Given the documented benefits of later school start times on adolescents' mental health, the aim of the current study was to examine if the association between school start times and depressive symptoms differed across adolescents from families of different socioeconomic status levels.
Using a cross-sectional design, the current study incorporated an online survey for high school students and their parents across the United States, with average sleep duration measured through a 7-day sleep diary. A total of 193 adolescent (Mean = 15.7 years old, SD = .94; 54.4% female; 71% white) and parent (Mean = 47.6 years old, SD = 5.4; 80% female; 79% white) dyads participated. Adolescents reported on depressive symptoms, sleep quality and duration, chronotype, and demographic covariates; parents reported on school start times and socioeconomic status.
Results suggested that only in adolescents from higher socioeconomic status families (+1 SD) did the association between later start times and fewer depressive symptoms emerge as significant.
Although more school start times research is needed to understand its impact across diverse groups of students, current findings suggest a disproportionate benefit of reduced depression for youth from families of higher socioeconomic status with having a later start time.
鉴于学校推迟上课时间对青少年心理健康的益处已得到充分证实，本研究旨在探讨学校上课时间与抑郁症状之间的关联是否因家庭社会经济地位水平不同而存在差异。
本研究采用横断面设计，对美国各地的高中生及其家长进行了在线调查，通过 7 天睡眠日记来测量平均睡眠时间。共有 193 名青少年（平均年龄为 15.7 岁，标准差为.94；女性占 54.4%；71%为白人）和家长（平均年龄为 47.6 岁，标准差为 5.4；女性占 80%；79%为白人）参与了研究。青少年报告了抑郁症状、睡眠质量和时长、昼夜节律和人口统计学协变量；家长报告了学校上课时间和社会经济地位。
结果表明，只有在来自较高社会经济地位家庭的青少年中（+1 个标准差），上学时间较晚与较少抑郁症状之间的关联才变得显著。
尽管需要更多的学校上课时间研究来了解其对不同群体学生的影响，但目前的研究结果表明，对于来自较高社会经济地位家庭的青少年来说，推迟上学时间对减少抑郁的影响更大。
