Reliability and diagnostic efficiency of the abbreviated-diagnostic interview for borderlines in an adolescent clinical population

Examine the reliability as well as the concurrent validity and diagnostic efficiency of the Abbreviated version of the diagnostic interview for borderlines revised (Ab-DIB) as a screening measure of borderline psychopathology in an adolescent clinical population. The Ab-DIB is a DIB-R-derived self-report covering the impulsiveness as well as the affect and cognitive components of the borderline construct. Its administration lasts 10 min. The Ab-DIB was tested on 139 suicidal youths for reliability and concurrent validity against the DIB-R and the Columbia Impairment Scale (CIS). Internal consistencies and test–retest Intra-Class-Correlations ranged from 0.80 to 0.86 and 0.77 to 0.95, respectively. ROC analysis yielded an area under the curve of 0.87 ( p
