This study examined the correspondence between self-reported and actigraph-measured nighttime sleep duration in adolescents, finding significant associations between the two methods that are applicable to adolescent community samples.
Objectives: This study provides the first investigation into the correspondence between self-reported and actigraph-measured nighttime sleep duration in adolescents that disambiguates between- versus withinperson associations. Moderators were evaluated to determine if between- and within-person correspondence vary by participant characteristics. Methods: One hundred fifty adolescents (14-21 years) reported sleep time for 1 week, while wearing an actigraph, and reported on moderators, including demographics (i.e., sex, age, ethnicity, and socioeconomic status), depressive symptoms, and perceived stress. Mixed effects models evaluated within- and betweenperson associations between self-reported and actigraph-measured sleep, and examined whether these associations differed by possible moderators. Results: Results indicated significant between- (b = 0.77, SE = 0.08, P <.001) and within-person (b = 0.51, SE = 0.04, P <.001) associations between self-reported and actigraph-measured sleep duration, with no significant moderation effects. Conclusions: Our results support the use of either self-reports or actigraphs to examine within-person nighttime sleep duration in adolescent community samples. (C) 2020 National Sleep Foundation.
