Abstract
Objectives
In a sample of 90 American Indian (AI) college students (Age M(SD) = 21.47(3.02),
61.1% female), we investigated relationships between stress (perceived psychological
stress and recent negative life events), sense of belonging to the university community
and tribal community and sleep. We hypothesized that belonging and stress would associate
with sleep.
Methods
Participants wore a wrist accelerometer for 7 nights and answered surveys during an
in-lab visit.
Results
Sense of belonging to the university community associated with actigraphy-measured
wake after sleep onset (WASO) (β = −.45, t(80) = −3.98, P < .001, R2 change = 0.16), total sleep time (β = .30, t(80) = 2.49, P = .02, R2 change = .07), sleep efficiency (β = .38, t(80) = 3.29, P = .001, R2 change = .11) and subjective global sleep quality (β = −.44, t(75) = −4.82, P < .001, R2 change = .15). Sense of belonging to the tribal community predicted average wake
after sleep onset (β = −.29, t(80) = −2.64, P = .01, R2 change = 0.08). Total negative life events in the preceding year associated with
WASO (β = .24, t(80) = 2.19, P = .03, R2 change = 0.05), while perceived psychological stress associated with actigraphy-measured
sleep efficiency (β = −.28, t(80) = −2.25, P = .03, R2 change = 0.06) and subjective global sleep quality (β = .40, t(78) = 3.94, P < .001, R2 change = 0.16).
Conclusions
Stress and sense of belonging associate with sleep in AI college students. Future
research should investigate whether life stress and belonging may affect health in
this population by affecting patterns of sleep and investigate psychosocial resources
that may moderate the relationships between stress, belonging and sleep.
