Comparison of AUCs between Pairs of Index Screening Instruments and the AUCs between Original and the Short-form of Each Instrument (N = 190).

* pa AUC1 was defined as the area under the curve of the first index screening instrument of the specific pair.b AUC2 was defined as the area under the curve of the second index screening instrument of the specific pair.c CI = confidence interview. All the reported 95% confidence intervals were constructed by bias-corrected bootstrap method with 2000 replicates (Efron & Tibshirani, 1994).d |AUC1 –AUC2| was defined as an absolute value of difference between AUCs of the specific comparison pair.e Mann-Whitney U- test was used to assess for equality of AUCs of the specific pair (E.R. DeLong, D.M. DeLong, & Clarke-Pearson, 1988).Comparison of AUCs between Pairs of Index Screening Instruments and the AUCs between Original and the Short-form of Each Instrument (N = 190).
