Abstract
Forty-six percent of nurses in a rotating shift system had an intermediate chronotype, while 53.7% had an evening chronotype.
- Evening chronotypes reported significantly poorer subjective sleep quality compared to intermediate chronotypes.
- Nurses with an evening chronotype experienced shorter total sleep duration and longer sleep onset latency.
- Lower sleep efficiency was observed in evening chronotypes relative to their intermediate counterparts.
- Performance on composite and visual memory tests was worse among evening chronotypes.
- No significant differences in near-miss incidents were found between the chronotype groups.
