Objective:

To examine the associations between sleep quality, social support, psychological resilience, smartphone addiction, and negative emotions among medical students, aiming to provide a basis for targeted intervention measures.

Approach:

Key Findings:

• Social support and psychological resilience were negatively correlated with poor sleep quality (p < 0.01).
• Smartphone addiction and negative emotions were positively correlated with poor sleep quality (p < 0.01).
• Social support has a direct positive effect on sleep quality and an indirect effect via smartphone addiction and negative emotion.
• Psychological resilience does not directly impact sleep quality but has an indirect effect through smartphone addiction and negative emotion.

Interpretation:

The study clarifies the pathways through which social support and psychological resilience influence sleep quality, highlighting the mediating roles of smartphone addiction and negative emotions, with implications for future research and interventions.

Limitations:

• The study is cross-sectional, limiting causal inferences.
• Self-report measures may introduce bias.
• The focus on medical students may limit the generalizability of the findings.

Conclusion:

Findings provide insights for formulating interventions to improve sleep health among medical students.
