To estimate the efficacy of a psycho-behavioral intervention in reducing intimate partner violence recurrence during pregnancy and postpartum and in improving birth outcomes in African-American women.
                We conducted a randomized controlled trial for which 1,044 women were recruited. Women were randomly assigned to receive either intervention (n=521) or usual care (n=523). Individually tailored counseling sessions were adapted from evidence-based interventions for intimate partner violence and other risks. Logistic regression was used to model intimate partner violence victimization recurrence and to predict minor, severe, physical, and sexual intimate partner violence.
                Women randomly assigned to the intervention group were less likely to have recurrent episodes of intimate partner violence victimization (odds ratio [OR] 0.48, 95% confidence interval [CI] 0.29-0.80). Women with minor intimate partner violence were significantly less likely to experience further episodes during pregnancy (OR 0.48, 95% CI 0.26-0.86, OR 0.53, 95% CI 0.28-0.99) and postpartum (OR 0.56, 95% CI 0.34-0.93). Numbers needed to treat were 17, 12, and 22, respectively, as compared with the usual care group. Women with severe intimate partner violence showed significantly reduced episodes postpartum (OR 0.39, 95% CI 0.18-0.82); the number needed to treat was 27. Women who experienced physical intimate partner violence showed significant reduction at the first follow-up (OR 0.49, 95% CI 0.27-0.91) and postpartum (OR 0.47, 95% CI 0.27-0.82); the numbers needed to treat were 18 and 20, respectively. Women in the intervention group had significantly fewer very preterm neonates (1.5% intervention group, 6.6% usual care group; P=.03) and an increased mean gestational age (38.2+/-3.3 intervention group, 36.9+/-5.9 usual care group; P=.016).
                A relatively brief intervention during pregnancy had discernible effects on intimate partner violence and pregnancy outcomes. Screening for intimate partner violence as well as other psychosocial and behavioral risks and incorporating similar interventions in prenatal care is strongly recommended.

                I. Prevention of abuse to women is a national priority; however, research has focused on identification of abuse rather than evaluating interventions. To evaluate the differential effectiveness of three levels of intervention, Brief, Counseling, and Outreach, a longitudinal study with repeated evaluation interviews at 2-, 6-, 12-, and 18-months postdelivery was completed at two urban public health prenatal clinics. The participants were 329 pregnant, physically abused Hispanic women. Both physical abuse and women's use of community resources were measured. Repeated measures ANOVA showed that severity of abuse decreased significantly (p < 0.001) across time for all intervention groups. Violence scores at 2-months postdelivery were significantly lower for the Outreach group (p < 0.05) compared to the Counseling only group, but not significantly lower than the Brief intervention group. At 6-, 12-, and 18-month follow-up there were no statistically significant differences among the intervention groups. The use of lay outreach for abused pregnant women merits further research. Abuse screening by itself, however, may be the most effective intervention to prevent abuse to pregnant women. This study assessed the initial feasibility, acceptability, and efficacy of an intervention aimed at reducing depression and posttraumatic stress disorder (PTSD) in a sample of low-income pregnant women with recent intimate partner violence (IPV). Fifty-four women were randomly assigned to the intervention or control group. The intervention consisted of four sessions during pregnancy and one "booster" session within 2 weeks of delivery. Based on principles of Interpersonal Psychotherapy, the intervention was designed to help participants improve their interpersonal relationships, including their social support networks, and master their role transition to motherhood. Assessments were administered at four time points (intake, 5-6 weeks post-intake, 2 weeks postpartum, 3 months postpartum) to assess for depression, PTSD, and IPV. The intervention did not significantly reduce the likelihood of a major depressive episode, PTSD, or IPV during pregnancy or up to 3-month postpartum. However, we found moderate effects for the intervention in reducing symptoms of PTSD and depression during pregnancy and a large effect for PTSD symptoms from pregnancy up to 3 months postpartum. This study suggests some initial support for our intervention. Larger randomized trials are needed to further examine the intervention both during and after pregnancy. To evaluate the effectiveness of an empowerment intervention in reducing intimate partner violence (IPV) and improving health status.
                Randomised controlled trial.
                Antenatal clinic in a public hospital in Hong Kong.
                One hundred and ten Chinese pregnant women with a history of abuse by their intimate partners.
                Women were randomised to the experimental or control group. Experimental group women received empowerment training specially designed for Chinese abused pregnant women while the control group women received standard care for abused women. Data were collected at study entry and six weeks postnatal.
