This 10-day study aimed to (1) assess the effectiveness of a text message-based sleep intervention and (2) determine whether the intervention was equally effective for non-Hispanic whites and racial-ethnic minority adolescents.
Participants were 46 (50% female) adolescents (13-18 years; mean=15.75 years old, SD=0.98) from a public high school in the Midwest.
Participants were randomly assigned to a control or text message intervention condition. Only participants in the intervention condition received 2 text messages outlining individualized bedtime goals daily, for 8 weekdays.
All participants attended a sleep lecture, wore a sleep monitor, and completed baseline and exit surveys that assessed demographics, subjective sleep, lifestyle, and psychosocial adjustment variables.
Results of a 2 (intervention, control) × 2 (pre-intervention, postintervention) analysis of variance test revealed no significant intervention × time interaction effect (F=0.020, P=.889) in the full sample. This effect, however, was significantly moderated by race-ethnicity: Results indicated a significant intervention × time × race interaction (F=8.050, P=.007, partial η=.183) such that the intervention significantly improved sleep hours (by approximately 1 hour) only among non-Hispanic whites (and not among adolescents of racial-ethnic minority status).
Adolescents from racial-ethnic minority groups may face significant barriers that interfere with their ability to successfully alter their sleep-wake patterns and maximize sleep hours.
这项为期 10 天的研究旨在：(1)评估基于短信的睡眠干预的有效性；(2)确定该干预措施对非西班牙裔白人和种族少数民族青少年是否同样有效。
参与者为来自中西部一所公立高中的 46 名(50%为女性)青少年(13-18 岁；平均年龄=15.75 岁，标准差=0.98)。
参与者被随机分配到对照组或短信干预组。只有干预组的参与者每天会收到 2 条概述个性化就寝目标的短信，持续 8 个工作日。
所有参与者都参加了睡眠讲座，佩戴了睡眠监测器，并完成了基线和退出调查，这些调查评估了人口统计学、主观睡眠、生活方式和心理社会调整变量。
2(干预、对照)×2(干预前、干预后)方差分析检验的结果显示，在全样本中，干预×时间的交互作用效应不显著(F=0.020，P=.889)。然而，这种效应被种族-民族显著调节：结果表明，干预×时间×种族的交互作用显著(F=8.050，P=.007，部分η=.183)，即干预仅显著改善了非西班牙裔白人群体的睡眠时间(约 1 小时)，而对种族少数民族群体的青少年没有影响。
来自种族少数民族群体的青少年可能面临重大障碍，这些障碍干扰了他们成功改变睡眠-觉醒模式和最大限度地增加睡眠时间的能力。
