| Metric | Meaning | Interpretation Benchmark | | :--- | :--- | :--- | | | Measures internal consistency of construct items. | Like Cronbach's alpha, a value > 0.7 generally indicates good reliability. | | Cronbach's Alpha | Traditional measure of scale reliability. | > 0.7 is typically considered satisfactory, indicating that items measuring the same construct are consistent with each other. | | Convergent Validity (AVE) | Average variance explained; how much variance a construct captures from its indicators. | > 0.5 suggests that the construct explains more than half of the variance in its items. | | HTMT (Heterotrait-Monotrait Ratio) | Estimate of the true correlation between two constructs. | < 0.85 or < 0.90 is recommended to confirm discriminant validity, indicating that a construct is truly distinct from others. | | MSV (Maximum Shared Variance) | Compares the AVE to squared inter-construct correlations. | For strong discriminant validity, the AVE should be greater than the MSV. | | ASV (Average Shared Variance) | Similar to MSV but based on average correlations. | For strong discriminant validity, the AVE should be greater than the ASV. |
