Functional Outcomes of Sleep Questionnaire
The Functional Outcomes of Sleep Questionnaire captures how sleepiness and sleep disruption affect daytime function. This page is for clinics. It is not a diagnosis and not a public test.
Overview
What is the FOSQ?
FOSQ focuses on functional impact rather than a single sleepiness total. Clinics use it to organise sleep-related function for clinician review, not as a stand-alone sleep-disorder diagnosis.
Development and clinical use
Weaver and colleagues published FOSQ to measure how sleepiness affects daily activities. Confirm current official materials, including which FOSQ version you intend, before a live pathway.

Administration
A focused client experience
FOSQ 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 FOSQ
These answers stay inside educational catalogue scope. They do not replace official manuals or clinician judgement.
Does FOSQ diagnose a sleep disorder?
No. It is a functional-impact self-report. Diagnosis remains a clinician task.
Can I complete FOSQ here?
No. This landing does not collect answers.
How is FOSQ used on Lirena?
As a sleep-intake self-report. Clinicians review domain patterns with sleep history.
Is FOSQ the same as ESS?
No. ESS asks about dozing likelihood. FOSQ asks how sleepiness affects function.
