Cost-Effectiveness of Health Care Interventions to Address Intimate Partner Violence: What Do We Know and What Else Should We Look for?

What Interventions are Cost Effective in Reducing Violence Against Women? A Scoping Review

PURPOSE

To systematically summarise the recent literature on the cost and cost effectiveness of interventions implemented to reduce violence against women (VAW) and decision frameworks guiding resource allocation.

METHOD

A scoping review of scholarly and grey literature on the cost-effectiveness and/or resource allocation for interventions addressing intimate partner violence (IPV), dating violence and non-partner sexual violence perpetrated against women aged 15 years and over. All settings and contexts were eligible, with papers published in English between 2010 and March 2023 included.

RESULTS

Nineteen papers fulfilled the inclusion criteria reporting the cost, cost savings and/or cost effectiveness of 24 interventions to prevent IPV and to a lesser extent, other forms of interpersonal violence. Among the 16 economic evaluation studies reviewed, four types of interventions were cost effective in multiple settings or studies, including community activism (Uganda, Ghana), gender transformative interventions with couples and individuals (Ethiopia, Rwanda), specific justice and law enforcement measures (USA) and a combined personnel training, support, and referral programme in General Practice in the UK. Other interventions were cost effective in a single study or had conflicting evidence. Three remaining papers conducted a partial evaluation or cost appraisal providing limited information on the cost or cost-savings of other implemented interventions. No frameworks on resource allocation for the prevention of VAW were identified.

CONCLUSION

While there is some evidence of cost effectiveness emerging for interventions implemented in specific contexts, overall, we find the recent evidence on costs and cost effectiveness of interventions for the prevention of VAW to be limited. Embedding economic evaluation in future effectiveness trials will build critical evidence needed to inform policy and resource allocation decisions based on the value-for-money of interventions. Modelling the benefits and costs of interventions to better understand the societal impacts of programmes at scale is a further research opportunity.

Economic Evaluation of an Intervention to Prevent Adolescent Dating Violence (Me & You)

Me & You: Building Healthy Relationships (Me & You) is a multilevel, technology-enhanced adolescent dating violence (DV) prevention program that aimed to reduce DV among ethnic-minority, early adolescent, urban youth. A group-randomized control trial of Me & You, conducted with 10 middle schools from a large urban school district in Southeast Texas in 2014-2015, found it to be effective in reducing DV perpetration and decreasing some forms of DV victimization. Economic evaluations of DV interventions are extremely limited, despite calls for more economic analyses to be incorporated in research. We help fill this gap by evaluating the cost-effectiveness from the payer and societal perspectives of implementing the Me & You program. Using cost data collected alongside the Me & You group-randomized trial, we computed incremental cost-effectiveness ratios. Our primary outcome was "any DV perpetrated" within 12 months of the intervention. We conducted a cost-benefit analysis beyond the intervention endpoint by using literature estimates of per-victim lifetime costs of DV. We performed sensitivity analyses to assess effects of uncertain parameters. Under the base-case scenario, the cost of the Me & You curriculum compared to the standard curriculum was $103.70 per-student from the societal perspective, and the effectiveness was 34.84 perpetrations averted, implying an incremental cost per perpetration averted of $2.98, which ranged from $0.48 to $73.24 in sensitivity analysis. Thus, we find the Me & You curriculum is cost-effective and cost-saving in most scenarios. Policymakers should carefully consider school-based DV prevention programs, and cost data should be regularly collected in adolescent prevention program evaluations.

Computerized intervention for reducing intimate partner victimization for perinatal women seeking mental health treatment: A multisite randomized clinical trial protocol

Intimate partner victimization (IPV) is a significant social and public health problem among perinatal women. Research suggests that 21% to 33% of perinatal women report IPV and there is an enormous amount of morbidity associated with IPV. Moreover, IPV places women at high risk for several psychiatric disorders, which transforms the perinatal period from an already challenging process into a potentially overwhelming one. Further, IPV and untreated mental illness during the perinatal period pose a dual risk of adverse physical and emotional outcomes for women and their developing fetus/infant. Given the high rates of IPV among women who seek mental health treatment, mental health clinics compared to other medical settings are more effective sites for focused case finding and intervention. Our team has successfully tested an innovative, computerized intervention, Strength for U in Relationship Empowerment (SURE). SURE is a brief, interactive program consistent with motivational interviewing and incorporates empowerment strategies. The proposed multisite randomized clinical trial (N = 186) will test whether SURE relative to control is associated with reduced IPV, greater positive affect and well-being, and greater perceived emotional support. We will also evaluate the role of theoretical mediators of empowerment and self-efficacy. Finally, we will estimate the resources needed and costs to deliver SURE, as well as the incremental cost effectiveness of SURE compared with treatment as usual. If SURE is found to be efficacious and cost effective, it can be easily integrated into clinical care and will fill a critical gap for a vulnerable, high-risk population.

