The present study tests borderline personality symptoms as meditational pathways between child maltreatment and suicide potential among college students. A sample of 268 participants completed a questionnaire battery including demographic data, the Comprehensive Child Maltreatment Scale, Inventory of Altered Self-Capacities, and Personality Assessment Inventory. Results: Three multiple mediation models (1 for each type of child maltreatment) were conducted. Results demonstrated that the same set of borderline personality characteristics mediated the relations between each type of child maltreatment (i.e., physical abuse, emotional abuse, and neglect) and suicide potential. The mediating borderline symptoms were affective dysregulation, identity problems, and paranoia.
