【 摘 要 】

The aim of this study was to analyze the predictive risk factors for self-harm in adolescents with and without suicidal ideation. 600 adolescents answered a questionnaire about self-harm and suicidal behaviors. A logistic regression analysis was conducted. Over half of the individuals with deliberate self-harm (DSH) presented significant suicide risk. There was a direct association between DSH and suicide attempts, with almost the totality of the adolescents with suicide attempts also reporting DSH. According to the prediction model, suicidal ideation and diversity of DSH behaviors are significant predictors of suicide attempts, with an augmentation in the diversity of DSH behaviors and suicidal ideation predicting suicide attempts. Depression and anxiety appeared also as significant predictors of suicide attempts in adolescent self-harmers. Considering that the majority of the sample was not from a clinical setting, an alarming finding was that one third of the total sample was at suicide risk. These results place DSH as a key variable for early intervention.
