There is evidence of the high rates of victimization and polyvictimization in the Chilean population, as well as the negative consequences this has for the mental health of the victims. However, the level of victimization in adolescents of ethnic minorities is unknown. The aim of this study is to describe the prevalence of victimization and polyvictimization in Chilean adolescents belonging to an ethnic minority (aymara) and compare it with the prevalence in a population not belonging to an ethnic minority. It was also intended to determine the relationship between polyvictimization and post-trau-matic symptoms. We worked with a sample of 667 adolescents between 12 and 17 years of age (30,4% aymara y 69,6% not aymara) from the city of Arica, who were surveyed with the Juvenile Victimization Questionnaire (JVQ) and the Child Symptom Posttraumatic Scale (CPSS). Through the collected data it could be established that polyvictimization affects young aymaras and non-aymaras in similar ways; nevertheless, the impact of this victimization is different in young people who belong to the aymara community, who present a greater intensity of post-traumatic symptoms.
