Abstract
ABSTRACT Objectives Dysfunctional beliefs about sleep are associated with components of sleep health, but their association with global sleep health is understudied. Beliefs about sleep may systematically vary by race, which may influence the association between dysfunctional beliefs about sleep and global sleep health. This study aimed to investigate whether race influences the association between dysfunctional beliefs about sleep and global sleep health. Methods Data were collected as part of an online survey. Participants were Black (n = 181) and White (n = 179) adults who were matched on age, self-reported sex, and level of education. Global sleep health was measured using the RU-SATED and dysfunctional beliefs about sleep were measured using the DBAS-16. Moderation analyses were conducted to investigate whether race moderated the association between DBAS-16 total and subscale scores and RU-SATED total scores. Results Race moderated the associations between DBAS-16 total score and subscale scores and RU-SATED total score (b = 0.54, p < .001). Higher DBAS-16 scores were significantly associated with lower RU-SATED scores in the white sample, while this association was not significant in the Black sample, except for the Sleep Expectations subscale, where the association was not significant in the White sample, and it was significant in the Black sample. Conclusions These findings highlight that the association between dysfunctional beliefs about sleep and global sleep health may systematically vary by race which may have implications for promoting sleep health equity in racial minority populations through clinical and advocacy work. Future studies are needed to investigate what specific factors may be impacting these unique associations.
