Randomized trial examines accuracy of self-reported sleep metrics in different age and sex groups, suggesting no significant bias found.

This research investigates whether age or sex influences the accuracy of self-reported sleep assessments among healthy individuals.
Analyzed data from 90 younger and 24 older participants over baseline and forced desynchrony conditions.
Compared self-reported sleep measures to polysomnography (PSG) recordings using linear mixed-effects models.
Assessed variables included sleep latency, number of awakenings, total sleep time, and habitual versus chronic sleep restriction.
Participants consistently overestimated sleep latency and underestimated number of awakenings during baseline and forced desynchrony.
No significant differences in self-assessment accuracy were found between men and women.
Older participants had smaller differences in perceived latency for short sleeps but larger discrepancies for longer sleep latencies.

Wang et al. (2026) studied this question.
