Diagnostische Effizienz des McLean Screening Instrument für Borderline-Persönlichkeitsstörung in einer Stichprobe, die eine stationäre, störungsspezifische Behandlung in Anspruch nehmen möchte

Abstract

Borderline personality disorder (BPD) is considered as the most prevalent personality disorder in an inpatient setting. The McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) was developed to identify individuals with BPD reliably, valid and economically. To examine the discriminatory ability and diagnostic efficiency of the German version of the MSI-BPD in a sample with patients who meet probable BPD and seek a disorder-related inpatient treatment program. Based on a sample (N=298) containing 178 BPD-patients (60%), the area under the curve was AUC=0.70 (CI 95%: 0.64<AUC<0.76). Using the preferred cut-off point of>7. 84% of individuals with BPD (sensitivity) and 39% of individuals without BPD were identified correctly (specificity). Results suggest that a self-rated screening measure as the MSI-BPD should not be used in a sample with patients who meet probable BPD.
