(Hudson et al., 2008). We found improvement in both sleep efficiency
(2.3%-point increase) and sleep fragmentation (2.0%-point decrease).
Our evidence describing the effect of the intervention on selfreported
sleep disturbances and impairments was mixed. While selfreported
sleep disturbances decreased in the intervention compared
to the control group, self-reported sleep-related impairments increased
in the intervention group. This may be a function of the new
PROMIS measures. Previously, these scales were rigorously validated
in a large national study (Buysse, 2010), but they have not been fully
validated in a sample of HIV+ adults. This may have decreased the
sensitivity of these measures to detect changes in perceived sleep
quality. Future research should explore both questions in a larger
sample of HIV+ adults.
