This suggests that specific items can be displayed in the CBA in a helpful way, so we have evidence, using the DIF analysis, that the specificity of the item had a positive effect on working with CBA.
Using this cut-off, a high sensitivity and specificity of the 15-item GDS has been reported [ 26, 27].
Using a cut-off of 3 or more errors, the sensitivity and specificity of the Six Item Screener for diagnozing dementia was 88.7 and 88.0, respectively [ 20].
Sensitivity and specificity of the 7-item modified Morisky scale for identifying lower vs. higher adherers was 91% and 50%, respectively, which was close to the estimates reported for the original 8-item scale at 93% and 53%, respectively.
The authors examined item-specificity of the trained items across each block.
We investigated three research questions: 1) Do socio-demographic and other psychopathology influence the screening properties of the IPDS? 2) What are the sensitivities and specificities of the IPDS items alone and in combination, and 3) What are the relationships of the 11 IPDS items and the concept of PDs as studied by latent variable path analysis?
Sensitivity and specificity of the dichotomous predictive items in the model-building were calculated.
However, due to the specificity of each item, the cold deck imputation method was preferred, and the missing values were replaced by the mean of the other participant's responses in the three questions [ 34].
The specificity of all items was higher than 0.88, and the sensitivity was always lower than 0.20 (table 3).
The specificity of each item (defined by the ability of the test to correctly identify patients that were exhibiting pain behaviours calculated by the ratio between the true negatives and the sum of the true negatives and false positives), was evaluated by investigating if that particular behaviour was present or not at TC in all observations from all evaluators, in all animals from all groups.
