Self-Mutilation Reduction

  • Viewed as means of replacing emotional pain with “fake pain”, or physical pain that is under control of patient

    • Non-adaptive approach to distraction

  • To replace anger: Engage in physical task. Punch bo-bo doll, crush aluminum cans, make doll (cloth or play-doh) cut or tear instead of self. Exercise

  • Craving sensation, feeling depersonalized: Replace self-mutilation with something that hurts: Squeeze ice-cube for 1 minute. Put ice on spot you want to burn. Slap tabletop hard. Snap wrist with rubber band. Take cold bath

  • Wanting focus: Do other task (cleaning room, play computer game) that requires focus. Find simple object (paper clip) and try to name 30 uses for it

  • Wanting to see blood: Draw on self with red felt pen. Use food coloring bottle (red, naturally) and draw it across area you want to cut as if it were a knife.

    • Particularly in front lobes

    • Boredom tolerance

  • Seen particularly in small % of APD prone to violent behavior “Psychopaths”

Born or made l.jpg
Born or Made?

  • Evidence suggests APD largely inborn

    • “Conduct disorder” in children

  • May be exacerbated by environment

  • Difficult to tell

    • APD may lie about their background

    • Most people with negative backgrounds do not get APD

  • May be constant rate of APD in all cultures across all times

  • No evidence violent media increases APD prevalence (4% men, 1% women)
