Adaptation of Psychometric Tests for Identifying Borderline Personality Disorder Patients in India
Shalini Choudhary
The study aimed to use adapted versions of psychometric tests for identifying borderline personality disorder (BPD). It also examined the diagnostic efficiency of these measures. Data were collected on 22 BPD patients and 22 matched controls (non-Patients). The tests that were used included Millon’s Clinical Multiaxial Inventory (MCMI–III) Grossman Facet Scales Scale-C for Borderlines, and Personality Assessment Inventory-Borderline Features (PAI–BOR). McClean Screening Instrument (MSI) was selected for screening BPD and General Health Questionnaire - 12 (GHQ-12) for differentiating the non-clinical sample. Results estimated the diagnostic efficiency of the tests using logistic regression analysis (LRA). The diagnostic accuracy (DA) was estimated using sensitivity, specificity, and discriminatory ability. The DA of MCMI-III was 75% and its discriminatory ability was 87.7% which means this scale can differentiate well between patients and non-patients. The LRA showed that the sensitivity and specificity were 77.3% and 72.7% which is average. The DA of PAI-BOR was 79.1% and its discriminatory ability was 89.7% which means this scale can differentiate well between patients and non-patients. The sensitivity and specificity were 76.2% and 81.8%. The sensitivity of the scale is ‘average’ while its specificity is ‘good’. The DA of MSI-BPD was 97.7% and its discriminatory ability was 98.97% which means this scale can differentiate very well between patients and non-patients. The sensitivity and specificity were 100% and 95.5% which is ‘excellent’. Hence, among all the three, MSI is the best measure for identifying BPD.
