Associations among perceptions of social support, negative affect, and quality of sleep in caregivers and noncaregivers.
The authors used structural equation modeling to examine associations among perceptions of negative affect, social support, and quality of sleep in a sample of caregivers (n = 175) and noncaregiver control participants (n = 169). The authors hypothesized that caregiver status would be related to sleep quality directly and also indirectly by way of negative affect and social support. This hypothesis was partially supported in that caregiving was found to be indirectly related to sleep quality. However, after accounting for the indirect effects of negative affect and social support, the direct effect of caregiving on sleep quality was no longer statistically significant. The structural model accounted for approximately 43% of the variance in sleep quality. The present findings may be useful in the development of successful sleep interventions for caregivers.
