Safe mom, safe baby: a collaborative model of care for pregnant women experiencing intimate partner violence

Interventions for intimate partner violence during the perinatal period: A scoping review: A systematic review

Background

Intimate partner violence (IPV) is a prevalent global health problem. IPV that occurs before pregnancy often continues during the perinatal period, resulting in ongoing violence and many adverse maternal, obstetrical, and neonatal outcomes.

Objectives

This scoping review is designed to broadly capture all potential interventions for perinatal IPV and describe their core components and measured outcomes.

Search Methods

We conducted a search for empirical studies describing IPV interventions in the perinatal population in June 2022. The search was conducted in MEDLINE, EMBASE, PsycInfo, CINAHL, Cochrane Central Register of Controlled Trials, Web of Science, Applied Social Sciences Index & Abstracts, ClinicalTrials.gov and MedRxiv. Hand searching of references from select articles was also performed.

Selection Criteria

Included studies described an intervention for those experiencing IPV during the perinatal period, including 12 months before pregnancy, while pregnant or in the 12 months post-partum. The search encompassed January 2000 to June 2022 and only peer-reviewed studies written in either English or French were included. Included interventions focused on the survivor exposed to IPV, rather than healthcare professionals administering the intervention. Interventions designed to reduce IPV revictimization or any adverse maternal, obstetrical, or neonatal health outcomes as well as social outcomes related to IPV victimization were included.

Data Collections and Analysis

We used standard methodological procedures expected by The Campbell Collaboration.

Main Results

In total, 10,079 titles and abstracts were screened and 226 proceeded to full text screening. A total of 67 studies included perinatal IPV interventions and were included in the final sample. These studies included a total of 27,327 participants. Included studies originated from 19 countries, and the majority were randomized controlled trials (n = 43). Most studies were of moderate or low quality. Interventions included home visitation, educational modules, counseling, and cash transfer programs and occurred primarily in community obstetrician and gynecologist clinics, hospitals, or in participants' homes. Most interventions focused on reducing revictimization of IPV (n = 38), improving survivor knowledge or acceptance of violence, knowledge of community resources, and actions to reduce violence (n = 28), and improving maternal mental health outcomes (n = 26). Few studies evaluated the effect of perinatal IPV interventions on obstetrical, neonatal or child health outcomes.

Authors' Conclusions

The majority of intervention studies for perinatal IPV focus on reducing revictimization and improving mental health outcomes, very few included obstetrical, neonatal, and other physical health outcomes. Future interventions should place a larger emphasis on targeting maternal and neonatal outcomes to have the largest possible impact on the lives and families of IPV survivors and their infants.

Cultural Sensitivity in Interventions Aiming to Reduce or Prevent Intimate Partner Violence During Pregnancy: A Scoping Review

Intimate partner violence (IPV) around the time of pregnancy is a recognized global health problem. Ethnic minorities and immigrant pregnant women experiencing IPV require culturally responsive health services. The aim of this scoping review was to identify aspects of cultural sensitivity in interventions to prevent or reduce IPV among ethnic minorities and immigrant pregnant women in high-income countries. Eight databases were searched in November 2019. Any type of scientific research, quantitative, qualitative, or mixed methods studies regarding interventions against IPV among pregnant women were considered for inclusion. Resnicow et al.'s definition of cultural sensitivity was used to identify aspects of cultural sensitivity. Ten papers relating to nine interventions/studies met our inclusion criteria. These studies, which included randomized controlled trials, a mixed methods study, a program evaluation, and a longitudinal study, were conducted in Australia, Belgium, Norway, and the United States. Aspects of surface cultural sensitivity, including the translation of intervention content into the language of the target group(s) and the involvement of bilingual staff to recruit participants, were identified in eight studies. Deep structure aspects of cultural sensitivity were identified in one study, where the intervention content was pretested among the target group(s). Results that could be related to the culture-sensitive adaptions included successful recruitment of the target population. Three studies were planning to investigate women's experiences of interventions, but no publications were yet available. This scoping review provides evidence that culturally sensitive interventions to reduce or prevent IPV among immigrant pregnant women are limited in number and detail.