Health-Sector Responses to Intimate Partner Violence: Fitting the Response Into the Biomedical Health System or Adapting the System to Meet the Response?

This study aims to analyze how middle-level health systems' managers understand the integration of a health care response to intimate partner violence (IPV) within the Spanish health system. Data were obtained through 26 individual interviews with professionals in charge of coordinating the health care response to IPV within the 17 regional health systems in Spain. The transcripts were analyzed following grounded theory in accordance with the constructivist approach described by Charmaz. Three categories emerged, showing the efforts and challenges to integrate a health care response to IPV within the Spanish health system: "IPV is a complex issue that generates activism and/or resistance," "The mandate to integrate a health sector response to IPV: a priority not always prioritized," and "The Spanish health system: respectful with professionals' autonomy and firmly biomedical." The core category, "Developing diverse responses to IPV integration," crosscut the three categories and encompassed the range of different responses that emerge when a strong mandate to integrate a health care response to IPV is enacted. Such responses ranged from refraining to deal with the issue to offering a women-centered response. Attempting to integrate a response to nonbiomedical health problems as IPV into health systems that remain strongly biomedicalized is challenging and strongly dependent both on the motivation of professionals and on organizational factors. Implementing and sustaining changes in the structure and culture of the health care system are needed if a health care response to IPV that fulfills the World Health Organization guidelines is to be ensured.

IMPRoving Outcomes for children exposed to domestic ViolencE (IMPROVE): an evidence synthesis

Background

Exposure to domestic violence and abuse (DVA) during childhood and adolescence increases the risk of negative outcomes across the lifespan.

Objectives

To synthesise evidence on the clinical effectiveness, cost-effectiveness and acceptability of interventions for children exposed to DVA, with the aim of making recommendations for further research.

Design

(1) A systematic review of controlled trials of interventions; (2) a systematic review of qualitative studies of participant and professional experience of interventions; (3) a network meta-analysis (NMA) of controlled trials and cost-effectiveness analysis; (4) an overview of current UK provision of interventions; and (5) consultations with young people, parents, service providers and commissioners.

Settings

North America (11), the Netherlands (1) and Israel (1) for the systematic review of controlled trials of interventions; the USA (4) and the UK (1) for the systematic review of qualitative studies of participant and professional experience of interventions; and the UK for the overview of current UK provision of interventions and consultations with young people, parents, service providers and commissioners.

Participants

A total of 1345 children for the systematic review of controlled trials of interventions; 100 children, 202 parents and 39 professionals for the systematic review of qualitative studies of participant and professional experience of interventions; and 16 young people, six parents and 20 service providers and commissioners for the consultation with young people, parents, service providers and commissioners.

Interventions

Psychotherapeutic, advocacy, parenting skills and advocacy, psychoeducation, psychoeducation and advocacy, guided self-help.

Main outcome measures

Internalising symptoms and externalising behaviour, mood, depression symptoms and diagnosis, post-traumatic stress disorder symptoms and self-esteem for the systematic review of controlled trials of interventions and NMA; views about and experience of interventions for the systematic review of qualitative studies of participant and professional experience of interventions and consultations.

Data sources

MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, EMBASE, Cochrane Central Register of Controlled Trials, Science Citation Index, Applied Social Sciences Index and Abstracts, International Bibliography of the Social Sciences, Social Services Abstracts, Social Care Online, Sociological Abstracts, Social Science Citation Index, World Health Organization trials portal and clinicaltrials.gov.

Review methods

A narrative review; a NMA and incremental cost-effectiveness analysis; and a qualitative synthesis.

Results

The evidence base on targeted interventions was small, with limited settings and types of interventions; children were mostly < 14 years of age, and there was an absence of comparative studies. The interventions evaluated in trials were mostly psychotherapeutic and psychoeducational interventions delivered to the non-abusive parent and child, usually based on the child’s exposure to DVA (not specific clinical or broader social needs). Qualitative studies largely focused on psychoeducational interventions, some of which included the abusive parent. The evidence for clinical effectiveness was as follows: 11 trials reported improvements in behavioural or mental health outcomes, with modest effect sizes but significant heterogeneity and high or unclear risk of bias. Psychoeducational group-based interventions delivered to the child were found to be more effective for improving mental health outcomes than other types of intervention. Interventions delivered to (non-abusive) parents and to children were most likely to be effective for improving behavioural outcomes. However, there is a large degree of uncertainty around comparisons, particularly with regard to mental health outcomes. In terms of evidence of cost-effectiveness, there were no economic studies of interventions. Cost-effectiveness was modelled on the basis of the NMA, estimating differences between types of interventions. The outcomes measured in trials were largely confined to children’s mental health and behavioural symptoms and disorders, although stakeholders’ concepts of success were broader, suggesting that a broader range of outcomes should be measured in trials. Group-based psychoeducational interventions delivered to children and non-abusive parents in parallel were largely acceptable to all stakeholders. There is limited evidence for the acceptability of other types of intervention. In terms of the UK evidence base and service delivery landscape, there were no UK-based trials, few qualitative studies and little widespread service evaluation. Most programmes are group-based psychoeducational interventions. However, the funding crisis in the DVA sector is significantly undermining programme delivery.

