Pierced Identities: Body Modification, Borderline Personality Features, Identity, and Self-Concept Disturbances

Little is known about the connection between body modification and borderline personality disorder (BPD). This study investigated the relation between a wide range of body modification practices (piercing, tattooing, scarification, pubic hair removal, and cosmetic surgery) and BPD features, with a special focus on identity and identity dysfunction, in an adult community sample (N = 330). Results indicated BPD features were positively correlated with total number of body modifications and breadth of body modification practices endorsed, as well as, specifically, increased piercings, tattoos, and scarifications. Furthermore, identity problems (i.e., identity diffusion and low self-concept clarity) were associated with body modifications. Implications of these findings are discussed, including their heuristic value in understanding body modification in light of its connection to BPD (and particularly identity/self-concept functions).