                IPV [on the Conflict Tactics Scale (CTS)], health-related quality of life (SF-36) and postnatal depression [Edinburgh Postnatal Depression Scale (EPDS)].
                Following the training, the experimental group had significantly higher physical functioning and had significantly improved role limitation due to physical problems and emotional problems. They also reported less psychological (but not sexual) abuse, minor (but not severe) physical violence and had significantly lower postnatal depression scores. However, they reported more bodily pain.
                An empowerment intervention specially designed for Chinese abused pregnant women was effective in reducing IPV and improving the health status of the women. To determine whether individualized nursing case management can decrease stress among pregnant women at risk for or in abusive relationships.
                A multisite randomized controlled trial.
                Two prenatal clinics in the Pacific Northwest and rural Midwest.
                1,000 women who spoke English and were 13 to 23 weeks pregnant at time of recruitment.
                All intervention group women (N = 499) were offered an abuse video and had access to a nurse case manager 24/7. Additionally, participants at risk for or in abusive relationships received individualized nursing care management throughout the pregnancy.
                The most frequent nursing care management activities were providing support (38%) and assessing needs (32%). The nursing care management group received an average of 22 contacts, most (80%) by telephone and had a significant reduction in stress scores as measured by the Prenatal Psychosocial Profile. Compared to the control group, the differences were in the predicted direction, but not statistically different. A major finding was the choice by abused women to focus on basic needs and their pregnancies rather than the abuse, although all received safety planning.
                Pregnant women at risk for or in abusive relationships experience very stressful and complex lives. Nurses need to focus on the needs they identify, which may not be the abusive relationship. This pilot study examined the effectiveness of standard care and an empowerment intervention for abused pregnant women. Severe psychological abuse was most prevalent (42.2%) among this sample of women. Compared with women in the standard care group at the postintervention survey, women in the empowerment group were more likely to hide money (44.6% vs. 34.3%), establish a code with family or friends (19.6% vs. 16.2%), ask neighbors to call police if violence began (6.9% vs. 1.0%), had available bank account numbers (17.1% vs. 3.1%), had valuable jewelry (8.4% vs. 3.8%), and had available a hidden bag with extra clothing (9.0% vs. 3.1%). However, there was no statistically significant difference in health-related quality of life, adoption of safety behaviors, and use of community resources between women in the two groups. Simply asking pregnant women about abuse and offering referral could potentially interrupt and prevent further abuse. Despite the recognition of intimate partner violence (IPV) against women as a global health issue associated with significant morbidity and mortality, evidence-based treatment strategies for primary care settings are lacking.
                To assess the comparative safety behaviors, use of community resources, and extent of violence following two levels of intervention.
                A randomized, two-arm, clinical trial was completed in urban public primary care clinics with 360 abused women who assessed positive for physical or sexual abuse within the preceding 12 months. Two interventions were tested: a wallet-sized referral card and a 20-minute nurse case management protocol. Outcome measures were differences in the number of threats of abuse, assaults, danger risks for homicide, events of work harassment, safety behaviors adopted, and use of community resources between intervention groups over a 24-month period.
                Two years following treatment, both treatment groups of women reported significantly (p <.001) fewer threats of abuse (M = 14.5; 95% CI 12.6, 16.4), assaults (M = 15.5, 95% CI 13.5, 17.4), danger risks for homicide (M = 2.6; 95% CI 2.1, 3.0), and events of work harassment (M = 2.7; 95% CI 2.3, 3.1), but there were no significant differences between groups. Compared to baseline, both groups of women adopted significantly (p <.001) more safety behaviors by 24 months (M = 2.0; 95% CI 1.6, 2.3); however, community resource use declined significantly (p <.001) for both groups (M = -0.2; 95% CI -0.4,-0.2). There were no significant differences between groups.
                Disclosure of abuse, such as what happens with abuse assessment, was associated with the same reduction in violence and increase in safety behaviors as a nurse case management intervention. Simple assessment for abuse and offering of referrals has the potential to interrupt and prevent recurrence of IPV and associated trauma.
There is insufficient evidence to assess the effectiveness of interventions for domestic violence on pregnancy outcomes. There is a need for high-quality, RCTs with adequate statistical power to determine whether intervention programs prevent or reduce domestic violence episodes during pregnancy, or have any effect on maternal and neonatal mortality and morbidity outcomes.
