This paper presents new perspectives on the conceptualization and treatment of Borderline Personality Disorder (BPD). This is achieved by first outlining current modes of classification, diagnosis, and treatment. Second, the current understanding is critiqued by deconstructing modern notions of selfhood and identity from which the BPD diagnosis is derived. A feminist critique is also explored as women comprise the majority of those diagnosed with BPD. Last, narrative therapy is discussed as a new treatment direction for BPD, and implications for clinical social work practice are discussed.
