Abstract
This research aimed to verify the relationship between traumatic events (TE) in childhood and the occurrence of self-injurious behavior in adolescents. The instruments used were the Childhood Trauma Questionnaire (QUESI) and the Deliberate Self-Injury Inventory - reduced (IAD-r). The sample was composed of 494 high school students of both genders and aged between 15 and 18 years old (M = 16.4). Of those, 58.5% declared to have suffered recurring emotional abuse and 19.0% declared to have suffered sexual abuse and 59.5% physical abuse. Regarding the practice of self-harm, 65.0% reported having already engaged in self-injurious behaviors. According to the Binomial Logistic Regression analysis, all types of TE were associated with the practice of self-injurious behaviors. The moderation analysis between the occurrence of childhood TE and self-injury showed no moderation by sex or age. However, regarding physical abuse, the moderating effect of age showed borderline statistical significance and indicated that younger adolescents, 15 and 16 years old, who suffered this type of abuse in childhood, were more susceptible to self-injurious behavior. Therefore, the high rates of TE and self-injury found in this research reveal the seriousness of the problem. It is hoped for this investigation to contribute to the development of interventions to prevent and control risk factors that affect children and adolescents.
