This study provides the first investigation into the correspondence between self-reported and actigraph-measured nighttime sleep duration in adolescents that disambiguates between- versus within-person associations. Moderators were evaluated to determine if between- and within-person correspondence vary by participant characteristics.
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 between-person associations between self-reported and actigraph-measured sleep, and examined whether these associations differed by possible moderators.
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.
Our results support the use of either self-reports or actigraphs to examine within-person nighttime sleep duration in adolescent community samples.
本研究首次调查了青少年自我报告和活动记录仪测量的夜间睡眠时间之间的一致性，区分了个体内和个体间的关联。评估了调节因素，以确定个体内和个体间的一致性是否因参与者的特征而异。
150 名青少年（14-21 岁）报告了一周的睡眠时间，同时佩戴活动记录仪，并报告了调节因素，包括人口统计学特征（即性别、年龄、种族和社会经济地位）、抑郁症状和感知压力。混合效应模型评估了自我报告和活动记录仪测量的睡眠之间的个体内和个体间关联，并检查了这些关联是否因可能的调节因素而不同。
结果表明，自我报告和活动记录仪测量的睡眠持续时间之间存在显著的个体间（b=0.77，SE=0.08，P<.001）和个体内（b=0.51，SE=0.04，P<.001）关联，没有显著的调节效应。
我们的结果支持在青少年社区样本中使用自我报告或活动记录仪来检查个体内夜间睡眠时间。