Dinámicas sociales en salud materna con énfasis en la Morbilidad Materna Extrema y aportes de la bioética en su comprensión

El propósito del presente artículo es analizar las dinámicas sociales en salud materna y los aportes de la bioética en su comprensión, haciendo énfasis en la Morbilidad Materna Extrema. Para ello, se llevó a cabo una revisión narrativa realizada en las bases de datos Scopus, Pubmed, Web of Science, Lilacs, Scielo y Google Scholar con la estrategia “Maternal Health” AND “Bioethics” OR “Social Justice”; incluyendo artículos en español, inglés y portugués, publicados en los últimos 25 años. En los resultados se incluyeron 79 manuscritos originales y 21 manuscritos de reflexión y revisión, que surtieron el análisis descriptivo al generar las siguientes categorías temáticas: 1. Necesidades de atención en salud y de cuidado; 2. Determinantes sociales, factores de riesgo y protectores; 3. Calidad de la atención, experiencias en el tratamiento y barreras de acceso; y 4. Perspectivas éticas y bioéticas de la salud materna. Como conclusión, se pudo afirmar que el abordaje bioético de la salud materna propone categorías de análisis como la justicia, la equidad, la autonomía y el acceso. Además de las condiciones de vida desde la pluralidad cultural y las consideraciones en cuanto a la comunicación y el lenguaje. Lo anterior, implica que desde los sistemas de salud se deben rediseñar los enfoques de atención en salud materna para abordar las vulnerabilidades y potenciar las capacidades de las mujeres.

Examining the Factors Associated With Sexual Violence Against Women in Sierra Leone: A Nationwide Cross-Sectional Study

In 2019, Sierra Leone declared national emergency over rape and other forms of sexual violence (SV), hence diverting resources from other issues to tackle SV. However, little is known about nationwide risk/protective factors for SV, and this has been a source of critique for the new policy. To fill this gap in knowledge, we investigated the factors for SV toward women using a nationally representative sample. We analyzed the 2013 Demographic and Health Survey (DHS) data, including 16,658 women, aged 15-49 years. The outcome was current SV, defined as being physically forced to have sexual intercourse within the last 12 months. We examined respondent's background, sexual activities, and experience of domestic violence (DV). Logistic regression analyses were performed using STATA/SE v.15.1, accounting for survey design and sample weights. Values of p less than .05 were considered statistically significant. ArcMap was used to demonstrate geographic distribution of SV cases. We found that about 258 (6.3%) women reported SV. In adjusted analysis, women in the north (than south; 2.88, 95% CI = [1.44, 5.75]) and women circumcised between the ages of 1 and 14 (1.67, 95% CI = [1.10, 2.54]) reported higher risk of SV, respectively. Women who had sex more than 25 times per year were 6.9 times more likely to report SV, compared with those with 1 to 24 times (6.91, 95% CI = [1.48, 32.19]). The odds of SV were 6 times higher among women who reported experiencing recent physical violence (5.86, 95% CI = [2.49, 13.80]) or history of SV (6.34, 95% CI = [2.57, 15.65]). In conclusion, this study adds to the literature by providing information on major factors associated with SV toward women in Sierra Leone using a nationally representative sample. Women in the north (Tonkolili), circumcised between the ages of 1 and 14, had sex more than 25 times per year, reported physical violence (12 months before the survey) and SV (ever forced to have sex) reported higher risk for current SV. While more research is needed, these findings will help inform the current emergency operations against SV in Sierra Leone.

Interventions Addressing Social Needs in Perinatal Care: A Systematic Review

Introduction: Health is impacted by a wide range of nonmedical factors, collectively termed the social determinants of health (SDoH). As the mechanisms by which these factors influence wellness and disease continue to be uncovered, health systems are beginning to assess their roles in addressing patient's social needs. This study seeks to identify and analyze clinic-based interventions aimed at addressing patients' social needs in perinatal care, including prenatal, antepartum, and postpartum care.

Methods: We conducted a search of six databases through May 2020 for articles describing screening or intervention activities addressing social needs in at least one SDoH domain as defined by Healthy People 2020. We required that studies include pregnant or postpartum women and be based in a clinical setting.

