| Limitations | >=5 European languages (English) |
| Observations | |
| 1. RELIABILITY | |
| A. Internal Consistency | Tested |
| Cronbach's (Describe) |
In the French translation, a Cronbach’s alpha of 0.65 was found revealing moderate internal consistency. When one item was removed from the analysis, the lowest Cronbach’s alpha obtained was 0.55 |
| B. Reliability intraobserver or test-retest | Not Tested |
| Continuous scores: intraclass correlation coefficient (ICC) Dichotomus: Cohen kappa (Describe) |
|
| C. Reliability interobserver or Measurement error | Not Tested |
| Standard error of measurement (SEM), smallest detectable change (SDC) or Limits of agreement (LoA) (Describe) |
|
| 2. VALIDITY | |
| A. Content validity: face validity | Tested |
| Expert opinion (relevance and comprehensiveness) (Describe) |
|
| B. Construct Validity: Structural validity |
Tested |
| Hypotheses-testing | Tested |
| Cross-cultural validity | Not Tested |
| Brief Description |
Cross-sectional construct validity was demonstrated through the ‘moderate’ kappa for agreement between stratification by the Keele STarT MSK Tool and the ÖMSPQ: 0.49 and 0.48 ‘moderate’ for the two possible Keele STarT MSK Tool cut-offs, with overall agreement 76% and 73% |
| C. Criterion validity | Not Tested |
| Comparison with a 'gold standard' Continuous scores: correlations, ROC curves Dichotomus: Sensitivity & Specificity (Describe) |
