PROMIS Sleep-Related Impairment 8a (retired)

Overview

PROMIS Adult Short Form v1.0 Sleep-Related Impairment 8a asks about daytime effects linked to poor sleep during the past seven days. Survey Doctor retired it because every raw-to-T-score mapping conflicts with the revised official table. Historical numbers remain stored, but they are quarantined from interpretation, comparison, trends, and primary exports.

The form is unavailable to take.

What this questionnaire covers

The official respondent form has eight self-report items. They cover the daytime effects people connect with poor sleep, including:

• Tiredness and sleepiness
• Alertness after waking
• Difficulty concentrating
• Trouble completing daily tasks
• Irritability linked to poor sleep
• Difficulty staying awake

The form focuses on daytime function. It does not ask for a detailed account of sleep quality, sleep duration, or nighttime awakenings.

Daytime effects are the focus.

Why this page has no score table

Each completed item contributes a value from 1 to 5. One positively worded item has reversed stored values, so higher raw totals consistently represent more sleep-related impairment.

All eight items must be answered. Their values add to a raw total from 8 to 40, which is converted with the table for this exact form and scoring version.

The current HealthMeasures sleep scoring manual maps a complete raw total of 8 to a T-score of 30.0 and 40 to 80.1. It also says the 8a table was revised in 2014 and earlier scores should be rescored with that table.

The retired digital table maps those same endpoint totals to 28.9 and 81.4. All 33 mappings differ from the revised official table.

Every mapping changes.

Survey Doctor treats the historical T-score and its label as unverified instead of silently replacing them. Do not treat a current or historical Survey Doctor T-score as a verified PROMIS result.

This page does not publish universal severity bands or percentiles. Interpretation depends on the selected reference and clinical purpose.

No score from this form confirms a sleep disorder or explains why someone feels tired. Diagnosis requires a broader clinical assessment.

If you received a result here before retirement

Keep the form name, completion date, scoring version, and original item responses if you have them. Compare the result with another PROMIS score only when the same form and scoring method were used.

If the version is missing, the responsible clinician or study team should decide whether the record is suitable for comparison. A score-only record may not support a later rescore.

When all item answers remain available, a later verified correction may support rescoring after a formal history decision. A score-only record cannot be corrected from the T-score alone.

How it differs from Sleep Disturbance

The two PROMIS sleep forms are companions, but they are not interchangeable:

Someone may sleep poorly without reporting the same degree of daytime limitation. Another person may feel very sleepy during the day without recognizing a nighttime problem. Neither questionnaire identifies the cause.

When to seek help without relying on a score

Talk with a healthcare provider when tiredness, concentration problems, or sleepiness persist or interfere with daily life. Describe what happens, when it happens, and whether it affects work, school, or relationships.

Do not drive or use dangerous equipment when you are struggling to stay awake. Seek prompt medical advice for severe or unexplained daytime sleepiness.
