Abstract

The aims of this study were to (1) investigate methods and functions of Non suicidal self-injury (NNSI); (2) examine association between NSSI and suicide probability in delinquent adolescents and adolescent with history of childhood maltreatment. Participants included 238 adolescents selected based on convenient sampling. The participants completed Non suicidal self injury behaviors checklist, Inventory of Non suicidal self- injury-functions and suicide probability scale. Results showed that 51% (31 from delinquent and 83 from another group) has at least 1 type of خودجرحی بدون NSSI behaviors which included cutting, burning, self-hitting, head-banging and rubbing. Suicide probability was significantly higher in adolescents with NSSI behaviors. Confirmatory factor analysis indicated group acceptance, marking distress, anti-suicide, self-affirmation, interpersonal boundaries, affect regulation and revenge as motivations extracted from Inventory of Statements about Self-Injury. Affect regulation, marking distress and group acceptance were motivations that predicted suicide probability
