Patient-Reported Outcome Measurement Information System (PROMIS) measures.
| Target domain | PROMIS battery | Details | Impairment definition |
|---|---|---|---|
| Sleep | Short Form v1.0 Sleep Disturbance 4a | Self-reported perceptions of sleep quality, sleep depth, restoration associated with sleep | T-score > 55 |
| Physical function | Short Form v2.0 Physical Function 10a | Self-reported capability to carry out instrumental activities of daily living | T-score < 45 |
| Depression/sadness | Short Form v1.0 Depression 4a | Affective and cognitive manifestation of depression | T-score > 55 |
| Anxiety/fear | Short Form v1.0 Anxiety 8a | Fear, anxious misery, hyperarousal, and related somatic symptoms | T-score > 55 |
Patient-Reported Outcomes Information System (PROMIS) short-form batteries were used to measure physical and mental health. The raw sum score of each battery was rescaled on the PROMIS score conversion table to determine standardized T-score where the mean of 50 represents the average level of the domain for US general adult population and every ten points represent one standard deviation (SD) from the mean. A threshold of 0.5 SD from the population mean was used to define the presence or absence of sleep disturbance (T-score >55), low physical function (T-score < 45), and symptoms of depression and anxiety (T-score >55).
