Abstract
Objective
To investigate self-report measures of sleep disturbances and sleep-related impairments
in samples of individuals with multiple sclerosis (MS) or spinal cord injury (SCI).
Design
Cross-sectional survey.
Setting
Community based.
Participants
Adults (age ≥18y) (N=700) with either MS (n=461) or SCI (n=239) who were enrolled
in a longitudinal survey of self-reported health outcomes and who completed self-report
sleep measures at 1 time point.
Interventions
None.
Main Outcome Measures
Medical Outcomes Study Sleep Scale (MOS-S), Patient Reported Outcomes Measurement
Information System (PROMIS) sleep disturbance short form, and PROMIS sleep-related
impairments short form.
Results
Mean scores on the MOS-S sleep index II were significantly worse for both the MS and
SCI samples than those of previously reported samples representative of the U.S. general
population (P<.0001 for each group). The PROMIS sleep disturbance short form and PROMIS sleep-related
impairments short form scores of the MS sample were also significantly different from
those reported for the calibration cohort (P<.0001 on each scale). However, although the scores of the SCI sample were significantly
different from those of the comparison cohort for the PROMIS sleep-related impairments
short form (P=.045), the differences on the PROMIS sleep disturbance short form were not significant
(P=.069).
Conclusions
Although the MOS-S scores for the MS and SCI cohorts clearly indicated significantly
high levels of sleep-related problems and were consistent with existing literature,
the more ambiguous findings from the PROMIS sleep disturbance short form and PROMIS
sleep-related impairments short form suggest that not enough is currently known about
how these instruments function when applied to those with chronic neurologic dysfunction.
