling, duration, interruptions, and daytime effects. Eighteen original adult questions provide an educational breakdown, an instant result, and an optional PDF copy.
Sleep Quality Test is a free, confidential 18-question self-assessment, original items · Six sleep-quality areas. 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.
A fuller description of your sleep
Sleep quality is more than the number of hours you spend in bed. This questionnaire separates six experiences that can help you describe a sleep concern more clearly.
A pattern across sleep areas
Subjective quality, time to fall asleep, duration, efficiency, disturbances, and daytime dysfunction receive three items each. These are our educational groupings, not validated subscales. The breakdown helps distinguish what feels unsatisfactory from what specifically happens.
Your main sleep period
Answer for the past month using your main sleep period, even if you work nights. The questions concern perceived difficulty, not an ideal bedtime. Your work, caring responsibilities, environment, and health can affect the pattern.
Descriptions you can discuss
Original frequency questions let you organize observations without claiming to measure brain activity or calculate sleep efficiency. A low total cannot rule out sleep apnea, and a high total cannot identify the right treatment without more assessment.
| Feature | Typical free quiz | Psychology.com |
|---|---|---|
| Scope | May focus only on sleep duration | Six educational areas with three items each |
| Instrument identity | May label new questions a PSQI test | Original questions, explicitly not the PSQI |
| Efficiency | May confuse time in bed with sleep | Perceived wakefulness, not a calculated percentage |
| Scoring | May borrow established instrument thresholds | Educational thirds of a 0 to 54 total |
| Schedules | May assume everyone sleeps at night | Instructions accommodate the main sleep period |
| Next steps | May provide sleep hygiene as the only answer | Medical assessment and CBT-I context when appropriate |
How scoring works
Answers are scored 0–54 in total. Your result falls into one of 3 bands:
| Score | Band | What it suggests |
|---|---|---|
| 0–17 | Less frequent sleep difficulties | These sleep difficulties were less frequent across the month you described. |
| 18–35 | Recurring sleep difficulties | Several sleep-quality problems were recurring features of your month. |
| 36–54 | Frequent sleep difficulties | Many areas of sleep appear disrupted, with possible effects on daily life. |
Methodology & sources
This questionnaire covers broad areas commonly considered in sleep assessment and discussed in the Pittsburgh Sleep Quality Index literature: subjective quality, time to fall asleep, duration, efficiency, disturbances, and daytime dysfunction. We wrote eighteen original statements, three in each area. This is not the PSQI and does not reproduce its questions, response anchors, component algorithm, or seven-component structure. We do not score a medication-use component. Our efficiency items describe perceived time awake within a sleep opportunity; they do not calculate the ratio of sleep time to time in bed. Our duration items describe perceived insufficiency rather than estimating hours. The domain labels organize reflection and must not be treated as validated subscales.
Adults rate how often each experience occurred across the past month, from Never, 0, to Almost always, 3. The eighteen responses sum to 0 to 54, and each domain contributes 0 to 9. Higher scores mean more reported sleep difficulty; no items are reversed. Bands of 0 to 17, 18 to 35, and 36 to 54 are educational thirds, not clinical cutoffs or PSQI categories. The questionnaire and interpretations are unvalidated and cannot establish insomnia, sleep apnea, or another sleep condition. Recall, opportunity to sleep, shift patterns, and recent illness can affect answers. A sleep diary and a clinical conversation can add timing and context that this questionnaire cannot supply.

Sleep Quality Test FAQ
Is this the PSQI test or Pittsburgh Sleep Quality Index?
No. The PSQI is a specific questionnaire with seven component scores and a global score from 0 to 21. This page has eighteen original items, six educational groupings, and a 0 to 54 total. Its score cannot be converted to a PSQI score. A similar topic and monthly timeframe do not make the two measures equivalent.
How is this different from the Insomnia Test?
Our <a href="/tests/insomnia">Insomnia Test</a> uses the Insomnia Severity Index to explore insomnia-related difficulty and impact. This page considers a broader set of sleep-quality experiences, including insufficient sleep opportunity and disturbances. You can have poor sleep quality for reasons other than insomnia. A clinician can help distinguish not getting enough opportunity to sleep from difficulty sleeping despite that opportunity.
How is sleep quality different from chronotype?
Chronotype concerns your tendency toward earlier or later sleep and activity. The <a href="/tests/chronotype">Chronotype Test</a> explores that preference. This page asks about the quality and impact of actual sleep. A later preference is not itself poor sleep, though a mismatch between your schedule and your sleep timing can be worth discussing.
Can it tell me whether I have sleep apnea?
No. Sleep apnea requires medical assessment and may require a sleep study. Loud snoring, breathing pauses noticed by someone else, gasping during sleep, or unexplained daytime sleepiness are reasons to speak with a physician, whatever this total shows. This questionnaire does not measure breathing or oxygen levels, and reassuring answers cannot exclude a sleep-related breathing problem.
What if I work nights or care for someone overnight?
Use your main sleep period even if it happens during daylight. Count difficulties caused by limited opportunity or interruptions as you experienced them, then keep that context in mind. The questionnaire cannot separate environmental barriers from a sleep condition. A practical account of your schedule can help a clinician suggest support that fits your actual responsibilities.
Should I change my medication or time in bed after taking it?
No. This score does not select a medication or prescribe a sleep schedule. Discuss medicines, alcohol, supplements, and daytime sleepiness with a clinician or pharmacist. CBT-I is an established treatment for chronic insomnia, but a tailored plan involves more than general sleep tips. Do not begin sleep restriction or change prescribed treatment solely because of this result.
