Sensitivity, Specificity, Positive Predictive Value, and Negative Predictive Value for Adolescent Reward-Related Delta Predicting First-Onset Depressive Disorder at the 18-Month Follow-Up Assessment

Area Under the Curve	Cutoff	SEN	SPEC	PPV	NPV
.60	+2.0 SD	12.5	96.0	23.6	91.7
	+1.5 SD	17.5	91.8	17.4	91.8
	+1.0 SD	32.5	84.4	17.1	92.7
	+0.5 SD	42.5	75.2	14.5	93.0

Note. The reward-related delta was multiplied by −1 to produce the inverse relationship, such that more positive values indicated a reduced neural response to rewards. The table includes sensitivity, specificity, and positive and negative predictive values for a range of cut-offs for adolescent reward-related delta. PPV = positive predictive value; NPV = negative predictive value; SD = standard deviation; SEN = sensitivity, SPEC = specificity.
