OBJECTIVES Studies of discrimination and sleep have largely focused on between-person differences in discrimination as a correlate of sleep outcomes. A common criticism of this research is that standard questionnaire measures of discrimination may be confounded by personality and identity and are subject to recall bias. Partially addressing these limitations, the current study examined within-person, day-to-day fluctuations in perceived discrimination as a predictor of day-to-day fluctuations in sleep. The role of internalized racism as a moderator of the within-person association between discrimination and sleep was also considered. METHOD Participants were African American college students attending a predominantly White institution (N = 124, 26% male, Mage = 20.1, SD = 1.6). Each student was asked to complete a baseline questionnaire and a 9-day diary. Experiences of discrimination were assessed in the questionnaire and daily diary format. Sleep problems were measured each day using self-report measures focusing on sleep quality. Internalized racism was assessed with the miseducation scale, which captures the degree to which individuals associate negative characteristics such as laziness and criminality with their racial/ethnic group. Established measures of racial identity were considered as covariates. RESULTS Multilevel analyses indicated that on days when participants experienced more discrimination, subsequent sleep problems increased (B = .037, SE = .017, p = .034). Furthermore, this within-person association was moderated by internalized racism such that the effects of daily discrimination on sleep were stronger among those who scored higher on miseducation (B = .046, SE = .021, p = .033). CONCLUSIONS Overall, results suggest that ongoing efforts to reduce discrimination, support the adjustment of racial/ethnic minority students, and address internalized racism are warranted.

歧视经历的日常波动：与睡眠的关联以及非裔美国大学生内部种族主义的调节作用。

目的对歧视和睡眠的研究主要集中在人与人之间的歧视差异上，这些差异是与睡眠结果相关的。对这项研究的普遍批评是，标准的问卷调查中的歧视性测量可能会因人格和身份而混淆，并容易引起回忆偏见。本研究部分解决了这些局限性，研究了人与人之间日常差异的感知歧视，以此作为睡眠中每日波动的预测指标。还考虑到内部种族主义作为人与人之间歧视和睡眠之间联系的调节者的作用。方法参加者为就读白人学校的非裔美国大学生（N = 124，男26％，法师= 20.1，SD = 1.6）。每位学生被要求填写一份基线调查表和9天的日记。歧视的经历以问卷和每日日记的形式进行评估。每天使用针对睡眠质量的自我报告措施来衡量睡眠问题。内部化的种族主义用教育程度表进行了评估，该表反映了个人将懒惰和犯罪等消极特征与种族/族裔群体联系起来的程度。已建立的种族认同测度被视为协变量。结果多级分析表明，在参与者受到更多歧视的日子里，随后的睡眠问题增加（B = .037，SE = .017，p = .034）。此外，这种人际交往受到内部种族主义的控制，以致在受教育程度较高的人中，日常歧视对睡眠的影响更强（B = .046，SE = .021，p = .033）。结论总体而言，研究结果表明，为减少歧视，支持调整种族/族裔少数族裔学生以及解决内部种族主义，我们需要做出持续的努力。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
