Table 8.

Correlations between self-report sleep measures and actigraphy

Actigraphy PROMIS
Sleep Disturbance		 PROMIS
Sleep-Related Impairment
Average TST (min) –.19 .05
Average SE (%) –.25 –.12
Average WASO (min) .21 .18
Average number of awakenings .17 .19

Note: PROMIS = Patient-Reported Outcomes Measurement Information System, TST = Total Sleep Time, SE = Sleep Efficiency, WASO = Wakening After Sleep Onset; Conducted Spearman correlations for the PROMIS Sleep-Related Impairment scale, actigraph wakening after sleep onset, and actigraph number of awakening because these variables were not normally distributed.
