Previous research has indicated that school engagement tends to decline across high school. At the same time, sleep problems and exposure to social stressors such as ethnic/racial discrimination increase. The current study uses a biopsychosocial perspective to examine the interactive and prospective effects of sleep and discrimination on trajectories of academic performance.
Growth curve models were used to explore changes in 6 waves of academic outcomes in a sample of 310 ethnically and racially diverse adolescents (mean age = 14.47 years, SD = .78, and 64.1% female). Ethnic/racial discrimination was assessed at Time 1 in a single survey. Sleep quality and duration were also assessed at Time 1 with daily diary surveys. School engagement and grades were reported every 6 months for 3 years.
Higher self-reported sleep quality in the ninth grade was associated with higher levels of academic engagement at the start of high school. Ethnic/racial discrimination moderated the relationship between sleep quality and engagement such that adolescents reporting low levels of discrimination reported a steeper increase in engagement over time, whereas their peers reporting poor sleep quality and high levels of discrimination reported the worse engagement in the ninth grade and throughout high school.
The combination of poor sleep quality and high levels of discrimination in ninth grade has downstream consequences for adolescent academic outcomes. This study applies the biopsychosocial model to understand the development and daily experiences of diverse adolescents. (PsycINFO Database Record
以往的研究表明，高中生的学校参与度往往会随着年级的升高而下降。与此同时，睡眠问题以及遭受种族/种族歧视等社会压力源的情况却有所增加。本研究采用生物心理社会视角，考察了睡眠和歧视对学业成绩轨迹的交互和前瞻性影响。
使用增长曲线模型来探讨在一个由 310 名种族和民族多样化的青少年组成的样本中（平均年龄= 14.47 岁，标准差= 0.78，64.1%为女性），6 波学业成绩的变化情况。在一次调查中评估了种族/种族歧视的时间 1。睡眠质量和时长也在时间 1 通过每日日记调查进行评估。学校参与度和成绩每 6 个月报告一次，为期 3 年。
在九年级时自我报告的睡眠质量较高，与高中一开始的学业参与度较高有关。种族/种族歧视调节了睡眠质量与参与度之间的关系，即报告歧视程度较低的青少年随着时间的推移，参与度的增加幅度更大，而那些报告睡眠质量差、歧视程度高的同龄人在九年级和整个高中期间的参与度都较差。
在九年级时，睡眠质量差和歧视程度高的情况相结合，对青少年的学业成绩有后续影响。本研究应用生物心理社会模型来理解不同青少年的发展和日常经历。
