“…For example, among the nine diagnostic criteria for BPD in DSM-IV (American Psychiatric Association, 1994), two entail self-harm (i.e., self-damaging impulsivity, suicidal behavior or gestures) while among the remaining DSM-IV personality disorders, only antisocial personality disorder has a criterion for self-harm (i.e., physical fights or assaults). Numerous authors have highlighted the importance of self-harm behavior in relation to BPD (Gunderson & Singer, 1975;Kernberg, Selzer, Koenigsberg, Carr, & Applebaum, 1989;Linehan, 1987;Schaffer, Carroll, & Abramowitz, 1982;Simeon, Stanley, Frances, Mann, Winchel, & Stanley, 1992;Walsh & Rosen, 1988). Mack (1975) described self-harm behavior as the behavioral specialty of those with BPD and other authors perceive this feature as a means to distinguish individuals with BPD from other severely disturbed individuals (Gunderson & Kolb, 1978;Gunderson, Kolb, & Austin, 1981;Perry & Klerman, 1980;Spitzer & Endicott, 1979).…”
