Measurement bias in adolescent sleep duration: Comparison of self-reported and actigraphy-assessed sleep duration among adolescents in the Future of Families and Child-Wellbeing Study.
Article in Sleep health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo assess differences and potential measurement bias in adolescent sleep duration, we compared self-report and actigraphy-assessed sleep duration in the Future of Families and Child Wellbeing Study (age 15 wave).
methodsParticipants (N = 634; mean age 15.4 years; 51% Black, 30% Hispanic, and 18% White) self-reported typical weekday and weekend bedtimes and waketimes before wearing a wrist actigraph for 1 week. Linear regression models estimated concordance between self-reported and actigraphy-assessed sleep duration overall and stratified by race, ethnicity, and socioeconomic status (primary caregiver education and household income-to-poverty threshold ratio). Agreement of sleep duration categories [short (<8 hours), recommended (8-10 hours), and long (>10 hours)] was estimated using Kappa statistics.
resultsSelf-reported sleep duration overestimated actigraphy-assessed duration by 27.87 minutes (95% CI: 34.96, 20.78) after adjustment. Agreement between duration categories was 73% (ƙw = 0.12, 95% CI: 0.07, 0.18). The mean difference was larger on weekends (74.3 ± 144.7 minutes) than weekdays (27.5 ± 92.7 minutes). Within-group analyses showed self-reported duration overestimated actigraphy-assessed duration for Black adolescents and those with lower socioeconomic status (i.e., primary caregivers with a high school education or less).
conclusionsReliance on self-report may misclassify sleep duration and underestimate insufficient sleep, particularly in marginalized groups, underscoring the need to understand measurement bias when objective measures are unavailable.
