People suffering from Borderline Personality Disorder (BPD) are characterized by impulsivity and memory impairment, in addition to problems with emotion regulation and their selfconcept. Because of the risky behaviour they show and the emotion regulation problems they have, they often get addicted to drugs. The aim of this study was getting to know the relationship between a Borderline personality disorder, drug abuse and prospective memory performance. It was expected that the group with BPD would show poorer performance on the prospective memory task requiring high inhibitory control than on the task requiring low inhibitory control. Moreover, it was expected that these differential effects would be stronger for people with BPD who report to have an additional addiction problem. In order to test this, a total of 20 patients of a clinic in Cologne were asked to participate in the study using a prospective memory task and several pen and paper tests concerning their diagnosis, mood, intelligence, cognitive capacity and drug abuse. The six male and 14 female participants were between the ages of 18 and 49 (M = 33.60). The results indicate that people suffering from BPD show no difference between high and low inhibitory control in prospective memory performance and that drug abuse was not moderating factor between BPD and prospective memory. Methodological, as well as theoretical explanations and practical implications are provided. Keywords: Borderline Personality Disorder, Prospective Memory, Drug Abuse
