Patient-reported outcome and physical function measures
| Measures | No. of items | Spanish translation | Reliability/validity tests in the literature |
|---|---|---|---|
| Self-Efficacy Exercise Regularly—Likert scale: 1 (not at all confident) to 10 (totally confident) | 3 | Y | (n = 478) mean 6.3 (SD 2.70). Internal consistency reliability 0.83. Test-retest reliability 0.86 |
| Health Promoting Lifestyle Profile (HPLP II)—Likert-type scales (1—never to 4—routinely). Subscales: spiritual growth, interpersonal relations, nutrition, physical activity, health responsibility, and stress management. | 52 | Y | Alpha reliability coefficient for the total scale is .922. Alpha coefficients for the subscales range from .702 to .904. |
| Self-Rated Health—“Would you say your health in general is excellent, very good, good, fair, or poor?” | 1 | Y | (n = 51) Mean 3.29 (SD 0.91). Test-retest reliability- 0.92 |
| PROMIS-29—8 domains include: anxiety, depression, fatigue, pain (interference and intensity), physical function, sleep disturbance, and satisfaction with social participation | 29 | Y | |
| Single Leg Stand (SLS)—determines if the patient can stand on one leg for 10 s. | N/A | Mean criterion-related validity was high (Pearson’s r = 0.84). Inter-observer reliability (ICC (2,1) = 0.81 (t1) and 0.82 (t2). Intra-observer reliability was on average ICC (2,1) = 0.88; Pearson’s r = 0.90 | |
| Functional Reach—measures the difference between a person’s arm length and maximal forward reach. | N/A | The Pearson correlation coefficient was .71 and the R2 using linear regression was .51; Test-retest reliability of the three postural control measures: intraclass correlation coefficient (ICC 1, 3) for center of pressure excursion (COPE) was .52, functional reach .81, and “yardstick” reach .92. | |
| Timed Up and Go Test (TUG)—measures the time to stand up, walk 3 m, turn, walk back to the chair, and sit down. | N/A | Inter-rater reliability- ICC ranged from 0.99–0.992. Intra-session, test-retest reliability, ICC (2, 1) was 0.978 | |
| Timed Up from the Floor Test | N/A | The interrater reliability between various pairs of testers (r = .99) | |
| The Disability of the Arm, Shoulder, and Hand (DASH)—measures generalized upper limb functional ability. | Y | DASH was found to correlate with other measures (r > 0.69) with a test-retest reliability of (ICC = 0.96) |
