Almost half of U.S. youth who experience violence, abuse or crime have had at least one of their victimisations known to school, police or medical authorities, according to a report in the January issue of Archives of Pediatrics and Adolescent Medicine, one of the JAMA/Archives journals.
'Childhood/adolescent abuse is frequently described as a hidden problem, and victimisation studies regularly have shown that much abuse goes undisclosed,' the authors write as background information in the article. 'The hidden nature of childhood victimisation has multiple sources. Clearly, children and adolescents are easily intimidated by offenders and fear retaliation. However, families, children and adolescents often wish to deal with crime and victimisation informally. They sometimes fear the consequences of disclosure to authorities in the form of interviews and police and court involvement. In other cases, they do not perceive that victimisations as something that would be of interest to authorities.'
To obtain national estimates of the degree to which authorities are aware of childhood victimisation, David Finkelhor, Ph.D., of the University of New Hampshire, Durham, and colleagues conducted a national telephone survey involving 4,549 children. Between January and May 2008, interviews were conducted with children and teens age 10 to 17 and the parents of children age 0 to 9 years. Participants answered questions about five types of victimisation: conventional crime, maltreatment, abuse by peers and siblings, sexual abuse and indirect exposure to violence (such as witnessing abuse).
A total of 58.3 percent of the children and teens reported at least one direct victimisation in the past year, including bullying. Of these, 45.7 percent had at least one victimisation that was known to authorities. The incidents about which authorities were aware tended to be more serious - for instance, officials knew about 69 percent of the cases of sexual abuse by a known adult, 73.5 percent of kidnappings and 70.1 percent of gang or group assaults. 'However, even emotional bullying (51.5 percent), neglect (47.8 percent) and theft (46.8 percent) were often known to authorities,' the authors write. The episodes most infrequently reported to authorities included peer and sibling assault, dating violence, sexual exposure/flashing and statutory rape.
School authorities were more likely to be aware of victimisation events, with 42.3 percent being aware compared with 12.7 percent among police and 1.8 percent among medical authorities. This result 'is understandable given how much time children and adolescents spend in school and interact with school professionals,' the authors write. 'Although police and medical authorities may conclude from these results that they are seriously underinformed about victimisation, it is not clear how much victimisation of children and adolescents merits the specialised involvement of these professionals.'
The findings represent an improvement from a comparable survey conducted in 1992, in which 25 percent of cases of victimisation among children age 10 to 16 years were known to authorities (compared with 50.6 percent among this age group in the current study). 'However, the study also shows that a considerable portion of childhood/adolescent exposure to victimisation is still unknown to authorities,' the authors write. 'The study suggests that outreach needs to be particularly enhanced toward boys, Hispanics and higher-income groups. It also suggests that disclosure promotion should be directed toward episodes that involve family members and peer perpetrators.'
