Property | Rating | Quality Criteria |
---|---|---|
Reliability | Â | Â |
Internal consistency | + | (Sub)scale unidimensional AND Cronbach's alpha(s) ≥ 0.70 |
 | ? | Dimensionality not known OR Cronbach's alpha not determined |
 | - | (Sub)scale not unidimensional OR Cronbach's alpha(s) < 0.70 |
Measurement error | + | MIC > SDC OR MIC outside the LOA |
 | ? | MIC not defined |
 | - | MIC ≤ SDC OR MIC equals or inside LOA |
Reliability | + | ICC/weighted Kappa ≥ 0.70 OR Pearson's r ≥ 0.80 |
 | ? | Neither ICC/weighted Kappa, nor Pearson's r determined |
 | - | ICC/weighted Kappa < 0.70 OR Pearson's r < 0.80 |
Validity | Â | Â |
Content validity | + | The target population considers all items in the questionnaire to be relevant |
 |  | AND considers the questionnaire to be complete |
 | ? | No target population involvement |
 | - | The target population considers items in the questionnaire to be irrelevant |
 |  | OR considers the questionnaire to be incomplete |
Construct validity | Â | Â |
- Cross-cultural validity | + | Original factor structure confirmed OR no important DIF |
 | ? | Confirmation original factor structure AND DIF not mentioned |
 | - | Original factor structure not confirmed OR important DIF |
- Structural validity | + | Factors should explain at least 50% of the variance |
 | ? | Explained variance not mentioned |
 | - | Factors explain < 50% of the variance |
- Hypothesis testing | + | (Correlation with an instrument measuring the same construct ≥ 0.50 OR |
 |  | at least 75% of the results are in accordance with the hypotheses) AND |
 |  | correlation with related constructs is higher than with unrelated constructs |
 | ? | Solely correlations determined with unrelated constructs |
 | - | Correlation with an instrument measuring the same construct < 0.50 OR |
 |  | < 75% of the results are in accordance with the hypotheses OR |
 |  | correlation with related constructs is lower than with unrelated constructs |
Responsiveness | Â | Â |
Responsiveness | + | (Correlation with an instrument measuring the same construct ≥ 0.50 |
 |  | OR at least 75% of the results are in accordance with the hypotheses |
 |  | OR AUC ≥ 0.70) AND correlation with related constructs is higher |
 |  | than with unrelated constructs |
 | ? | Solely correlations determined with unrelated constructs |
 | - | Correlation with an instrument measuring the same construct < 0.50 OR |
 |  | < 75% of the results are in accordance with the hypotheses OR AUC < 0.70 |
 |  | OR correlation with related constructs is lower than with unrelated constructs |