Results: Thirty-one publications describing 26 unique studies were identified. Most studies were either randomized-controlled trials (n=10) or observational studies (n=7) and study settings were both public and private. The mean age of women ranged from 17.4 to 34.1 years. Most studies addressed intimate partner violence (n=19). The next most common need addressed was social support (n=5), followed by food insecurity (n=3), and housing (n=2). Types of interventions varied from simple screening to ongoing counseling and case management. There was wide heterogeneity in outcomes investigated. Most IPV interventions that included counseling or ongoing support resulted in reduced IPV recurrence and severity. No intervention with only screening showed a reduction in rate of IPV.

Conclusion: This systematic review shines light on several avenues to support pregnant and postpartum women through interventions that embed acknowledgment of social needs and actions addressing these needs into the clinical environment. The results of this review suggest that interventions with counseling or ongoing support may show promise in alleviating social risk factors and improving some clinical outcomes. However, the strength of this evidence is limited by the paucity of studies. More rigorous research is imperative to augment the knowledge of social needs interventions, especially in domains outside of IPV.

A realist review of which advocacy interventions work for which abused women under what circumstances

BACKGROUND

Intimate partner abuse (including coercive control, physical, sexual, economic, emotional and economic abuse) is common worldwide. Advocacy may help women who are in, or have left, an abusive intimate relationship, to stop or reduce repeat victimisation and overcome consequences of the abuse. Advocacy primarily involves education, safety planning support and increasing access to different services. It may be stand-alone or part of other services and interventions, and may be provided within healthcare, criminal justice, social, government or specialist domestic violence services. We focus on the abuse of women, as interventions for abused men require different considerations.

OBJECTIVES

To assess advocacy interventions for intimate partner abuse in women, in terms of which interventions work for whom, why and in what circumstances.

SEARCH METHODS

In January 2019 we searched CENTRAL, MEDLINE, 12 other databases, two trials registers and two relevant websites. The search had three phases: scoping of articles to identify candidate theories; iterative recursive search for studies to explore and fill gaps in these theories; and systematic search for studies to test, confirm or refute our explanatory theory.

SELECTION CRITERIA

Empirical studies of any advocacy or multi-component intervention including advocacy, intended for women aged 15 years and over who were experiencing or had experienced any form of intimate partner abuse, or of advocates delivering such interventions, or experiences of women who were receiving or had received such an intervention. Partner abuse encompasses coercive control in the absence of physical abuse. For theory development, we included studies that did not strictly fit our original criteria but provided information useful for theory development.

DATA COLLECTION AND ANALYSIS

Four review authors independently extracted data, with double assessment of 10% of the data, and assessed risk of bias and quality of the evidence. We adopted RAMESES (Realist and meta-narrative evidence syntheses: evolving standards) standards for reporting results. We applied a realist approach to the analysis.

MAIN RESULTS

We included 98 studies (147 articles). There were 88 core studies: 37 focused on advocates (4 survey-based, 3 instrument development, 30 qualitative focus) and seven on abused women (6 qualitative studies, 1 survey); 44 were experimental intervention studies (some including qualitative evaluations). Ten further studies (3 randomised controlled trials (RCTs), 1 intervention process evaluation, 1 qualitative study, 2 mixed methods studies, 2 surveys of women, and 1 mixed methods study of women and staff) did not fit the original criteria but added useful information, as befitting a realist approach. Two studies are awaiting classification and three are ongoing.Advocacy interventions varied considerably in contact hours, profession delivering and setting.We constructed a conceptual model from six essential principles based on context-mechanism-outcome (CMO) patterns.We have moderate and high confidence in evidence for the importance of considering both women's vulnerabilities and intersectionalities and the trade-offs of abuse-related decisions in the contexts of individual women's lives. Decisions should consider the risks to the woman's safety from the abuse. Whether actions resulting from advocacy increase or decrease abuse depends on contextual factors (e.g. severity and type of abuse), and the outcomes the particular advocacy intervention is designed to address (e.g. increasing successful court orders versus decreasing depression).We have low confidence in evidence regarding the significance of physical dependencies, being pregnant or having children. There were links between setting (high confidence), and potentially also theoretical underpinnings of interventions, type, duration and intensity of advocacy, advocate discipline and outcomes (moderate and low confidence). A good therapeutic alliance was important (high confidence); this alliance might be improved when advocates are matched with abused women on ethnicity or abuse experience, exercise cultural humility, and remove structural barriers to resource access by marginalised women. We identified significant challenges for advocates in inter-organisational working, vicarious traumatisation, and lack of clarity on how much support to give a woman (moderate and high confidence). To work effectively, advocates need ongoing training, role clarity, access to resources, and peer and institutional support.Our provisional model highlights the complex way that factors combine and interact for effective advocacy. We confirmed the core ingredients of advocacy according to both women and advocates, supported by studies and theoretical considerations: education and information on abuse; rights and resources; active referral and liaising with other services; risk assessment and safety planning. We were unable to confirm the impact of complexity of the intervention (low confidence). Our low confidence in the evidence was driven mostly by a lack of relevant studies, rather than poor-quality studies, despite the size of the review.

