Discrepancy between self-reported and objective sleep duration among dementia caregivers and noncaregivers

Topic: Health services, long-term care and technology
Caregivers showed a greater discrepancy in sleep duration than did noncaregivers (-0.46 hour vs 0.22 hour, respectively; P = .003). In a regression model, however, caregiving status was no longer associated with this sleep duration discrepancy, when covariates were accounted for. Higher positive affect was significantly associated with less sleep duration discrepancy (R2 = 11.3%, P = .014). The Sobel test of mediation showed that 26% of the effect of caregiving on this sleep discrepancy was attributable to caregivers with low positive affect. The findings suggest a potential mediating role of positive affect on the relationship between caregiving status and sleep duration discrepancy. As an aid for understanding the role of lower positive affect, use of actigraphy may help address sleep discrepancy in caregivers. CITATION: Song Y, Moore RC, Jeste DV, et al.

Key findings
- Caregivers showed a greater discrepancy in sleep duration than did noncaregivers (-0.46 hour vs 0.22 hour, respectively; P = .003).
- In a regression model, however, caregiving status was no longer associated with this sleep duration discrepancy, when covariates were accounted for.
- Higher positive affect was significantly associated with less sleep duration discrepancy (R2 = 11.3%, P = .014).
- The Sobel test of mediation showed that 26% of the effect of caregiving on this sleep discrepancy was attributable to caregivers with low positive affect.
- The findings suggest a potential mediating role of positive affect on the relationship between caregiving status and sleep duration discrepancy.

How this study scored 61/100
Published in a peer-reviewed journal, and it is a snapshot of people at one point in time. Scored zero for randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 34 of the 56 points we could judge it on, which is 61 out of 100.
