BackgroundIn 2004, the U.S. Preventive Services Task Force determined that evidence was insufficient to support screening women for intimate partner violence (IPV).PurposeTo review new evidence on the effectiveness of screening and interventions for women in health care settings in reducing IPV and related health outcomes, the diagnostic accuracy of screening instruments, and adverse effects of screening and interventions.Data SourcesMEDLINE and PsycINFO (January 2002 to January 2012), Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews (through fourth quarter 2011), Scopus, and reference lists.Study SelectionEnglish-language trials of the effectiveness of screening and interventions, diagnostic accuracy studies of screening instruments, and studies of any design about adverse effects.Data ExtractionInvestigators extracted data about study populations, designs, and outcomes and rated study quality by using established criteria.Data SynthesisA large fair-quality trial of screening versus usual care indicated reduced IPV and improved health outcomes for both groups, but no statistically significant differences between groups. Fifteen fair- and good-quality studies evaluated 13 screening instruments, and six instruments were highly accurate. Four fair- and good-quality trials of counseling reported reduced IPV and improved birth outcomes for pregnant women, reduced IPV for new mothers, and reduced pregnancy coercion and unsafe relationships for women in family-planning clinics. Fourteen studies indicated minimal adverse effects with screening, but some women experienced discomfort, loss of privacy, emotional distress, and concerns about further abuse.LimitationTrials were limited by heterogeneity, lack of true control groups, high loss to follow-up, self-reported measures, and lack of accepted reference standards.ConclusionScreening instruments accurately identify women experiencing IPV. Screening women for IPV can provide benefits that vary by population, while potential adverse effects have minimal effect on most women.Primary Funding SourceAgency for Healthcare Research and Quality.