AUTHORS' CONCLUSIONS

Results confirm the core ingredients of advocacy and suggest its use rests on sound theoretical underpinnings. We determined the elements of a good therapeutic alliance and how it might be improved, with a need for particular considerations of the factors affecting marginalised women. Women's goals from advocacy should be considered in the contexts of their personal lives. Women's safety was not necessarily at greatest risk from staying with the abuser. Potentially, if undertaken for long enough, advocacy should benefit an abused woman in terms of at least one outcome providing the goals are matched to each woman's needs. Some outcomes may take months to be determined. Where abuse is severe, some interventions may increase abuse. Advocates have a challenging role and must be supported emotionally, through provision of resources and through professional training, by organisations and peers.Future research should consider the different principles identified in this review, and study outcomes should be considered in relation to the mechanisms and contexts elucidated. More longitudinal evidence is needed. Single-subject research designs may help determine exactly when effect no longer increases, to determine the duration of longitudinal work, which will likely differ for vulnerable and marginalised women. Further work is needed to ascertain how to tailor advocacy interventions to cultural variations and rural and resource-poor settings. The methods used in the included studies may, in some cases, limit the applicability and completeness of the data reported. Economic analyses are required to ascertain if resources devoted to advocacy interventions are cost-effective in healthcare and community settings.

A qualitative process evaluation of a diabetes navigation program embedded in an endocrine specialty center in rural Appalachian Ohio

BACKGROUND

Diabetes in the United States has reached epidemic proportions and the people of Appalachia have been disproportionately affected by this disease. Strategies that complement standard diabetes care are critically important to mitigate the risk of complications, reduce health expenditures, and improve the quality of life of patients living in rural Appalachia. The purpose of this study was to conduct a qualitative process evaluation of a patient navigation program for diabetes after its first year of implementation.

METHODS

The process evaluation assessed how the Diabetes Navigation Program was delivered as well as how it was experienced by the navigators, providers, health administrators, and office staff at an endocrine specialty center in rural Appalachian Ohio. We employed total population sampling to conduct in-depth, face-to-face interviews with all providers, health administrators, staff, and navigators at a Diabetes Endocrine Center. Interviews were transcribed, coded, and analyzed via content and thematic analyses using NVivo 11 software.

RESULTS

Seventeen individuals (providers n = 5, health administrators n = 4, office staff members n = 3, and navigators n = 5) participated in in-depth, face-to-face interviews (age = 44.7 ± 11.6 years, 82.4% female, 94.1% white, 13.3 ± 9.6 years work experience). Fidelity of implementation: The navigation team carried out most of the activities denoted in the Work Plan, therefore the program was implemented somewhat successfully. Qualitative analysis revealed three themes: 1) The navigator addresses sources of health disparities: All participants described the role of the diabetes navigator as someone who is knowledgeable about diabetes and able to identify and address health disparities. 2) The navigators are the eyes in the community and the patients' homes: Navigators offered providers and clinic staff a rare glimpse into the personal lives of patients, which led to the identification of unrecognized barriers. 3) Difficulties with cross-system integration of services: Differences in the organizational culture and vision of the specialty center and navigation office contributed to systemic barriers.

