Objectives: Screening and diagnostic instruments for Borderline Personality Disorder (BPD) are not validated in people aged over 60. We report a pilot study examining the sensitivity and specificity of a de-novo screening instrument in older adults.
Methods: The BPD-OA screening tool incorporates DSM 5 and literature describing the expression of BPD in older adults. This study was conducted using a case control design. The Diagnostic Interview for Borderlines-Revised (DIB-R) and the McLean Screening Instrument for BPD (MSI-BPD) were used as comparators. Comprehensive assessment by psychiatric teams determined participants to be (i) BPD-positive (n = 22) or (ii) BPD-negative (gender matched; n = 21).
Results: The BPD-OA was the most sensitive instrument for discriminating older adult BPD from non-BPD participants (sensitivity = 0.82). No significant relationship was found between the BPD-OA score and age in BPD-diagnosed participants (r = -0.181, n = 21, p = .432). Participant age explained 3.2% of the variance in BPD-OA scores. Of the 21 BPD-negative participants, eight false positives experienced prominent mood disorders (specificity = 0.62).
Conclusions: The BPD-OA screening tool is clearly superior to instruments validated for use in younger people. Further refinement and evaluation will enhance its sensitivity and specificity.
Clinical implications: Detection of BPD in older adult care settings will improve outcomes for patients, families, and staff through better understanding and appropriate management and treatment strategies.
