Table 3 Comparison of scores of assessment instruments between youths with and without a clinical diagnosis at first evaluation

From: Reasons and pathways of first-time consultations at child and adolescent mental health services: an observational study in Italy

Assessment instrument Subjects without a clinical diagnosis (mean + SD) Subject with a clinical diagnosis (mean + SD) AUC valuea (p)
CBCL Total Problem 39.9 (21.8) 45.3 (29.9) AUC = 0.54 (p = 0.404)
CBCL Performance Score 17.6 (5.5) 16.1 (6.0) AUC = 0.42 (p = 0.125)
Children Global Assessment Scale 74.1 (11.6) 63.0 (13.9) AUC = 0.72 (p < 0.001)
Clinical Global Impression Severity Index 2.1 (0.8) 3.2 (1.2) AUC = 0.78 (p < 0.001)
Health of the Nation Outcome Scale for Children & Adolescent 4.9 (3.9) 9.0 (5.5) AUC = 0.74 (p < 0.001)
  1. aAUC values are reported in order to quantify the performance of standardised assessment instruments (CBCL Total Problem; CBCL Performance Score; C-GAS; CGI; HoNOSCA). AUC is a non-parametric value and illustrates the performance of a binary classifier system; reported effect size intervals for AUC are: small effect sizes (0.528–0.556); medium effect sizes (0.584–0.638); large effect sizes. (0.714–0.760); very large effect sizes (above 0.760)
