Resilience can be evidenced when an exposure to potentially traumatic event (PTE) has no negative impact on behavior. This study explored the effects of exposure to PTE applying a longitudinal design with 592 children (mean age 4 years) followed across three years. Children who had experienced a PTE and those who had not, were compared over time. Behavioral difficulties and prosocial behaviour for children experiencing PTE did not differ from those who had not experienced a PTE suggesting resilience among the exposed children. PTE in itself seems to carry minimal risk for symptoms of behaviour difficulties among preschool children.
