Outline of research project

Borderline personality disorder (BPD) is defined by its core affective instability, in tandem with impulsive and erratic behaviours that are difficult to control (Linehan, 1993). Self-harm in particular plays a central role in BPD, to the extent it is one of the diagnostic criterion (American Psychiatric Association, 2000). It is not clear why some individuals choose to self-harm, however it is most commonly conceptualised as an affect regulation mechanism employed to make the individual feel better in some way, often as a distraction from painful and unwelcome emotions (Klonsky, 2007). This research programme aims to address weaknesses in the current literature by exploring what mechanisms contribute to self-harm behaviours in individuals with varying levels of BPD features. This has potentially far reaching implications for the theory and clinical practice, as understanding the nature and function of self-harm in BPD can lead to more effective avenues of research and practice.
