Stop Child Abuse Through Effective Training and Augmented Reality (STOP) is an Erasmus+ KA2 Youth Project, financed by the European Commission (project number: 2019-2-HR01-KA205-061028). The project started in December 2019, with a duration of 26 months. STOP project aims to provide an innovative answer to the adverse childhood experiences that affect children and youth in Europe. Sexual abuse of children occurs far more often than previously acknowledged. Children are vulnerable and often ashamed and afraid to report any incidents. As a result, this form of abuse is the hardest to detect, and it has many harmful effects on children and youth. International studies (Barth et al.) reveal that approximately 20% of women and between 5 -10 % of men, report having been a victim of sexual violence as children.
