Implications for practice and research

  • Children with disabilities are at increased risk for virtually every type of violence that has been measured in this population.

  • Healthcare providers and researchers need to take a more comprehensive, person-centered approach that focuses on the vulnerability to polyvictimisation and the interconnection among forms of violence for children with disabilities.

Context

Many forms of violence against children are all too common1 and the health consequences are dramatic. One in ten experience a violence-related injury every year.2 Violence is a leading cause of death among youth, and is ranked the second leading among all causes for adolescents aged 15–19.3 Behind these global statistics, however, are particularly vulnerable subgroups of children. One of the most vulnerable subgroups is children with disabilities, but data on this group are limited and scattered. Accurate data on the extent of violence against children with disabilities, and any heightened vulnerability relative to other children are essential for sound intervention, prevention and policy. Jones and colleagues’ systematic review compiles the best data on the prevalence and relative risk of violence among children with disabilities.

Methods

This careful and thorough systematic review involved the screening of more than 10 000 references found from multiple online and hand searches of articles including terms related to disability and victimisation. More than 800 full-text articles were reviewed, yet only 17 studies had usable data on the prevalence or relative risk of violence against children with disabilities. There were 16 that provided prevalence statistics, and 11 that had data on risk compared with children without reported disabilities. All the studies had been conducted in the USA or Europe, omitting many parts of the world with higher than average rates of both childhood disability and violence.

Findings

The prevalence of violence was disturbingly high, with more than 1 in 4 (27%) youth with disabilities experiencing physical violence and more than 1 in 6 (15%) experiencing sexual victimisation. Even more strikingly, children with disabilities were three to four times more likely to experience many types of violence than other children (ORs ranging from 2.88 to 4.56), including physical violence, sexual violence, emotional abuse and neglect. One particularly troubling finding is that the risk of sexual violence was significantly higher for children with psychological or intellectual disabilities compared with children with physical disabilities.

Commentary

The authors suggest that ‘the extent of violence against children with disabilities might extend further than has been assessed’. It is crucial to go beyond assessing the prevalence of specific violence types to consider the interconnections among forms of violence if the true burden of victimisation is to be understood.1 As Jones and colleagues note, at the time of their review, only one study was available on bullying, and none on important forms of violence such as exposure to domestic violence. Almost all the studies they found focused on parental maltreatment, but parental maltreatment is strongly associated with many other forms of victimisation. Indeed, more than one-third of maltreatment victims are also ‘polyvictims’, youth who have been victimised in multiple ways, often by multiple perpetrators in multiple settings.4 More recently, nationally representative data have shown that the risks of peer victimisation and property crime are also elevated for children with disabilities.5

The problems of emotional, behavioural and physical disabilities illustrate a key point regarding the interconnections among forms of violence that persistent underlying vulnerabilities explain not only high rates of individual forms of violence, but also why most forms of violence are interrelated.1 These interconnections call for a shift from interventions that focus on particular violence types to person-centred approaches that comprehensively assess children's safety across settings. This change can guide future research and intervention on violence against children with disabilities. A first step would be broadening assessment and screening; regardless of the presenting problem, all children should be assessed about their safety in all key settings: home, school and neighbourhood.
