| Abstract: | The aims of the present study were to determine the prevalence of non-suicidal self-injury (NSSI) in different eating disorder (ED) groups and morbid obesity, and to investigate whether NSSI in different ED/obesity groups co-occur with impulsivity. We assessed 535 individuals (365 ED and 170 obese patients) by means of a single item assessing lifetime NSSI and the Barratt Impulsivity Scale, which measures different dimensions of impulsivity. The results showed that 19.1% of the ED patients engaged in at least one act of NSSI during their life-time. NSSI was more prevalent in Bulimia Nervosa, Binge Eating Disorder, Eating Disorder Not Otherwise Specified compared to Anorexia Nervosa, Restrictive type and morbid obesity. Finally, ED/obese patients who engaged in NSSI scored significantly higher on the attentional, motor and non-planning subscales than patients without NSSI. The implications of these findings for the treatment of NSSI in binge/purging ED patients are discussed. |
