Latent profiles of professional identity and sleep quality and associations with anxiety symptoms among emergency nurses.
Article in Frontiers in public health, 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
Background: Emergency nurses are exposed to sustained occupational stress and are at high risk for anxiety symptoms. Professional identity and sleep quality are both closely related to mental health; however, most existing studies have adopted variable-centered approaches that may obscure meaningful heterogeneity within this population. Methods: A cross-sectional survey was conducted among registered emergency nurses at a tertiary teaching hospital in China between March and June 2024. Participants completed questionnaires assessing professional identity (Professional Identity Scale for Nurses), sleep quality (Pittsburgh Sleep Quality Index), and anxiety symptoms (Generalized Anxiety Disorder-7). Latent profile analysis was performed using the total professional identity score and seven sleep quality component scores as continuous indicators. Differences in anxiety symptoms and demographic characteristics across profiles were examined using chi-square tests and one-way ANOVA. Results: Three latent profiles were identified: an Adaptive and Well-Functioning profile, a Sleep-Disturbed with Moderate Identity profile, and an At-Risk with Low Identity and Poor Sleep profile. These profiles showed significantly different prevalences of anxiety symptoms, whereas no significant differences were observed in demographic or occupational characteristics across profiles. Conclusions: Emergency nurses exhibit distinct and clinically meaningful patterns of professional identity and sleep quality that are differentially associated with anxiety symptoms. The identification of a prominent Sleep-Disturbed profile as an important factor associated with higher levels of anxiety symptoms, even among nurses with relatively preserved professional identity. By explicitly capturing heterogeneity that would not be apparent using variable-centered approaches alone, a person-centered perspective may provide insights for the development of more tailored mental health support strategies for emergency nursing populations.
