Psychological characteristics of self-harming behavior in Korean adolescents

Recently, self-injury is drawing the attention of researchers and clinicians. The purpose of this study was to investigate the prevalence and psychological characteristics of adolescents who engage in self-harm and to examine the risk factors for engaging in this harmful behavior among Korean mid-adolescents. Participants were 784 adolescents aged 13-15 years. They completed self-report questionnaires that assessed (1) Non-Suicidal Self-Injury: the Self-Harm Questionnaire, Toronto Alexithymia Scale; (2) depression: Children's Depression Inventory; (3) adolescent-parent relationship: Parental Bonding Instrument; (4) peer attachment: Inventory of Parent and Peer Attachment; and (5) academic stress. Overall, 12.4% (n=97) of participants reported engaging in self-destructive behavior at least once in their lives. The primary reason for engaging in self-harm was to regulate negative emotions such as anger and sadness. As expected, the self-harm group showed statistically significant higher levels of academic stress, alexithymia, depression, and poor relationships with their parents and peers. Stepwise multiple regression analysis showed that alexithymia, depression, and peer relations were significant predictors of self-harming behavior. Given that the primary reason for engaging in self-harm is to cope with negative emotions, mental health professionals in school settings should regularly evaluate self-injurious behavior and provide prevention programs for adolescents at risk.
