Abstract
Spending time with family ("family connection") is a salient aspect of adolescents' daily lives linked with healthy sleep. Less is known regarding the unique effects of parent and sibling connection on sleep. This study examined daily and average associations between parent/sibling connection and objective sleep (duration, efficiency) in a sample of Latinx adolescents (N = 195; M(age) = 18.11, SD = 0.41; 65.6% female) and explored familism values and family communication as moderators. Adolescents slept longer on days that they spent more time with siblings, and youth who typically spent more time with parents had longer sleep durations. Family communication and familism-obligation moderated associations between family connection and sleep. These results provide support for the role of family interactions in promoting healthy sleep among Latinx adolescents.
