  1. MAYSI-2 Massachusetts Youth Screening Instrument-second version, K-SADS-PL Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime version, Sens sensitivity rate, Spec specificity rate, PPV positive predictive value, NPV negative predictive value, AUC area under the curve, CI confidence interval
  2. *p < .05; ** p < .01; *** p < .001; ns not significant
  3. aThe optimal ‘caution’ cut-off scores are based on the difference between the sensitivity and specificity value to find the cut-off score with the lowest difference between both values
  4. bThe current cut-off scores are based on the results of the USA National Norms Study for the MAYSI-2 [17]
