title: Concurrent validity of the Personality Assessment Inventory Borderline scales in patients seeking dialectical behavior therapy.
abstract: The purpose of this study was to explore the usefulness of the Personality Assessment Inventory (PAI; Morey, 1991) Borderline full scale (BOR) and subscales in the assessment of patients being evaluated for dialectical behavior therapy (DBT; Linehan, 1993). We administered 67 patients both the PAI and the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) Structured Clinical Interview for Axis II disorders (SCID-II; First, Spitzer, Gibbon, Williams, & Benjamin, 1997). Point biserial correlations showed a significant relationship between the presence of borderline personality disorder (BPD) and scores on the BOR and Schizophrenia (SCZ) scales. A regression analysis showed that among the BOR subscales, those measuring identity disturbance, self-harming behavior, and negative relationships were significantly related to the total number of SCID-II BPD criteria. Diagnostic efficiency statistics between the BOR scale and the number of SCID-II BPD criteria indicated that a T score cutoff of 65 optimally differentiates patients who do and do not meet criteria for BPD. The relationship between BOR and SCID-II BPD demonstrates the concurrent validity of the PAI and shows its usefulness in this setting.
