Sensitivity of dental caries of deciduous teeth by item response theory (IRT) analysis.
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Two parameter logistic models were applied for analysis. Item discrimination (aj) indicated the slope of the item response curve shown in Figure 2, and the item difficulty (bj) indicated the rising phase of the curve. Lower values indicate high sensitivity for dental varies (easy-to-be dental caries) in both item discrimination and item difficulty. Higher values indicate high tolerance for dental varies (hard-to-be dental caries). |
