Driscoll C~~Brain K~~et al
This presentation discussed a study in which the strength of tension reduction experienced during self-mutilation was compared with the reduction in arousal experienced during intentional self-poisoning. 18 individuals who had intentionally overdosed & 18 self-mutilators participated in the study. Results incidated a reduction in arousal during the act of self-harm & immediately afterwards for both groups; this effect was greater among the self-mutilation group. Reasons for this were explored.
