The association between resilience and fatigue among mariners during ocean voyages: a chain mediating effect of coping style and psychological stress.
Article in BMC public health, 2025. 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
backgroundFatigue seriously reduces the sensory sensitivity and operational efficiency ofmariners, which is a major safety threat to ship navigation. This study aimed to investigate the relationship between resilience and fatigue and to explore the chain-mediated role of coping style and psychological stress among mariners during ocean voyages.
methodsUsing Connor-Davidson resilience scale, simplified coping style questionnaire, psychological stress self-evaluation test and multidimensional fatigue inventory, a questionnaire survey was conducted on 510 mariners from a Shandong fleet who finished a 32-day ocean voyage on September 12, 2023. SPSS 26.0 was employed to perform correlation analysis, while Amos 21.0 was applied to establish structural equation model and demonstrate the mediator effects.
resultsDaily working hours, negative coping style and psychological stress were positively correlated with fatigue, while resilience was negatively related to fatigue (all P < 0.01). The structural equation indicated that the 4 paths of "resilience → fatigue", "resilience → psychological stress → fatigue", "resilience → positive coping → psychological stress → fatigue" and "resilience → negative coping → psychological stress → fatigue" occupied 68.72%, 11.45%, 9.99% and 9.84% of the total effect, respectively (all P < 0.05), suggesting the validity of hypothesis.
conclusionResilience exerts significant direct and indirect effects on fatigue of mariners during ocean voyages. In addition, coping style and psychological stress partially and serially mediate the relation between resilience and fatigue. The results have significant implications for the intervention and prevention of fatigue, providing additional evidence for the relationship between resilience and fatigue among mariners during ocean voyages.
