Borderline personality disorder (BPD) is a serious personality disorder characterized by affective instability, impulsivity and interpersonal disturbance. Currently, intensive research is being conducted concerning the aetiology of BPD, including research on neurobiological, temperamental, psychosocial and cultural risk factors. This study focuses on psychosocial risk factors while other risk factors are taken into account in the discussion of the development of BPD. To our knowledge, no systematic review of the evidence-based medicine literature concerning this theme has been made thus far. However, understanding psychosocial risk factors of BPD is important in order to develop psychotherapeutic treatment models and methods. We provide a systematic review of the literature focusing on psychosocial risk factors for BPD. Utilizing this knowledge, we discuss how these data may be used when studying the development of borderline personality disorder and the treatment of borderline personality disorder.
