Abstract Accurate measurement of habitual sleep duration (HSD) is crucial for understanding the relationship between sleep and health. This study aimed to assess the bias and agreement limits between two commonly used short HSD self-report methods, considering sleep quality (SQ) and social jetlag (SJL) as potential predictors of bias. Data from 10,268 participants in the International COVID Sleep Study-II (ICOSS-II) were used. Method-Self and Method-MCTQ were compared. Method-Self involved a single question about average nightly sleep duration (HSD self ), while Method-MCTQ estimated HSD from reported sleep times on workdays (HSD MCTQwork ) and free days (HSD MCTQfree ). Sleep quality was evaluated using a Likert scale and the Insomnia Severity Index (ISI) to explore its influence on estimation bias. HSD self was on average 42.41 ± 67.42 min lower than HSD MCTQweek , with an agreement range within ± 133 min. The bias and agreement range between methods increased with poorer SQ. HSD MCTQwork showed less bias and better agreement with HSD self compared to HSD MCTQfree . Sleep duration irregularity was − 43.35 ± 78.26 min on average. Subjective sleep quality predicted a significant proportion of variance in HSD self and estimation bias. The two methods showed very poor agreement and a significant systematic bias, both worsening with poorer SQ. Method-MCTQ considered sleep intervals without adjusting for SQ issues such as wakefulness after sleep onset but accounted for sleep irre...
