Comparison of sensitivity and specificity for depression diagnoses at the existing and optimal cut-points on the PHQ-9 and PHQ-2 in a sample of YAPHEU (n=77).

			Existing Cut-Point			Optimal Cut-Point
PHQ Form	DISC Diagnosis	AUC (95%CI)	Score	Sensitivity (95%CI)	Specificity (95%CI)	Score	Sensitivity (95%CI)	Specificity (95%CI)
PHQ-9	MDD (n⁺=11)^*	0.86 (0.77, 0.93)	10	0.73 (0.39, 0.94)	0.88 (0.78, 0.95)	7	0.91 (58.7, 99.8)	0.74 (62.0, 84.2)
PHQ-2	MDD (n⁺=11)^*	0.84 (0.73, 0.91)	3	0.73 (0.39, 0.94)	0.92 (0.83, 0.98)	3	0.73 (0.39, 0.94)	0.92 (0.83, 0.98)
