This study compared rates of intimate partner violence reports on a new, empirically-developed screening tool completed by 385 women in 2007 to those from an older tool completed by 420 women in 2006. Data were obtained from randomly selected medical charts across three health center locations, which were part of the same reproductive health care organization. Chi-square analyses were conducted to test associations between demographic characteristics and partner violence reports. Multiple regression analyses were used to compare odds ratios of disclosure by type of screening tool, adjusting for associated demographic factors associated with partner violence reports. Women completing the old and new tools were similar across all demographic characteristics. After adjusting for age and center location, women completing the new screening form were more than 2.5 times as likely to report any partner violence. When analyzed by mutually exclusive violence history categories, women completing the new screening form were over 2.5 times as likely to report past or current violence and over 4 times as likely to report experiencing both past and current violence. Findings suggest that implementing empirically developed brief screening tools for partner violence in reproductive health settings may elicit more disclosures from patients than more traditional tools.
