ABSTRACT Potentially traumatizing events are common in adolescence, and these experiences have an impact on psychopathology. Furthermore, these events cumulate for certain individuals. More knowledge about the relationship between well-being and victimization experiences’ amount, type, and timing in adolescents is needed to understand the phenomenon of adolescent victimization. In this cross-sectional study, we investigated in a population-based sample of Finnish adolescents, whether victimization experiences associate with psychosocial well-being. The study sample comprised 5743 adolescents aged 15–16 years who filled in a questionnaire about 12 victimization experiences and psychosocial well-being. General Linear Model regression analyses were used for statistical analysis. A greater number of victimization experiences and recent timing, as well as type of victimization such as cyberbullying, were linked to problems related to psychosocial well-being. It is important to recognize current forms of youth victimization to identify the adolescents at risk for psychosocial distress and investigate on specific types of victimization.
