| 1. RELIABILITY | |
| A. Internal Consistency | Not Tested |
| Cronbach's (Describe) | |
| B. Reliability intraobserver or test-retest | Tested |
| Continuous scores: intraclass correlation coefficient (ICC) Dichotomus: Cohen kappa (Describe) |
The Kappa coefficient was > 0.90, 95% CI ranging from 0.84 to 0.98. A test-retest reliability study was conducted on patients with distal radius (n=64) or scaphoid (n=35) fractures. The total PRWE score’s test-retest reliability was excellent over both the short term (2-7 days, ICC > = 0.90) and the long term (1 year, ICC = 0.91). The pain subscale also had excellent short-term and long-term reliability (ICC = 0.90, 0.91, respectively). The function subscale demonstrated excellent short-term reliability (ICC > = 0.88) and moderate long-term disability (ICC = 0.61). |
