The aim of the study was to investigate the dissociative process in a clinical sample of 78 patients suffering from cluster B personality disorders with or without substance abuse. The literature has defined the self-harm both as strategy of emotional avoidance (Chapman, Gratz, Brown, 2006) both as action termination of a dissociative state consequent to a state of analgesia (Matsumoto, Imamura, Chiba, 2008). Today the term dissociation can be referred to at the same time a defense mechanism, an altered state of consciousness, or the failure to capture or loss of integration between systems or mental modules (Van der Hart, Nijenhuis, Steele, 2006). Therefore it was decided to analyze the dissociative process related to the brooding, the emozional dysregulation and self-harm. The correlational statistical analysis and multiple linear regression data revealed significant and useful results for therapeutic intervention.