CONCLUSIONS

Overall, this process evaluation highlights the importance of coordinating providers, health administrators, medical office staff, and navigators to address barriers to diabetes care. Forthcoming research is needed to document the clinical effectiveness and sustainability of the Diabetes Navigation Program in rural Appalachia.

The effect of training problem-solving skills for pregnant women experiencing intimate partner violence: a randomized control trial

Introduction

Intimate partner violence (IPV) in pregnancy is considered as an additional threat to the maternal/fetal health. The present study was aimed to investigate the effectiveness of training problem-solving skills on IPV against pregnant women.

Methods

The present randomized clinical trial was conducted on 125 and 132 women visiting the health centers of Tehran as the intervention and the control groups, respectively; samples were selected using random stratified cluster sampling. The intervention group underwent four problem-solving training sessions. Three months later, both groups completed the revised Conflict Tactics Scale questionnaire. Data were analyzed using SPSS v.16.

Results

The mean (SD) ages of the participants were 27.51 (4.26) and 27.02 (4.26) years, respectively, in the control and the intervention groups. The rates of the physical and psychological violence were significantly reduced after the intervention in the intervention group. Risk differences of the physical, psychological and sexual violence before and after the intervention were 3% (95% CI: -8.23 to14.13, P = 0.6), 1.5% (95% CI: -4.93 to 8.03, P = 0.6) and 4.8% (95% CI: -7.11 to 16.52, P = 0.4) in the control group and 8.8% (95% CI: -3.47 to 20.71, P = 0.1), 25.4% (95% CI: 15.77 to 34.66, P < 0.001) and 4.9% (95% CI: -7.38 to16.97, P = 0.4) in the intervention group, respectively.

Conclusion

It seems that training this skill as a part of the routine prenatal care could be effective in reducing intimate partner violence.

Navigation delivery models and roles of navigators in primary care: a scoping literature review

BACKGROUND

Systems navigation provided by individuals or teams is emerging as a strategy to reduce barriers to care. Complex clients with health and social support needs in primary care experience fragmentation and gaps in service delivery. There is great diversity in the design of navigation and a lack of consensus on navigation roles and models in primary care.

METHODS

We conducted a scoping literature review following established methods to explore the existing evidence on system navigation in primary care. To be included, studies had to be published in English between 1990 and 2013, and include a navigator or navigation process in a primary care setting that involves the community- based social services beyond the health care system.

RESULTS

We included 34 papers in our review, most of which were descriptive papers, and the majority originated in the US. Most of the studies involved studies of individual navigators (lay person or nurse) and were developed to meet the needs of specific patient populations. We make an important contribution to the literature by highlighting navigation models that address both health and social service navigation. The emergence and development of system navigation signals an important shift in the recognition that health care and social care are inextricably linked especially to address the social determinants of health.

CONCLUSIONS

There is a high degree of variance in the literature, but descriptive studies can inform further innovation and development of navigation interventions in primary care.

Implementation and maintenance of patient navigation programs linking primary care with community-based health and social services: a scoping literature review

Background

Since the early 90s, patient navigation programs were introduced in the United States to address inequitable access to cancer care. Programs have since expanded internationally and in scope. The goals of patient navigation programs are to: a) link patients and families to primary care services, specialist care, and community-based health and social services (CBHSS); b) provide more holistic patient-centred care; and, c) identify and resolve patient barriers to care. This paper fills a gap in knowledge to reveal what is known about motivators and factors influencing implementation and maintenance of patient navigation programs in primary care that link patients to CBHSS. It also reports on outcomes from these studies to help identify gaps in research that can inform future studies.

Methods

This scoping literature review involved: i) electronic database searches; ii) a web site search; iii) a search of reference lists from literature reviews; and, iv) author follow up. It included papers from Canada, the United States, the United Kingdom, Australia, New Zealand, and/or Western Europe published between January 1990 and June 2013 if they discussed navigators or navigation programs in primary care settings that linked patients to CBHSS.

