Violence against children is a widespread phenomenon. Interpersonal violence within the family context is typical in childhood, whereas violence occurs more frequently in the leisure and peer context during adolescence, often involving new media. The risk for experiencing violence is associated with many different factors, for example the age, psychosocial context, and cultural background of a child. Data on the prevalence of violence vary by country, depending on the available documentation systems. It is estimated that the number of unreported cases is high. Meta-analyses comprising mainly retrospective self-report studies indicate prevalence estimates between 12 and 19% for neglect, physical, and sexual abuse. Emotional child abuse is reported far more often, with a prevalence as high as 36.3%. German studies, however, weren't able to replicate these international findings. Here, child emotional abuse is reported less often. Violence against children has many negative consequences for physical, emotional, and psychosocial development. Violence prevention therefore comprises different international and national programs and strategies, which are able to successfully reduce violence against children. Programs focusing on the promotion of adequate parenting behavior show especially promising results.
