Perceived organizational support as a mediator between role clarity and work engagement among neurology specialist nurses: a cross-sectional study.
Article in BMC nursing, 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
backgroundSpecialist nursing has become an integral part of the healthcare system, with neurology specialist nurses playing vital roles in providing high-quality specialized care to patients with neurological disorders. Role clarity and work engagement (WE) are associated with various aspects of nursing practice and patient outcomes. Our aim was to investigate the levels of role clarity and WE among neurology specialist nurses in China and to explore how role clarity relates to WE.
methodsA cross-sectional study was conducted between April 2025 and July 2025 in China. Through convenience sampling, a total of 343 neurology specialist nurses from 11 provinces were initially invited, of whom 279 completed an online survey. The survey included a questionnaire assessing sociodemographic characteristics, as well as the role clarity scale, the Perceived Organizational Support Scale (POSS), and the Utrecht Work Engagement Scale (UWES). A mediation model was employed to test direct, indirect, and total effects using the bootstrap method. The mediating effect of perceived organizational support (POS) was analyzed using the SPSS process macro (Model 4).
resultsA total of 266 valid questionnaires were included in the analysis. Among neurology specialist nurses in China, role clarity and WE were at moderate and high levels, respectively. There were significantly positive correlations among role clarity, POS, and WE (p < 0.001). Furthermore, mediation analyses revealed that the positive relationship between role clarity and WE was mediated by POS (B = 0.758, 95% CI [0.510, 1.042]), whereas role clarity did not have a significant direct effect on WE (B = 0.061, 95% CI [-0.330, 0.424]).
conclusionPOS appeared to serve as a mediator in the positive relationship between role clarity and WE among neurology specialist nurses. Our findings highlight the value of clarifying the roles of these nurses and fostering a supportive climate to enhance perceived organizational support, strategies that are associated with improved work engagement. However, the observational nature of this study limits causal inferences, and further longitudinal studies are needed. CLINICAL TRIAL NUMBER: Not applicable.
