Child sexual abuse (CSA) is a complex public health problem that has lifelong implications for children’s well-being. Interventions may provide children strategies to protect themselves against CSA, but few have been studied in Latin America. Bustamante et al. evaluated the impact of a 10-week educational program on the knowledge of CSA self-protection strategies among elementary students in Ecuador. Based on a questionnaire given at three time points, they found that the program increased and maintained CSA knowledge six months after the intervention across age groups.
