Interpersonal Disconnection and Perceived Burdensomeness as Predictors of Suicide Risk in Borderline Personality Disorder

INTERPERSONAL DISCONNECTION AND PERCEIVED BURDENSOMENESS AS PREDICTORS OF SUICIDAL RISK IN BORDERLINE PERSONALITY DISORDER

Perceived burdensomeness is a stronger and more consistent predictor of suicide risk in borderline personality disorder than thwarted belongingness and is a clinically actionable treatment target.

Borderline personality disorder (BPD), characterized by pervasive interpersonal dysfunction, provides a clinically relevant context for applying the interpersonal theory of suicide (IPTS), which proposes that suicidal desire arises from the simultaneous presence of thwarted belongingness (TB) and perceived burdensomeness (PB). This study aimed to examine the evidence on the relationship between TB, PB, and suicide risk in adults with BPD and to identify clinical implications for risk assessment and treatment. PubMed and PsycINFO were searched for peer-reviewed studies examining IPTS constructs in relation to suicidal ideation and behavior in adult BPD samples; observational, longitudinal, and intervention studies using validated measures of TB and PB were included, while nonclinical populations were excluded. In clinical samples, BPD was consistently and uniquely associated with elevated levels of TB and PB. In a prospective study following 500 community-sampled adults over seven months, BPD symptoms predicted suicide risk indirectly through emotion regulation difficulties and subsequent elevations in PB, rather than directly. Perceived burdensomeness fully accounted for the relationship between affective dysregulation and suicidal ideation, whereas thwarted belongingness showed less consistent independent predictive value; a systematic review of 66 studies also identified PB as the most robustly supported IPTS predictor of suicidal ideation. The authors emphasize that systematic assessment of interpersonal cognitions may improve risk stratification in this population.
