PMID 42093095WHAT IT FOUND
A 23-item scale for nurses assessing adults with sleep disturbance grouped patient reports into personal and daily-life impacts and appeared consistent, but it has not been tested to guide care or improve outcomes.
Key findings
01The final scale had 23 items and two sub-dimensions.
02The scale's two parts were confirmed in a separate sample, and responses were consistent across items.
03The scale has no cut-off score, and test-retest stability was not assessed.

What it does not show
The sample came from a single hospital clinic in Turkey and was mainly adults aged 18 to 35 and single, so it may not apply to older adults, other marital statuses, or other settings. Only people with a Pittsburgh Sleep Quality Index score of 5 or higher and reported low quality of life were included, so it says little about milder sleep problems or higher quality of life. Test-retest stability was not assessed, so it is unknown whether scores remain stable over time. The scale has no cut-off score, so it cannot classify a patient as having a defined level of sleep-disturbance impact. The Pittsburgh Sleep Quality Index had modest internal consistency in this study (0.69 and 0.68), which may affect how well participants were classified as having sleep disturbance.

The easy way to misread this
Do not read this as evidence that the scale improves care or patient outcomes. It was a validation study in Turkish adults with sleep disturbance, has no cut-off score, and did not test stability over time.
