Note. SBQ–14 = Suicidal Behaviors Questionnaire—14; DSHI = Deliberate Self-Harm Inventory; OR = odds ratio; SCID = Structured Clinical Interview for DSM–IV Axis II Disorders; BPD = borderline personality disorder; (Lo) = (Lack of; PAI = Personality Assessment Inventory; SenSeek = Sensation Seeking; Premed = Lack of) Premeditation; Persev = (Lack of) Perseverance; Urg = Negative Urgency; MPQ–SR = Multidimensional Personality Questionnaire—Stress Reaction scale.
Change in R2 is due to the new variables included in that step.
Increment in variance accounted for by the two BPD measures above and beyond other variables in the model.