Conclusions

The evidence base regarding the acceptability, clinical effectiveness and cost-effectiveness of interventions to improve outcomes for children exposed to DVA is underdeveloped. There is an urgent need for more high-quality studies, particularly trials, that are designed to produce actionable, generalisable findings that can be implemented in real-world settings and that can inform decisions about which interventions to commission and scale. We suggest that there is a need to pause the development of new interventions and to focus on the systematic evaluation of existing programmes. With regard to the UK, we have identified three types of programme that could be justifiably prioritised for further study: psycho-education delivered to mothers and children, or children alone; parent skills training in combination with advocacy: and interventions involving the abusive parent/caregiver. We also suggest that there is need for key stakeholders to come together to explicitly identify and address the structural, practical and cultural barriers that may have hampered the development of the UK evidence base to date.

Future work recommendations

There is a need for well-designed, well-conducted and well-reported UK-based randomised controlled trials with cost-effectiveness analyses and nested qualitative studies. Development of consensus in the field about core outcome data sets is required. There is a need for further exploration of the acceptability and effectiveness of interventions for specific groups of children and young people (i.e. based on ethnicity, age, trauma exposure and clinical profile). There is also a need for an investigation of the context in which interventions are delivered, including organisational setting and the broader community context, and the evaluation of qualities, qualifications and disciplines of personnel delivering interventions. We recommend prioritisation of psychoeducational interventions and parent skills training delivered in combination with advocacy in the next phase of trials, and exploratory trials of interventions that engage both the abusive and the non-abusive parent.

Developing a programme theory to explain how primary health care teams learn to respond to intimate partner violence: a realist case-study

Background

Despite the progress made on policies and programmes to strengthen primary health care teams’ response to Intimate Partner Violence, the literature shows that encounters between women exposed to IPV and health-care providers are not always satisfactory, and a number of barriers that prevent individual health-care providers from responding to IPV have been identified. We carried out a realist case study, for which we developed and tested a programme theory that seeks to explain how, why and under which circumstances a primary health care team in Spain learned to respond to IPV.

Methods

A realist case study design was chosen to allow for an in-depth exploration of the linkages between context, intervention, mechanisms and outcomes as they happen in their natural setting. The first author collected data at the primary health care center La Virgen (pseudonym) through the review of documents, observation and interviews with health systems’ managers, team members, women patients, and members of external services. The quality of the IPV case management was assessed with the PREMIS tool.

Results

This study found that the health care team at La Virgen has managed 1) to engage a number of staff members in actively responding to IPV, 2) to establish good coordination, mutual support and continuous learning processes related to IPV, 3) to establish adequate internal referrals within La Virgen, and 4) to establish good coordination and referral systems with other services. Team and individual level factors have triggered the capacity and interest in creating spaces for team leaning, team work and therapeutic responses to IPV in La Virgen, although individual motivation strongly affected this mechanism. Regional interventions did not trigger individual and/ or team responses but legitimated the workings of motivated professionals.

Conclusions

The primary health care team of La Virgen is involved in a continuous learning process, even as participation in the process varies between professionals. This process has been supported, but not caused, by a favourable policy for integration of a health care response to IPV. Specific contextual factors of La Virgen facilitated the uptake of the policy. To some extent, the performance of La Virgen has the potential to shape the IPV learning processes of other primary health care teams in Murcia.

Between the empowered self and the social costs: Arab abused women's perceptions of their relationship with social workers in community health clinics in Israel

Abused women seek help from medicine services extensively. Qualitative interviews were conducted with 12 married Arab-Israeli abused women about their relationships with social workers in community health clinics. Analysis reveals that women's evaluation of the impact of encounters with social workers is bipolar. On one pole are the difficulties and stressors derived from the cultural limitations that are placed on their ability to bring changes. On the other pole are the benefits--awareness in coping with repressive social powers and empowerment as competent choosers. The discussion elaborates the conflicts and paradoxes inherent in the nature of the interventions with abused women in a collectivistic culture.

