In the hour before bed, what's the honest, typical picture of your screens and lighting?

I keep it flexible — I don't clamp down on screens, and I trust myself to wind down naturally whenever it happens

I mostly keep screens on but try to dim them or switch to night mode

I mostly dim the lights and keep screen use brief, though not every night

I hold a fixed, screen-free wind-down hour every night, no exceptions

When you lie down to sleep, how often is your mind racing, planning, or unable to switch off?

Almost every night — I can't switch off

Rarely — my mind settles quickly

How consistent is the time it takes you to fall asleep from night to night?

Very unpredictable night to night

How much do you rely on sleeping in at weekends to 'catch up' on the week's sleep?

Heavily — I sleep in a lot at weekends

Think about your actual relationship with the alarm clock and the time you allow yourself in bed — what's the honest pattern?

I treat extra time in bed as wasted time — I set an early alarm and get up regardless of how I feel, because that's discipline

I usually let the alarm cut my sleep a bit short; hitting my schedule matters more to me than finishing the night

I mostly allow enough time, though I sometimes trim it for an early start

I protect enough time in bed that I wake up on my own, before the alarm

When you wake in the morning, how restored and refreshed do you genuinely feel?

Rarely — I wake groggy and unrested

How well do you retain things you learned or worked on the day before after a night's sleep?

It sticks — often clearer next day

Think about how much effort, if any, you put into your bedroom's temperature, darkness, and quiet — what's the honest picture?

I don't fuss over my sleep environment — no blackout curtains, white noise, or thermostat tweaks; I just sleep wherever I land, warm, bright, or noisy

I've made a couple of small efforts, but the room is still often warm, bright, or noisy

I've handled most of it, though a little light or noise still gets through

I've deliberately controlled temperature, darkness, and quiet — it's cool, dark, and undisturbed

How reliably do you get natural outdoor light in the first hour or two after waking?

Almost never — I stay indoors

Think about your actual caffeine habits — coffee, tea, energy drinks — across a typical day. What's the honest pattern?

I don't set a cut-off — I trust my body and have caffeine whenever I feel like it, even in the evening

I don't watch the clock closely; it often ends up being late afternoon

I generally stop by mid-afternoon, though I don't enforce it strictly

I hold a hard cut-off — caffeine only in the morning, none after

How large is the gap between when you'd naturally sleep and when your schedule forces you to?

Severe — I'm always fighting my clock

Little to none — they line up

Think about your honest relationship with caffeine as a tool to get through the day — what's the real pattern?

I lean on it hard and treat that as normal — pushing through with caffeine is just what getting things done looks like

I need it to function most days, though I don't think much about why

I use it to get going, but I could probably do without it

I don't really need it — I feel functional either way

How much does your mood, patience, or irritability suffer on a typical day?

Significantly — I'm short-fused most days

How often do you nod off unintentionally — in meetings, on transport, or during quiet tasks?

Frequently — I fight it off often

Answer for how you've actually slept this month, not your intended routine — the honest version is the useful one.

A structured self-reflection — not a diagnostic.

This assessment is a structured self-reflection tool and educational resource — it is not a validated diagnostic and is not a substitute for clinical evaluation. Every dimension insight references peer-reviewed literature for educational context only. If you have concerns about your health, consult a qualified professional. Self-report instruments of this kind have no validated retest interval; the four-to-six-week Second Reading is a sensible practice, not a clinical standard.

How this instrument works

This is a 20-item structured self-assessment of your sleep recovery weak points, read across 5 dimensions: Sleep Latency; Sleep Duration; Night-time Continuity; Schedule Timing; and Daytime Functioning. Each item is a concrete scenario with four forced-choice responses — no neutral midpoint, so every answer commits to a direction — and response order is shuffled on every run to vary position; this implementation has not been tested for bias reduction. 5 of the 20 items are reverse-keyed — the attractive-sounding response is the structurally weak one — with wording intended to challenge socially desirable framing; this design has not been tested for bias reduction.

Scoring combines an overall reading with a per-dimension profile. Cascade flags compare configured dimension totals with editorial thresholds. They do not establish a compound risk and may not reflect the item-level pattern. The result bands are editorial guidance, not clinical thresholds: they organise the reading, they do not describe.

Every dimension insight cites peer-reviewed literature, and most answer reveals do — 13 sources back this instrument, each with DOI metadata supplied at build time; source relevance and claim interpretation remain editorial judgments. Compiled by the High Performance Culture editorial team. Instrument v1.1 · August 2026.

