Note. GAD = youth meeting criteria for generalized anxiety disorder; NAD = non anxiety-disordered youth; SAD/SP = youth with other anxiety disorders; cPPP = corrected positive predictive power; OR = odds ratio.

Dashes in this column indicate OR is incomputable when specificity = 1.

OR is significant at p < .05 and cPPP > .70.
