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

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.