The 5 editorial answer groups

Sleep Latency

Strength here looks like allowing time to wind down and going to bed when drowsy.

The vulnerable pattern: taking bright light, screens, or an active mind into bed and then waiting a long time to fall asleep.

Sample itemOn a typical night, how long does it take you to fall asleep after you turn the lights off and intend to sleep?

First structural move: If it is appropriate for you, try a 45–60 minute dim, lower-screen-light wind-down and note how long sleep onset feels. This questionnaire cannot predict the result.

Go deeperProtocol: The Sleep Optimisation Protocol →Glossary: Sleep onset latency →

Sleep Duration

Strength here looks like allowing a broadly consistent sleep opportunity within the adult consensus range.

The vulnerable pattern: allowing a short or highly variable sleep opportunity and relying on weekend catch-up.

Sample itemOn an average work night, how many hours of actual sleep do you get?

First structural move: If it fits your circumstances, set a reminder that allows an 8.5-hour sleep opportunity for one week and record what actually happens. Do not treat that duration as an individual prescription.

Go deeperGlossary: Sleep debt →Glossary: How sleep pressure builds →

Night-time Continuity

Strength here looks like describing sleep as mostly unbroken and the bedroom as comfortable, dark, and quiet.

The vulnerable pattern: describing frequent awakenings, unrestorative sleep, or an uncomfortable bedroom.

Sample itemHow often do you wake during the night, and how easily do you get back to sleep?

First structural move: Choose one bedroom condition to observe — light, noise, temperature, or phone use — and note night-time interruptions for a week. The result will not measure sleep stages.

Go deeperDeep dive: The Science of Deep Sleep →Glossary: The glymphatic system →

Schedule Timing

Strength here looks like keeping wake time fairly consistent, seeing morning light, and limiting late caffeine.

The vulnerable pattern: describing variable wake times, little morning light, or late caffeine.

Sample itemHow consistent is your wake-up time across the whole week, weekends included?

First structural move: If it is appropriate for you, keep one wake time for a week and note morning light exposure. This questionnaire cannot measure whether your body clock changes.

Go deeperDeep dive: How Your Circadian Clock Works →Glossary: Social jet lag →

Daytime Functioning

Strength here looks like reporting steady daytime alertness, mood, and limited reliance on stimulants.

The vulnerable pattern: reporting daytime sleepiness, mood dips, heavy stimulant reliance, or unplanned dozing.

Sample itemHow often do you feel genuinely sleepy or fight to stay alert during the day?

First structural move: Record daytime sleepiness, mood, stimulant use, and the previous night's sleep for a week. Seek qualified advice for persistent sleepiness or unplanned dozing rather than relying on this score for a cause.

Questions, answered

Is this a diagnosis?

No. This assessment is a structured self-reflection tool, not a validated clinical instrument. Its result bands are editorial guidance, not clinical thresholds — they organise your answers into a readable profile; they do not describe a condition. If you have concerns about your health or wellbeing, speak to a qualified professional.

How were the questions designed?

Each of the 20 items presents a concrete scenario with four graded responses and no neutral midpoint, so every answer commits to a lean. Items were authored against the peer-reviewed literature listed in the evidence file on this page, and citation metadata is supplied at build time; source relevance and claim interpretation remain editorial judgments. Response order is shuffled on every run to vary position; this implementation has not been tested for bias reduction.

What happens to my answers?

Assessment answers stay on this device. Unfinished progress expires after 30 days. A completed profile and optional comparison history remain until you delete local assessment data or clear browser data. If you opt into email, your email address is sent; item answers are not. If you share a result link, total and dimension scores are included in the URL and may appear in browser, server, CDN, or analytics logs.

How often should I retake it?

The instrument keeps your previous reading and sets the two side by side when you retake — the Second Reading. There is no validated retest interval; repeat only if a raw answer-point comparison would be useful, and do not treat it as confirmed underlying change.

Why bands instead of percentiles?

Because this assessment does not collect a population score set, there is no reader population to rank you against — and we will not invent one. The 5-dimension profile groups selected answer points for editorial display; it is not a validated structural or decision-utility model.

Where does the evidence come from?

Every dimension insight cites peer-reviewed research, and most answer reveals do — 13 sources stand behind this instrument, each with DOI metadata supplied at build time; source relevance and claim interpretation remain editorial judgments. A few reveals are straightforward editorial reasoning from the same evidence base and carry no citation by design. The full list, with DOIs, is in the evidence file below.
