Objective: A considerable number of eating-disordered patients also display all kinds of self-injurious behaviours (SIB), which might be viewed as an indicator of psychopathological severity. Method: To test this hypothesis in 70 females admitted to a specialized treatment programme for eating disorders, a wide spectrum of psychopathological features was studied by means of self-reporting questionnaires: clinical symptomatology, personality disorders, aggression regulation, trauma history, dissociation and body experience. A comparison was made between patients with (n ¼ 27) and without SIB (n ¼ 43), as well as between patients with one (n ¼ 13) versus more types (n ¼ 14) of SIB. Results: In general, patients with SIB reported significantly more complaints or signs of anxiety, depression, hostility, cluster B personality disorders, feelings of anger, traumatic experiences, dissociation and negative appreciation of body size. The presence of more than one type of SIB was linked to a more pronounced clinical symptomatology and trauma history.
