Abstract
BACKGROUND: Borderline personality disorder is a major risk factor for suicidal behavior, yet prediction of suicide completion remains unclear. It has been proposed that impulsivity and aggression interact to increase suicide risk. Death by suicide in borderline personality disorder, then, may be the result of impulsivity, a core feature of the disorder, interacting with violent-aggressive tendencies. Using a case-control design, this study investigated clinical and behavioral risk factors for suicide completion in borderline personality disorder. METHOD: One hundred twenty subjects meeting DSM-IV criteria for borderline personality disorder, 50 controls and 70 who died by suicide between 2001 and 2005, were investigated by means of proxy-based interviews using structured diagnostic instruments and personality trait assessments. RESULTS: Borderline personality disorder suicides had fewer psychiatric hospitalizations and suicide attempts than borderline personality disorder controls. Borderline personality disorder suicides were also more likely to meet criteria for current and lifetime substance dependence disorders. They had higher levels of current and lifetime Axis I comorbidity, novelty seeking, impulsivity, hostility, and comorbid personality disorders, while exhibiting lower levels of harm avoidance. Most importantly, borderline personality disorder suicides were more likely to have cluster B comorbidity. Impulsivity and aggression interacted to predict suicide, though not after controlling for cluster B comorbidity. CONCLUSIONS: Borderline personality disorder individuals who die by suicide differ from those borderlines typically encountered in acute psychiatric settings. Our results suggest that the lethality of borderline personality disorder suicide attempts results from an interaction between impulsivity and the violent-aggressive features associated with cluster B comorbidity. Further, the anxious trait of harm avoidance appears to be protective against suicidal behavior resulting in death.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
