This study employs slope-as-mediator techniques to explore how the daily association between ethnic/racial discrimination and sleep disturbances serves as an intermediary link between ethnic/racial identity (ERI) and psychological adjustment. In a diverse sample of 264 adolescents (M = 14.3 years old, 70% female, 76% United States born, 25% African American, 32% Asian American, 43% Latinx), discrimination was associated with sleep disturbance. Furthermore, ERI commitment buffered the impact of discrimination on sleep, whereas ERI exploration exacerbated the impact of discrimination. Finally, the daily level association between discrimination and sleep (i.e., daily slope) mediated the association between ERI and adolescent adjustment. Substantive links between discrimination and sleep are discussed as well as broader applications of slope-as-mediator techniques.
本研究采用斜率中介技术，探讨了种族/民族歧视与睡眠障碍之间的日常关联如何作为种族/民族认同（ERI）和心理适应之间的中介环节。在一个由 264 名青少年组成的多样化样本中（M=14.3 岁，70%为女性，76%为美国出生，25%为非裔美国人，32%为亚裔美国人，43%为拉丁裔），歧视与睡眠障碍有关。此外，ERI 承诺缓冲了歧视对睡眠的影响，而 ERI 探索则加剧了歧视的影响。最后，歧视与睡眠之间的日常水平关联（即每日斜率）中介了 ERI 与青少年适应之间的关联。讨论了歧视与睡眠之间的实质性联系，以及斜率中介技术的更广泛应用。
