It is supported by two studies of one sample.School-based programs have also been developed to treat children who are survivors of abuse. This approach teaches children, parents, teachers, and other school staff how to identify the signs of child maltreatment as well as skills that can be helpful in preventing child maltreatment.Other forms of treatment include group therapy, play therapy, and  art therapy. Each of these types of treatment can be used to better assist the client, depending on the form of abuse they have experienced. Play therapy and art therapy are ways to get children more comfortable with therapy by working on something that they enjoy (coloring, drawing, painting, etc.). The design of a childs artwork can be a symbolic representation of what they are feeling, relationships with friends or family, and more. Being able to discuss and analyze a childs artwork can allow a professional to get a better insight of the child.Interventions targeting the offending parents are rare. Parenting training can prevent child abuse in the short term, and help children with a range of emotional, conduct and behavioral challenges, but there is insufficient evidence about whether it has impact on parents who already abuse their children. Abuse-focused cognitive behavioral therapy may target offending parents, but most interventions exclusively target victims and non-offending parents. Prevalence
Child abuse is complex and difficult to study.
Forced adoption
Removing children of ethnic minorities from their families to be adopted by those of the dominant ethnic group has been used as a method of forced assimilation. The Stolen Generations in Australia involved Australian Aboriginal and Torres Strait Islander children. In Canada, the Canadian Indian residential school system involved First Nations, Métis and Inuit children, who often suffering severe abuse. As part of the Uyghur genocide, in 2017 alone at least half a million children were also forcefully separated from their families, and placed in pre-school camps with prison-style surveillance systems and 10,000 volt electric fences.In Switzerland, between the 1850s and the mid-20th century, hundreds of thousands of children mostly from poor or single parents were forcefully removed from their parents by the authorities, and sent to work on farms, living with new families. They were known as contract children or Verdingkinder.Most of the children living in institutions around the world have a surviving parent or close relative, and they most commonly entered orphanages because of poverty. It is speculated that, flush with money, for profit orphanages are increasing and push for children to join even though demographic data show that even the poorest extended families usually take in children whose parents have died and it would be cheaper to aid close relatives who want to take in the orphans. Experts and child advocates maintain that separating children from their families often harm childrens development. During the One Child Policy in China, women were only allowed to have one child.
