Sleepgenic uses questionnaires at the Clinical Signal Boundary: after wearable patterns or symptoms create a question, but before any diagnostic conclusion. The correct tool depends on the question. Official links preserve the validated wording, scoring, translations, and copyright conditions.
Sleepgenic does not reproduce the instruments, store responses, or combine them into a Sleepgenic diagnostic score.

The common mistake is treating every questionnaire as a general “sleep test,” combining their scores, or using one instrument to answer a question it was not designed to address. Screening tools organize risk and symptoms. They do not replace clinical diagnosis.
Sleep questionnaires are not interchangeable. Each was developed to assess a particular domain: broad sleep quality, athlete-specific sleep difficulty, daytime sleepiness, obstructive sleep-apnea risk, or insomnia severity.
The right instrument is the one designed for the question you are actually asking. A score outside that domain can create false reassurance or unnecessary alarm.
The Pittsburgh Sleep Quality Index assesses multiple dimensions of sleep quality over a one-month interval. It is useful when the question is broad: “Has my sleep generally been poor or disrupted?” It is not an apnea diagnostic test and should not be altered to use a different recall period.
The University of Pittsburgh permits free linking in educational programs but controls reproduction, modification, clinical use, and commercial use. Sleepgenic therefore links to the official source rather than embedding the questionnaire. Official PSQI information →
The Athlete Sleep Screening Questionnaire was designed for athletes and includes concerns that general sleep questionnaires may not capture as well, including training schedules, travel, chronotype, sleep difficulty, and sleep-disordered breathing.
This is the most directly relevant instrument for the TrailGenic–Sleepgenic intersection. The Centre for Sleep & Human Performance offers an official online version with personalized recommendations. Sleepgenic links to that version and does not mirror its questions. Official ASSQ →
The Epworth Sleepiness Scale asks about the likelihood of dozing in ordinary situations. It measures daytime sleepiness—not sleep quality, insomnia severity, or apnea itself. Someone can have disrupted sleep without a high ESS score, and a high score does not identify the cause.
The ESS is copyrighted and requires a license to use, even where no license fee applies. Sleepgenic provides only the official licensing and information link. Official ESS licensing →
STOP-Bang is a concise obstructive sleep-apnea risk screener. It was originally developed in perioperative populations and has since been evaluated in broader settings. It screens for obstructive sleep apnea—not central sleep apnea—and does not replace polysomnography or an appropriate home sleep-apnea test.
The tool is owned by its developers and University Health Network, with permission and licensing pathways for different uses. Sleepgenic links to the official tool without reproducing it. Official STOP-Bang screening page →
The Insomnia Severity Index evaluates perceived difficulty initiating or maintaining sleep, satisfaction with sleep, daytime interference, noticeability, and distress. It is used for screening and tracking treatment response, but its official source states that it is not intended as a stand-alone diagnostic tool.
The ISI is distributed by Mapi Research Trust on behalf of its copyright holder. Sleepgenic links to the official information and request process. Official ISI information →
A questionnaire becomes relevant when wearable data or lived symptoms create a specific question. Poor month-long sleep quality points toward PSQI. Athlete-specific sleep concerns point toward ASSQ. Daytime dozing points toward ESS. Obstructive apnea risk points toward STOP-Bang. Perceived insomnia severity points toward ISI.
No questionnaire should be used to overrule symptoms, replace medical evaluation, or generate a Sleepgenic diagnosis. The American Academy of Sleep Medicine recommends that questionnaires and prediction algorithms not be used to diagnose obstructive sleep apnea without appropriate sleep testing.
Sleepgenic intentionally does not reproduce the item text, scoring worksheets, translations, or branded forms. It does not collect or retain responses. Direct official links preserve the validated instrument and its current conditions of use.
Use a screener to organize the question. Use clinical evaluation to answer it.
Sleepgenic’s dataset can identify a recurring wearable pattern—for example, oxygen disruption, fragmentation, or duration–recovery divergence—but it cannot determine whether the pattern represents insomnia, sleep-disordered breathing, insufficient sleep opportunity, or another condition.
A domain-matched screener can help organize the next question. It does not convert the n=1 wearable record into a diagnosis.