Psychological advocacy toward healing (PATH): study protocol for a randomized controlled trial

Background

Domestic violence and abuse (DVA), defined as threatening behavior or abuse by adults who are intimate partners or family members, is a key public health and clinical priority. The prevalence of DVA in the United Kingdom and worldwide is high, and its impact on physical and mental health is detrimental and persistent. There is currently little support within healthcare settings for women experiencing DVA. Psychological problems in particular may be difficult to manage outside specialist services, as conventional forms of therapy such as counseling that do not address the violence may be ineffective or even harmful. The aim of this study is to assess the overall effectiveness and cost-effectiveness of a novel psychological intervention tailored specifically for survivors of DVA and delivered by domestic violence advocates based in third-sector organizations.

Methods and study design

This study is an open, pragmatic, parallel group, individually randomized controlled trial. Women ages 16 years and older experiencing domestic violence are being enrolled and randomly allocated to receive usual DVA agency advocacy support (control) or usual DVA agency support plus psychological intervention (intervention). Those in the intervention group will receive eight specialist psychological advocacy (SPA) sessions weekly or fortnightly, with two follow-up sessions, 1 month and then 3 months later. This will be in addition to any advocacy support sessions each woman receives. Women in the control group will receive usual DVA agency support but no additional SPA sessions. The aim is to recruit 250 women to reach the target sample size. The primary outcomes are psychological well-being and depression severity at 1 yr from baseline, as measured by the Clinical Outcomes in Routine Evaluation–Outcome Measure (CORE-OM) and the Patient Health Questionnaire (PHQ-9), respectively. Secondary outcome measures include anxiety, posttraumatic stress, severity and frequency of abuse, quality of life and cost-effectiveness of the intervention. Data from a subsample of women in both groups will contribute to a nested qualitative study with repeat interviews during the year of follow-up.

Discussion

This study will contribute to the evidence base for management of the psychological needs of women experiencing DVA. The findings will have important implications for healthcare commissioners and providers, as well as third sector specialist DVA agencies providing services to this client group.

Applying Effective Corrections Principles (RNR) to Partner Abuse Interventions

Results of outcome evaluations of the domestic violence (DV) programs are not encouraging. Overall, the most optimistic conclusion is that these programs have only a modest impact on reducing repeat partner violence. Recently, there are calls for DV programs to “grow up,” adapt a paradigm shift, shed ideology, and determine how the maximum impact can be realized from work to reduce intimate partner violence (IPV). The following review examines why program results are so unconvincing and proposes a comprehensive framework to advance the field. Specifically, it recommends that applying the risk-need-responsivity (RNR) principles of effective corrections could substantially improve treatment results. Using this framework, the article identifies selected risk assessment tools to screen offenders into appropriate levels of service (the risk principle) and provides an extensive review of the literature on appropriate targets for change (the need principle). Problems with substance use (particularly alcohol abuse), emotion management, self-regulation, and attitudes supportive of partner abuse have substantial empirical support as factors related to IPV. There is weaker but promising support for targeting the impact of association with peers who are supportive of abuse of women, poor communication skills, and motivation to change abusive behavior patterns. Responsivity could be enhanced through incorporation of motivational interviewing techniques, the processes of change identified in the Transtheoretical Model, solution-focused and strength-based approaches, and attention to identity change and cultural issues. In addition, the review describes strategies to insure ongoing program integrity, a key factor in implementing effective interventions.

Cost-effectiveness of Identification and Referral to Improve Safety (IRIS), a domestic violence training and support programme for primary care: a modelling study based on a randomised controlled trial

OBJECTIVE

The Identification and Referral to Improve Safety (IRIS) cluster randomised controlled trial tested the effectiveness of a training and support intervention to improve the response of primary care to women experiencing domestic violence (DV). The aim of this study is to estimate the cost-effectiveness of this intervention.

DESIGN

Markov model-based cost-effectiveness analysis.

SETTING

General practices in two urban areas in the UK.

PARTICIPANTS

Simulated female individuals from the general UK population who were registered at general practices, aged 16 years and older.

INTERVENTION

General practices received staff training, prompts to ask women about DV embedded in the electronic medical record, a care pathway including referral to a specialist DV agency and continuing contact from that agency. The trial compared the rate of referrals of women with specialist DV agencies from 24 general practices that received the IRIS programme with 24 general practices not receiving the programme. The trial did not measure outcomes for women beyond the intermediate outcome of referral to specialist agencies. The Markov model extrapolated the trial results to estimate the long-term healthcare and societal costs and benefits using data from other trials and epidemiological studies.

RESULTS

The intervention would produce societal cost savings per woman registered in the general practice of UK£37 (95% CI £178 saved to a cost of £136) over 1 year. The incremental quality-adjusted life-year was estimated to be 0.0010 (95% CI -0.0157 to 0.0101) per woman. Probabilistic sensitivity analysis found 78% of model replications under a willingness to pay threshold of £20 000 per quality-adjusted life-year.

CONCLUSIONS

The IRIS programme is likely to be cost-effective and possibly cost saving from a societal perspective. Better data on the trajectory of abuse and the effect of advocacy are needed for a more robust model.
