Interventions to Prevent or Reduce Violence Against Women and Girls : A Systematic Review of Reviews
description Violence against Women and Girls (VAWG) is a pervasive global problem. It is a violation of basic human rights and a drag on development. Much of the research to-date on the topic-including a major recent World Health Organization study to produce global prevalence rates has focused on better understanding the scale and nature of the problem. The present study builds on this body or research while shifting focus to synthesizing global evidence on potential solutions. This paper, a systematic review of reviews, breaks new ground by synthesizing evidence on the effects of VAWG prevention interventions. It examines the diversity of geographical context, the types of violence addressed, and the numerous approaches that have been used to combat VAWG. Additionally the review summarizes the quality of evidence on efficacy and effectiveness in order to highlight strengths and gaps of interventions on a global scale and could serve as a point of reference for those intending to undertake future design, implementation, and evaluation of interventions. This paper finds that knowledge of intervention impacts on VAWG prevention is growing, but is still highly limited. Nonetheless, a small but growing body of rigorously tested interventions demonstrates that preventing VAWG is possible and can achieve large effect sizes. The interventions with the most positive findings used multiple, well-integrated approaches and engaged with multiple stakeholders over time. They also addressed underlying risk factors for violence, including social norms regarding gender dynamics and the acceptability of violence. These examples point to the imperative of greatly increasing investment both in innovative programming in primary prevention, as well as in high-quality experimental and quasi-experimental evaluations to guide international efforts to end VAWG.
