Note. IUSC = Intolerance of Uncertainty Scale for Children; PPP = Positive Predictive Power; NPP = Negative Predictive Power; Selection Ratio = percentage scoring at or above cut score (note: does not reflect rate of “true” AD); Kappa = agreement between IUSC and ADIS-C/P after correcting for chance; OCC = Overall Correct Classification.

Sensitivity for parent-report cut scores above 59 were ≤ .50. Classification properties are reported in table only for cut scores in which associated sensitivity and specificity are both >.50.

Specificity for parent-report cut scores below 52 were ≤ .50. Classification properties are reported in table only for cut scores in which associated sensitivity and specificity are both >.50.