Results

Of 34 papers, most originated in the United States (n = 29) while the remainder were from the United Kingdom, Canada and Australia. Motivators for initiating navigation programs were to: a) improve delivery of health and social care services; b) support and manage specific health needs or specific population needs, and; c) improve quality of life and wellbeing of patients. Eleven factors were found to influence implementation and maintenance of these patient navigation programs. These factors closely aligned with the Diffusion of Innovation in Service Organizations model, thus providing a theoretical foundation to support them. Various positive outcomes were reported for patients, providers and navigators, as well as the health and social care system, although they need to be considered with caution since the majority of studies were descriptive.

Conclusions

This study contributes new knowledge that can inform the initiation and maintenance of primary care patient navigation programs that link patients with CBHSS. It also provides directions for future research.

Approaches to improving the contribution of the nursing and midwifery workforce to increasing universal access to primary health care for vulnerable populations: a systematic review

BACKGROUND

Despite considerable evidence showing the importance of the nursing and midwifery workforce, there are no systematic reviews outlining how these cadres are best supported to provide universal access and reduce health care disparities at the primary health care (PHC) level. This review aims to identify nursing and midwifery policy, staffing, education and training interventions, collaborative efforts and strategies that have improved the quantity, quality and relevance of the nursing and midwifery workforce leading to health improvements for vulnerable populations.

METHODS

We undertook a structured search of bibliographic databases for peer-reviewed research literature using a focused review question and inclusion/exclusion criteria. The quality of retrieved papers was appraised using standard tools. The characteristics of screened papers were described, and a deductive qualitative content analysis methodology was applied to analyse the interventions and findings of included studies using a conceptual framework.

RESULTS

Thirty-six papers were included in the review, the majority (25) from high-income countries and nursing settings (32). Eleven papers defined leadership and governance approaches that had impacted upon the health outcomes of disadvantaged groups including policies at the national and state level that had led to an increased supply and coverage of nursing and midwifery staff and scope of practice. Twenty-seven papers outlined human resource management strategies to support the expansion of nurse's and midwives' roles that often involved task shifting and task sharing. These included approaches to managing staffing supply, distribution and skills mix; workloads; supervision; performance management; and remuneration, financial incentives and staffing costs. Education and training activities were described in 14 papers to assist nurses and midwives to perform new or expanded roles and prepare nurses for inclusive practice. This review identified collaboration between nurses and midwives and other health providers and organizations, across sectors, and with communities and individuals that resulted in improved health care and outcomes.

CONCLUSIONS

The findings of this review confirm the importance of a conceptual framework for understanding and planning leadership and governance approaches, management strategies and collaboration and education and training efforts to scale up and support nurses and midwives in existing or expanded roles to improve access to PHC for vulnerable populations.

Advocacy interventions to reduce or eliminate violence and promote the physical and psychosocial well-being of women who experience intimate partner abuse

BACKGROUND

Intimate partner abuse is common worldwide, damaging the short- and long-term physical, mental, and emotional health of survivors and children. Advocacy may contribute to reducing abuse, empowering women to improve their situation by providing informal counselling and support for safety planning and increasing access to different services. Advocacy may be a stand-alone service, accepting referrals from healthcare providers, or part of a multi-component (and possibly multi-agency) intervention provided by service staff or others.

OBJECTIVES

To assess the effects of advocacy interventions within or outside healthcare settings in women who have experienced intimate partner abuse.

SEARCH METHODS

In April 2015, we searched CENTRAL, Ovid MEDLINE, EMBASE, and 10 other databases. We also searched WHO ICTRP, mRCT, and UK Clinical Research Network (UKCRN), and examined relevant websites and reference lists with forward citation tracking of included studies. For the original review we handsearched six key journals. We also contacted first authors of eligible papers and experts in the field.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials comparing advocacy interventions for women with experience of intimate partner abuse versus no intervention or usual care (if advocacy was minimal and fewer than 20% of women received it).

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed risk of bias and undertook data extraction. We contacted authors for missing information needed to calculate statistics for the review and looked for adverse events.

