Hypothesis
More negative affect before sleep would predict worse sleep health, whereas more positive affect before sleep would predict better sleep health.
Conclusion
Negative affect was most consistently associated with sleep health at the individual level.
Supporting Evidence
- Approximately 40% of participants had poor sleep quality.
- Higher within-person negative affect predicted shorter sleep duration.
- Higher between-person negative affect predicted shorter sleep duration.
- Higher within-person positive affect predicted longer sleep onset latency.
- Higher within- and between-person positive affect predicted more feeling rested.
Takeaway
If students feel bad before bed, they might not sleep well. But if they feel good, they might sleep better.
Methodology
A correlational design with 54 health science students completing baseline and 7-day ambulatory assessments.
Potential Biases
Gender imbalance with most participants being female may affect generalizability.
Limitations
The study was correlational, and causal inference cannot be made; also, the sample was predominantly female.
Participant Demographics
Mean age 19.8 years, 92.6% female, from a large medical university in Shanghai, China.
