‡ Ordinal standardised item Cronbach alpha.
Internal consistency was calculated by Cronbach's standardised item alpha.
The same conclusion was reached when we employed the ordinal standardised item alpha coefficient (Table 4).
In addition, we calculated for each standardised item its corrected item-total correlation, which should exceed 0.2[ 27] and calculated Crohnbach's alpha again excluding the item under study.
Alpha = 0.78 Standardised item Alpha = 0.79 Criterion validity was assessed by using a single-item assessment of perceived treatment need (Table 2).
Standardised item alpha = 0.79 Regarding criterion validity, the results indicated that adults who perceived a need for dental treatment had much higher OIDP scores than those who did not perceive dental treatment need (p < 0.001) (Table 5).
