title: Construct Validity of the DSM-5 Section III Personality Trait Profile for Borderline Personality Disorder.
abstract: This study evaluated the nomological network of the borderline personality disorder (BPD) trait profile in the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM-5]) Section III. BPD symptoms include a variety of maladaptive thoughts and behaviors, and it is important to determine if the Section III trait operationalization for BPD captures these behavioral symptoms, as well as shows similar associations as the traditional Section II version with external criteria. For this purpose, we used a sample of 285 undergraduate students and conducted correlation and regression analyses to delineate the associations between Section III BPD traits and conceptually relevant external criteria. A Section III Total score was meaningfully associated with all criteria. Moreover, externalizing psychopathology tended to be most highly associated with disinhibitory Section III BPD traits, whereas internalizing psychopathology tended to have its strongest unique associations with traits reflective of negative affectivity. These results provide support for the construct validity of the trait profile for BPD in DSM-5 Section III.
