Screening for personality disorder in incarcerated adolescent boys: preliminary validation of an adolescent version of the standardised assessment of personality – abbreviated scale (SAPAS-AV)

Table 2 ROC analysis of the SAPAS-AV and subgroup comparison of AUC

Sample	AUC (95% CI)	Standard error	Comparison of AUC difference
Sample	AUC (95% CI)	Standard error	p ¹
Whole sample at baseline (N = 80)	0.89^**** (0.80 to 0.95)	0.04	0.74
Whole sample at follow-up (N = 80)	0.90^**** (0.81 to 0.96)	0.03	0.74
Group 1 (n = 40)	0.89^**** (0.75 to 0.97)	0.06	0.93
Group 2 (n = 40)	0.89^**** (0.75 to 0.96)	0.05	0.93
Site 1 (n = 34)	0.86^**** (0.70 to 0.96)	0.07	0.47
Site 2 (n = 38)	0.92^**** (0.78 to 0.98)	0.05	0.47

Note. ^****AUC is significantly different from the non-informative line (AUC = 0.50) at the level of p < 0.0001. ¹Two-tailed z-test comparing differences between AUC for the two ROC-curves.
