Patterns of self-cutting: a preliminary study on differences in clinical implications between wrist- and arm-cutting using a Japanese juvenile detention center sample.
The present study was aimed to clarify the differences in clinical implications between wrist- and arm-cutting. Subjects were 201 delinquent adolescents (178 males and 23 females) who had been admitted to a detention center from February to March 2003. A self-reporting questionnaire and the Adolescent Dissociative Experience Scale (ADES) were given. Traumatic events and other self-injurious behavior were compared among four groups. In total, 33 (16.4%) subjects reported wrist- and/or arm-cutting. Of the females, 60.9% (n = 14) had experienced self cutting behaviors compared to 10.7% of males (n = 19). Subjects were divided into four groups; 'non-cutting' (NC: n = 168, 83.6%), 'wrist-cutting' (WC: n = 5, 2.5%), 'arm-cutting' (AC: n = 19, 9.5%), and 'wrist- and arm-cutting' (WAC: n = 9, 4.5%). WC, AC, and WAC groups reported early separation, bulling in school, and histories of sexual/physical abuse more frequently than NC group. WC and WAC groups reported suicidal ideation and suicide attempts more frequently than NC and AC groups. The ADES scores in AC and WAC groups were significantly higher than in those in NC group (P < 0.001), while the scores in WC were not different from NC groups. WC and WAC groups self-cut due to suicide idea more frequently than the AC group, while AC group self-cut due to anger expression more frequently than WC or WAC groups. Self-cutters experienced early separation, bullying in school, and sexual/physical abuse more frequently than-non-self-cutters. Arm-cutting behavior may predict dissociation, while wrist-cutting may involve with suicidality.
