Impact of Perceived Stress on Work Engagement Among Intensive Care Unit Nurses: The Mediating Effects of Dispositional Mindfulness and Sleep Quality.
Article in Nursing open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimTo investigate the mediating effects of mindfulness and sleep quality on the relationship between perceived stress and work engagement among intensive care unit (ICU) nurses in China.
designA cross-sectional survey was conducted with 623 ICU nurses from tertiary hospitals in China.
methodsData were collected using validated questionnaires, including the Perceived Stress Scale, Utrecht Work Engagement Scale-9, Five Facet Mindfulness Questionnaire, and Pittsburgh Sleep Quality Index. Correlation analysis and structural equation modelling were used to examine the mediating effects of mindfulness and sleep quality. Furthermore, partial correlations were conducted to control for confounders such as night shifts, and an a posteriori power analysis was performed.
resultsPerceived stress was negatively correlated with work engagement (r = -0.559, p < 0.001) and dispositional mindfulness (r = -0.686, p < 0.001) and positively correlated with poor sleep quality (r = 0.475, p < 0.001). Structural equation modelling showed that perceived stress had a direct negative effect on work engagement (beta [β] = -0.432, p < 0.001) and an indirect effect mediated by mindfulness (β = -0.083, p < 0.001) and sleep quality (β = -0.043, p < 0.001). The combined mediating effects accounted for 22.44% of the total effect. The parallel mediation model showed superior fit compared to serial mediation and alternative models (AIC = 145.2 vs. 162.8; delta-chi-square = 18.6, p < 0.01).
conclusionDispositional mindfulness and sleep quality were significantly associated with the relationship between perceived stress and work engagement among ICU nurses. These findings suggest that strategies aimed at improving dispositional mindfulness through training and sleep quality warrant investigation as potential means to mitigate perceived stress and enhance work engagement in this population. PATIENT OR PUBLIC CONTRIBUTION: These findings provide actionable insights for nursing managers to develop interventions promoting mental well-being and productivity in ICU settings.
