- Allocation: RandomizedIntervention Model: Factorial AssignmentIntervention Model Description: All participants will complete two nights in the sleep laboratory. One night will be a non-rejection control night. The other night will be a rejection task night. In this regard, African American and Caucasian American participants will be randomized to one of two conditions. All participants will be exposed to social rejection prior to bedtime; however, they will either be rejected by a person of their own race (in-group member) or a different race (out-group member)Masking: Double (Participant, Outcomes Assessor)Masking Description: Participants will be blind to condition until the debriefing, which occurs the morning following the social-rejection task.Primary Purpose: Basic Science
Participation Requirements
- Age
- Between 18 years and 62 years

African Americans (AA) are disproportionally burdened by cardiovascular disease compared to Caucasian Americans (CA). Poor sleep, which is more common among AA, may serve as an important pathway in understanding these disparities. Race-based rejection has been cross-sectionally related to poor sleep and negative cardiovascular outcomes. To test the links between social experiences and sleep, participants will spend two nights in the sleep laboratory. One night will be a control night where participants complete low arousal tasks prior to bedtime. On a second night, the investigators will randomize 80 AA and 80 CA to either race-based social rejection (i.e., being rejected by an out-group member) or same-race social rejection prior to bedtime to test the causal influences of race-based rejection on objective sleep parameters, measured using polysomnography, and nocturnal cardiovascular functioning. The investigators will test group differences on these outcomes as well as within subjects by testing impact of rejection compared to a non-rejection control night in the sleep laboratory. The order of the control and rejection task night will be counterbalanced.
