Developing a Sleepiness Scale for Nurses and Physicians: A Methodological Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimThe sleepiness of healthcare workers can negatively affect various aspects of healthcare, including patient and staff safety. Therefore, the aim of this study was to develop a valid and reliable scale to measure sleepiness in nurses and physicians working night shifts.
designA methodological study design was used in this study.
methodsThe scale items were developed through literature review and qualitative data analysis. The initial items of the instrument were developed based on the identified core concepts and presented to 21 experts for content validity assessment. In order to test the validity and reliability of the scale, a group of 255 nurses and 230 physicians working in a university hospital in a province of Turkey were included in the study between November 2023 and January 2024 by face-to-face survey method. Lawshe's content validity ratio, Kaiser-Mayer-Olkin coefficient, Bartlett's test, exploratory factor analysis, principal component analysis, Varimax factor rotation method, confirmatory factor analysis, Cronbach's alpha internal consistency coefficient, Spearman correlation coefficient and Wilcoxon Signed Ranks tests were used to analyse the data.
resultsThe sleepiness scale is a 19-item instrument with three factors: 'cognitive and physical effects of sleepiness on the process of working', 'difficulty keeping awake' and 'sleepiness coping strategies'. The Kaiser-Meyer-Olkin measures indicated that the data were sufficient for exploratory factor analysis. Bartlett's test indicated patterned relationships among the items (χ PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.
