GAD1 and Anxiety: Results of the logistic regression (Table 8) confirmed that the sequential administration of the GAD-7 after the ESAS-A did not improve the predictability of an anxiety diagnosis beyond the ESAS-A or the GAD-7 as single screening tests (ESAS-A AUC = 0.55 vs. GAD-7 AUC = 0.57 ESAS-A + GAD-7 = 0.57).
