From the psychological standpoint, the anomalous behaviour of subjects with self-inicted disorders can be linked to various factors of both an “internal” and an “interpersonal” nature [11]. Internal factors include various dysmorphic symptoms, like tension, loneliness, anxiety, and aggression: in these cases, the self-injury is followed by a sense of relief and calm [21]. Other possible factors are to protect against the external world through pain [22], to interrupt feelings of derealization and dissociation, self-punishment, and reduce feelings of guilt [23], as well as to enhance self-esteem [11, 24]. In the latter case, the patient feels proud of the sense of power over his/her own body and of presenting to the doctor as an enigmatic, difcult case. Among “interpersonal” factors, the predominant one is the need for attention, in particular by the medical system, and the need to escape from problem­atic relationships and attacks [11].
