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 < 0.001). Sensitivity was 0.88 and specificity ranged from 0.82 to 0.73 depending on the age-range. Correlation of the Ab-DIB's continuous score with the CIS was 0.42 (p < 0.001). In conclusion, The Ab-DIB's brief duration and psychometric properties suggest its utility in time-limited settings.
