Latent profile analysis of sleep quality and its association with psychological resilience among emergency department nurses.

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
Objective: Emergency department nurses are consistently exposed to high-intensity and high-pressure working conditions, leading to poor sleep quality. Psychological resilience can help alleviate the negative impacts of work stress. However, few studies have explored how resilience varies across distinct subgroups defined by different sleep profiles. This study employed latent profile analysis to identify distinct sleep-quality profiles among emergency department nurses and explored their association with psychological resilience to provide a basis for targeted interventions. Methods: From October to December 2025, 611 emergency nurses were recruited from 12 tertiary hospitals in Shandong through convenience sampling. Data were collected using a sociodemographic questionnaire, the Connor-Davidson Resilience Scale, and the Pittsburgh Sleep Quality Index. Sleep quality profiles were determined through latent profile analysis, and associated factors were analyzed using multiple logistic regression. Results: Emergency department nurses exhibited generally poor sleep quality, which was classified into four distinct profiles: "severely disturbed sleep" (8.0%), "sleep onset difficulty-sleep medication use" (15.1%), "mildly disturbed sleep" (26.7%), and "good sleep quality" (50.2%). Psychological resilience, age, work experience, monthly income, and monthly night shift number were significantly associated with these sleep quality profiles ( Conclusion: Emergency department nurses exhibit distinct sleep quality profiles. Targeted interventions addressing the specific factors associated with each subgroup could improve their sleep outcomes.
