emotion. In other words, the individual would have some control or mastery over those emotions. Rational Cognitive Emotive Behavior Therapy is another available treatment and is intended to provide abused children and their adoptive parents with positive behavior change, corrective interpersonal skills, and greater control over themselves and their relationships. Parent–child interaction therapy was designed to improve the child-parent relationship following the experience of domestic violence. It targets trauma-related symptoms in infants, toddlers, and preschoolers, including PTSD, aggression, defiance, and anxiety. 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 child's 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 child's 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. According to the World Health Organization (WHO), estimates of the rates of child maltreatment vary widely by country, depending on how child maltreatment is defined, the type of maltreatment studied, the scope and quality of data gathered, and the scope and quality of surveys that ask for self-reports from victims, parents, and caregivers. Despite these limitations, international studies show that a quarter of all adults report experiencing physical abuse as children, and that 1 in 5 women and 1 in 13 men report experiencing childhood sexual abuse.
