BACKGROUND We wanted to evaluate the benefi ts and harms of screening children in primary health care settings for abuse and neglect resulting from family violence by examining the evidence on the performance of screening instruments and the effectiveness of interventions.
METHODSWe searched for relevant studies in MEDLINE, PsycINFO, CINAHL, ERIC, Cochrane Controlled Trials Register, and reference lists. English language abstracts with original data about family violence against children focusing on screening and interventions initiated or based in health care settings were included. We extracted selected information about study design, patient populations and settings, methods of assessment or intervention, and outcome measures, and applied a set of criteria to evaluate study quality.
RESULTSAll instruments designed to screen for child abuse and neglect were directed to parents, particularly pregnant women. These instruments had fairly high sensitivity but low specifi city when administered in high-risk study populations and have not been widely tested in other populations. Randomized controlled trials of frequent nurse home visitation programs beginning during pregnancy that address behavioral and psychological factors indicated improved abuse measures and outcomes. No studies were identifi ed about interventions in older children or harms associated with screening and intervention.CONCLUSIONS No trials of the effectiveness of screening in a health care setting have been published. Clinician referrals to nurse home visitation during pregnancy and in early childhood may reduce abuse in selected populations. There are no studies about harms of screening and interventions.
INTRODUCTIONC hild abuse and neglect has been defi ned as "any recent act or failure to act on the part of a parent or caretaker which results in death, serious physical or emotional harm, sexual abuse or exploitation, or an act or failure to act which presents an imminent risk of serious harm."1 Approximately 1 million children are identifi ed as abused in the United States each year. 2 In 1999, reported abuse rates were 1,180 per 100,000 children with the highest rates for children age 3 years and younger. 3 An estimated 1,100 children died of abuse and neglect that year, approximately 1.62 deaths per 100,000 children. 3 Reported abuse likely captures only a fraction of all cases. 4 A large survey of adults indicated that 11% experienced psychological abuse, 11% physical abuse, and 22% sexual abuse during childhood.
5Frequently cited factors associated with child abuse and neglect include low income, 6-9 low maternal education, parental psychiatric disturbance, 10 and presence of a stepfather, 6 among others. 6,11 As the number of risk factors increases, the proportion of children maltreated also increases.
6Many health problems are associated with abuse and neglect. These problems include acute trauma, including death, unwanted pregnancy, and long-term physical and mental problems, such as depression, posttraumatic stress disorder, ...
