| Limitations | |
| Observations |
The SANE scale displayed evidence of reliability and validity and responsive tool in patients with shoulder related pathologies |
| 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 ICC was ≥0.80. When assessed amongst patients with shoulder disorders, the SANE reports good reliability (ICC = 0.76, SE 3.4) and agreement across a variety of treatment groups (rotator cuff repair, ICC = 0.85, SE 3.4; total shoulder arthroplasty, ICC = 0.72, SE 5.2; physiotherapy, ICC = 0.82, SE 2.9) |
| C. Reliability interobserver or Measurement error | Tested |
| Standard error of measurement (SEM), smallest detectable change (SDC) or Limits of agreement (LoA) (Describe) |
SEM ranged from 4.23 – 7.82 points. MDC ranged from 7.0% – 8.0% |
| 2. VALIDITY | |
| A. Content validity: face validity | Tested |
| Expert opinion (relevance and comprehensiveness) (Describe) |
Evidence from three very good to excellent quality studies indicated that the SANE scale’s validity parameters ranged from moderate to very strong (Pearson coefficient ≥ 0.50) |
| B. Construct Validity: Structural validity |
Not Tested |
| Hypotheses-testing | Tested |
| Cross-cultural validity | Not Tested |
| Brief Description | |
| C. Criterion validity | Not Tested |
| Comparison with a 'gold standard' Continuous scores: correlations, ROC curves Dichotomus: Sensitivity & Specificity (Describe) |