MAIN RESULTS

We included 13 trials involving 2141 participants aged 15 to 65 years, frequently having low socioeconomic status.The studies were quite heterogeneous in terms of methodology, study processes and design, including with regard to the duration of follow-up (postintervention to three years), although this was not associated with differences in effect. The studies also had considerable clinical heterogeneity in relation to staff delivering advocacy; setting (community, shelter, antenatal, healthcare); advocacy intensity (from 30 minutes to 80 hours); and abuse severity. Three trials evaluated advocacy within multi-component interventions. Eleven measured some form of abuse (eight scales), six assessed quality of life (three scales), and six measured depression (three scales). Countries and ethnic groups varied (one or more minority ethnic groups in the USA or UK, and local populations in Hong Kong and Peru). Setting was associated with intensity and duration of advocacy.Risk of bias was high in five studies, moderate in five, and low in three. The quality of evidence (considering multiple factors such as risk of bias, study size, missing data) was moderate to low for brief advocacy and very low for intensive advocacy. Incidence of abuse Physical abuseModerate quality pooled data from two healthcare studies (moderate risk of bias) and one community study (low risk of bias), all with 12-month follow-up data, showed no effect on physical abuse for brief (< 12 hours) advocacy interventions (standardised mean difference (SMD) 0.00, 95% confidence interval (CI) - 0.17 to 0.16; n = 558). One antenatal study (low risk of bias) showed an association between brief advocacy and reduced minor physical abuse at one year (mean difference (MD) change - 1.00, 95% CI - 1.82 to - 0.18; n = 110). An antenatal, multi-component study showed a greater likelihood of physical abuse ending (odds ratio (OR) 0.42, 95% CI 0.23 to 0.75) immediately after advocacy (number needed to treat (NNT) = 8); we cannot exclude impact from other components.Low to very low quality evidence from two intensive advocacy trials (12 hours plus duration) showed reduced severe physical abuse in women leaving a shelter at 24 months (OR 0.39, 95% CI 0.20 to 0.77; NNT = 8), but not at 12 or 36 months. Sexual abuseMeta-analysis of two studies (n = 239) showed no effect of advocacy on sexual abuse (SMD - 0.12, 95% CI - 0.37 to 0.14), agreeing with the change score (MD - 0.07, 95% CI - 0.30 to 0.16) from a third study and the OR (0.96, 95% CI 0.44 to 2.12) from a fourth antenatal, multi-component study. Emotional abuseOne study in antenatal care, rated at low risk of bias, showed reduced emotional abuse at ≤ 12-month follow-up (MD (change score) - 4.24, 95% CI - 6.42 to - 2.06; n = 110). Psychosocial health Quality of lifeMeta-analysis of two studies (high risk of bias) showed intensive advocacy slightly improved overall quality of life of women recruited from shelters (MD 0.23, 95% CI 0.00 to 0.46; n = 343) at 12-month follow-up, with greater improvement in perceived physical quality of life from a primary care study (high risk of bias; MD 4.90, 95% CI 0.98 to 8.82) immediately postintervention. Depression Meta-analysis of two studies in healthcare settings, one at high risk of bias and one at moderate risk, showed that fewer women developed depression (OR 0.31, 95% CI 0.15 to 0.65; n = 149; NNT = 4) with brief advocacy. One study at high risk of bias reported a slight reduction in depression in pregnant women immediately after the intervention (OR 0.51, 95% CI 0.20 to 1.29; n = 103; NNT = 8).There was no evidence that intensive advocacy reduced depression at ≤ 12-month follow-up (MD - 0.14, 95% CI - 0.33 to 0.05; 3 studies; n = 446) or at two years (SMD - 0.12, 95% CI - 0.36 to 0.12; 1 study; n = 265). Adverse effectsTwo women died, one who was murdered by her partner and one who committed suicide. No evidence links either death to study participation.

AUTHORS' CONCLUSIONS

Results suggest some benefits from advocacy. However, most studies were underpowered. Clinical and methodological heterogeneity largely precluded pooling of trials. Therefore, there is uncertainty about the magnitude of benefit, the impact of abuse severity, and the setting.Based on the evidence reviewed, intensive advocacy may improve short-term quality of life and reduce physical abuse one to two years after the intervention for women recruited from domestic violence shelters or refuges. Brief advocacy may provide small short-term mental health benefits and reduce abuse, particularly in pregnant women and for less severe abuse.
