What is the Evidence Portal?

What is the Evidence Portal?

The ANROWS Evidence Portal is a living resource of evaluations of interventions from high-income countries that aim to address and end violence against women. It uses robust systematic review methodology to bring together this vast knowledge base in one place using interactive visualisations and accessible written summaries.

The Evidence Portal is designed to meet the needs of policy, practice, and research by promoting a collective understanding of which interventions might work (and which might not) and supporting better decision-making and implementation for interventions.

Ultimately, the Evidence Portal aims to ensure that the action we take in policy, practice and research to address and end violence against women is backed by a vast and quality evidence base.

What are the benefits of the Evidence Portal?

Impact evaluations of interventions can teach us a lot about “what works” so we can disentangle the best options to fund, implement, research and evaluate. The Evidence Portal saves you time and resources by bringing together this knowledge base in one place using interactive visualisations and accessible written summaries.

Our comprehensive and thorough processes mean that you can be confident that all available evaluation evidence that meets our eligibility criteria has been captured. The systematic search and screening will be updated regularly with new data. Currently, the Evidence Portal contains data from January 1994 up to and including December 2022.

The Evidence Portal adds a tool to your toolkit for places to find intervention evidence to address and end violence against women. It does some of the legwork for you by collating, categorising and interpreting evaluation evidence across a wide range of interventions, and intervention settings, modalities and implementers.

Search terms

This is an example of some of the search terms used in the ANROWS Evidence Portal systematic search. The ANROWS Evidence Portal is an online resource which allows users to search quickly and easily for information about what might work to address or end violence against women in high-income countries.

Our two key elements of the Evidence Portal are the Evidence and Gap Maps (EGMs) and the Intervention Reviews. EGMs are designed to capture the “big picture” in terms of quantity and types of existing research. Complementing the EGMs, our Intervention Reviews give you an overview of key information about an intervention and comment on the effectiveness of the intervention. Both incorporate evidence from primary quantitative, qualitative and systematic review evaluation research.

How can I use the Evidence Portal effectively?

Policy- and decision-making

Policymakers and decision-makers can use the EGMs for an accessible visual overview of the consolidated evidence on interventions designed to address and end violence against women.

The four EGMs are aligned with the domains outlined in the National Plan and function as a “shorthand” language that communicates consolidated evidence.

You can also search for and filter by specific interventions using the intervention search tool. By summarising key features of an intervention and focusing on the effectiveness of each intervention in achieving its outcomes, the intervention reviews can be used to inform the development of policy to address and end violence against women.

Practice and implementation

The Evidence Portal’s intervention reviews provide overviews and effectiveness measures, enabling practitioners and implementers to identify potentially effective interventions that may be appropriate for specific communities.

Research and evaluation

Researchers and evaluators, like practitioners and implementers, can use the intervention reviews to consider intervention applicability to different populations.

They can use the EGMs to identify gaps in the knowledge base and direct future research into crucial areas, and they can use the larger portal to inform funding and grant applications and literature reviews, and as a teaching resource to provide students with access to quality literature.

What are the limitations of the Evidence Portal?

Evaluations of interventions are one tool to determine what may work for your community or population. While there is much merit in bringing the evaluations together into one place, other forms of evidence should also be used to complement what the Evidence Portal can tell us about “what works”.

For example, knowledge from practitioners and people with lived experience may be captured in the Evidence Portal, but only when situated within an evaluation, so our picture of this knowledge may be incomplete. 

While some impact evaluation papers do comment on implementation and process evaluation components of interventions, these are not the focus of our Evidence Portal. Likewise, we don’t include the non-intervention evidence base into the broader literature on violence against women. Both forms of knowledge contribute to our understandings of the how and why an intervention may or may not be effective.

Some interventions, such as wide-scale policy changes or media campaigns, are more difficult to evaluate using traditional research models. This means there may be fewer evaluation papers on these types of interventions within the Evidence Portal. We’re also unable to comment on interventions that are yet to be evaluated or evaluations that are yet to be published (whether that be in traditional journal articles or other document types such as technical reports and dissertations).

We urge you to draw on other resources and knowledge to complement the Evidence Portal’s knowledge base for ending and addressing violence against women.
What is the Evidence Portal?
The ANROWS Evidence Portal is a living resource of interventions from high-income countries that aim to address and end violence against women, which is designed to:
  • Promote a collective understanding of which interventions might work – and which might not
  • Inform evidence-based policymaking
  • Support better decision-making and implementation when considering interventions.
The Evidence Portal is a key ANROWS resource designed specifically to meet the needs of policymakers and decision-makers, practitioners, researchers and funders. Below, we outline how each of these audiences might best use the resource.
How does the Evidence Portal work?
The Evidence Portal organises and synthesises impact evaluation and systematic review evidence. The Evidence Portal comprises two key complementary parts to visualise and summarise this evidence base: a series of evidence and gap maps, and intervention reviews.

