Left-behind adolescents' biobehavioral adjustment, such as sleep, is poorly understood by research. Using daily data over one week from 90 middle school students (Mage = 13.69) in rural China, this study investigated daily bidirectional associations between negative peer interactions and sleep disturbances, and how these associations varied by parental migration. On days when adolescents reported higher levels of negative peer interactions, they also reported greater daytime dysfunction the following day. Conversely, when adolescents had more nighttime disturbances the previous night, they also reported higher levels of negative peer interactions. The effects of other sleep disturbance indicators (poor sleep quality the previous night and daytime dysfunction on the same day) on negative peer interactions were significant for adolescents with at least one parent migrating and for those with both parents migrating. Findings highlight the importance of considering dynamic interrelations between interpersonal and biobehavioral factors for the healthy development of left-behind adolescents.
