Pittsburgh Sleep Quality Index
The Pittsburgh Sleep Quality Index is a self-report of recent sleep quality and disturbance. This page is for clinics. It is not a sleep-disorder diagnosis and not a public test.
Overview
What is the PSQI?
The PSQI covers several sleep-quality domains rather than a single dozing question. Clinics use it to organise sleep-history collection. It does not replace a sleep study, insomnia diagnosis, or medical review.
Development and clinical use
Buysse and colleagues published the PSQI as a sleep-quality instrument for clinical and research use. Later work has examined components and global scores. Confirm current official materials before using it in a live pathway.

Administration
A focused client experience
PSQI is completed as a focused self-report and stored for clinician review. This public page does not collect answers or return a score.
- One question at a time with visible progress
- Large keyboard-operable response choices
- Previous, next, and answer-review steps
- Clear confirmation that results go to the clinic

Report showcase
Designed to make evidence easy to review
The downloadable synthetic example illustrates report layout using invented response patterns, without patient data or instrument questions.
- Named instrument, version, and provenance
- Item-level response pattern without source wording
- Methodology, references, and clinical boundary
- Responsible clinician review rather than automated conclusions
Clinician review required
Methodology
Understand the measure and its scoring conventions
Published scoring conventions may exist in official materials. This public page does not independently verify scoring, cutoffs, or a production scoring rule. Use the official form and scoring instructions for the version you intend to use.

Questions
What clinics ask before they evaluate the PSQI
These answers stay inside educational catalogue scope. They do not replace official manuals or clinician judgement.
Is PSQI a sleep-apnoea test?
No. It is a sleep-quality self-report. Diagnosis of a specific sleep disorder remains a clinician task and may require investigation.
Can I complete PSQI here?
No. This landing does not collect answers or return a score.
How is PSQI used on Lirena?
As a sleep-intake self-report. Clinicians review domain patterns with history rather than treating a global score as a diagnosis.
Is ESS the same as PSQI?
No. ESS asks about daytime dozing. PSQI asks about sleep quality and disturbance. They answer different clinical questions.