The Evidence Portal is informed by gold-standard systematic review methodology used by the Cochrane network and the Campbell Collaboration, world leaders in synthesising and presenting evidence. We also use purposefully designed tools to determine the effectiveness of, and our confidence in, impact evaluation findings.

Evidence and gap maps
ANROWS has produced four EGMs that reflect the four domains of the National Plan to End Violence against Women and Children 2022–2032: prevention, early intervention, response, and recovery and healing.

These EGMs provide a visual overview of the evidence base and are designed to capture the “big picture” in terms of quantity and types of existing research. They incorporate evidence from primary quantitative and qualitative studies and systematic reviews. By categorizing evaluations according to the type of intervention studied and the outcomes measured, they can point stakeholders to research areas which currently have the most evidence, and those where gaps remain. This information is crucial for guiding the implementation and funding of evaluations. Each EGM also includes an indication of ANROWS’s confidence in the findings of the evaluations, based on our Study Confidence Rating Tool and the AMSTAR
Intervention reviews
Where the EGMs show the quantity and types of existing research, the intervention reviews take the important next step of providing overviews of interventions included in each EGM. These tell the user key information about an intervention, such as its delivery, resourcing, and setting characteristics. The intervention reviews also draw from quantitative impact evaluations to estimate how effective the intervention is in achieving its aims. These effectiveness estimates are based on our Evidence Rating Scale for Quantitative Studies.
Notably, the intervention reviews also draw on the evidence base (including qualitative evaluations), to enable the evidence portal to answer key questions such as:
  • Would this intervention work with specific First Nations community groups, people from culturally and linguistically diverse backgrounds, LBTQ and intersex people, older women and women with disability?
  • How do the research participants, particularly victims and survivors of violence, experience the interventions?
  • What would we need to consider if we were to implement this intervention in Australia?
Users can explore the intervention reviews via our searchable tool, which allows users to filter by type, nature, target or population of an intervention.
Since the Evidence Portal is a living resource, the collection of intervention reviews contained within it will continue to grow and be regularly updated. For further information regarding the intervention reviews, please see our Technical Report..
Policymakers and decision-makers
The EGMs will allow policymakers and decision-makers to see a collated and accessible visual overview of the available evidence on interventions designed to address and end violence against women. The four EGMs are aligned with the domains outlined in the National Plan, and function as a “shorthand” language that communicates consolidated evidence.
Policymakers and decision-makers can also search for and filter by specific interventions using the intervention search tool. By summarizing key features of an intervention and focusing on the effectiveness of each intervention in achieving its outcomes, the intervention reviews can be used to inform the development of policy to address and end violence against women.
Practitioners and implementers

In addition to providing overviews and effectiveness measures, the intervention reviews will enable practitioners and implementers to consider questions regarding intervention applicability to different populations; participant experiences of interventions; and the factors requiring consideration if the intervention were to be implemented in Australia. That is, the Evidence Portal will serve as a resource for identifying potentially effective interventions, underpinned by robust research that may “work” within specific communities, for practitioners and implementers to add to their existing “toolkit” of interventions.

Researchers and evaluators
Researchers and evaluators, like practitioners and implementers, can use the intervention reviews to consider intervention applicability to different populations; participant experiences; and what to consider if implementing the intervention in Australia.
The EGMs can be used to identify gaps in the knowledge base, guiding researchers and evaluators into crucial areas for future research. These users can also use the portal to inform their funding and grant applications and literature reviews, and as a teaching resource to provide students with access to quality literature.
What can’t I do with the Evidence Portal?

We need to be clear about what you can and cannot do with the Evidence Portal. While the portal provides a transparent way of collating and synthesising the effectiveness of existing interventions based on studies conducted in high-income countries, it is unable to comment on interventions that are yet to be evaluated, and does not synthesise the non-intervention evidence base within the broader field of research into violence against women. While the portal is not the answer to “what works” to reduce and respond to violence against women, it does provide an unbiased and comprehensive survey of the intervention literature. ANROWS does not necessarily endorse interventions included in the portal, and we urge all audiences to critically examine intervention suitability and applicability.
