Survey Doctor has retired PROMIS Adult Short Form v1.0 Sleep Disturbance 8a. All 33 raw-to-T-score conversions in its stored table differ from the reviewed official table. If you have an older Survey Doctor result, do not use its T-score, band, percentile, or trend as a verified PROMIS interpretation.
The old conversion fails.
The quick answer
The eight-item form asks about perceived nighttime sleep during the past seven days. A complete response produces a raw total from 8 to 40. That raw total must be converted with the official table for this exact form and scoring version.
The exact form matters.
Survey Doctor's retired conversion table does not match at any possible raw total. The product preserves an older number as history. It keeps that number outside current interpretation, comparison, trends, and primary score summaries.
The warning is absolute.
The form is no longer available for new collection or manual score entry.
What the form measured
The official Sleep Disturbance 8a form contains eight questions that people answer themselves. They describe the experience of sleep at night. Topics include sleep quality, refreshing sleep, difficulty falling asleep, restless sleep, worry, and satisfaction.
This is a report of perceived sleep. It does not measure breathing, movement, or sleep stages the way a sleep study can. It also cannot diagnose insomnia, sleep apnea, or the cause of poor sleep.
It is descriptive.
Why the old T-score is unverified
Every item contributes a value from 1 to 5. Two positively worded items are reversed in the stored scoring direction, so higher raw totals represent more sleep disturbance. All eight answers are required before table conversion.
The HealthMeasures sleep scoring manual maps a raw total of 8 to a T-score of 30.5 and a raw total of 40 to 77.5. Survey Doctor's retired table maps those same totals to 28.9 and 83.8. The other 31 entries also differ.
No entry matches.
Another official profile manual gives 77.6 at the upper endpoint rather than 77.5. That small conflict is another reason to keep the form and scoring version with a result. It does not make the retired Survey Doctor table valid.
Version details matter.
Can an old result be corrected?
Keep the original item answers if they are available. An authorized clinical or research team may be able to rescore an item-bearing record after confirming the exact form, completeness, and controlling table. Survey Doctor does not silently replace the historical score.
Rescoring needs evidence.
A score-only record is more limited. It does not establish the item answers or whether all eight were completed. It also cannot prove which scoring source was used. Do not reverse-engineer it into a new clinical result.
Keep the original.
Keep these details together:
- exact form name and version
- completion date
- individual item answers, when available
- raw total and converted score as originally recorded
- scoring method or table version
Sleep Disturbance is not daytime impairment
Sleep Disturbance describes the sleep experience itself. The retired PROMIS Sleep-Related Impairment 8a form describes alertness, concentration, and daily function while awake. One result cannot be converted into the other.
Read the older Sleep-Related Impairment 8a score guide for that separate history boundary.
Keep the measures apart.
When symptoms matter more than the number
Discuss persistent or worsening sleep problems with a healthcare provider. NHLBI guidance lists loud snoring, breathing that starts and stops, gasping, and daytime sleepiness among possible sleep apnea symptoms and advises discussing symptoms with a provider.
Do not rely on an old questionnaire score to judge whether driving is safe. NHTSA guidance explains the crash risk from drowsy driving and advises delaying driving until well rested.
The bottom line
The retired Sleep Disturbance 8a form measured perceived nighttime sleep over seven days. Its old Survey Doctor T-score is unverified because every stored conversion differs from the reviewed official table. Preserve the original record, but do not use its score or label for clinical comparison.
