Interventions for Prevention of Intimate Partner Violence Against Women in Humanitarian Settings: A Protocol for a Systematic Review.

Introduction: Humanitarian emergencies and the number of people who are adversely affected are increasing. In such emergencies, the vulnerability of women and girls to gender-based violence increases signifi-cantly and they often experience high levels of intimate partner violence (IPV). There are a limited number of interventions to reduce gender-based violence (GBV) and IPV in the contexts of humanitarian emergencies, and there is uncertainty about the effectiveness of these preventive interventions. This is the protocol for a systematic review that will synthesize the evidence on interventions for primary or secondary prevention of IPV in humanitarian settings, and assess the effect of existing types of IPV-related interventions in these settings.

Methods and design: The PRISMA-P 2015 statement has been used to prepare this report. Studies published from January 2000 to January 2017 will be reviewed with no language limits. Any experimental, quasi-experimental, or controlled trials will be included. A combination of four key concepts, including "IPV" AND "population" AND "humanitarian setting" AND "intervention" will be used in the search and a variety of information sources will be used: (1) bibliographic databases; (2) special databases and grey literature; (3) and the reference lists of eligible studies. Two reviewers will independently screen articles, extract relevant data and assess study quality. Discrepancies will be resolved through consensus. Risk of bias will be assessed using the Cochrane Risk of Bias tool and the quality of evidence will be assessed using the CONSORT checklist. A narrative synthesis will be provided. If a sufficient number of studies are found, their results will be pooled using a random-effects meta-analysis. For dichotomous outcomes, summaries of intervention effects for each study will be provided by calculating risk ratios with 95% confidence interval. Standardized mean differences will be used for continuous outcomes.

Discussion: The review will be useful for IPV management policy and related planning. It will help researchers, policymakers and guideline developers with an interest in reducing violence against women among refugees, internally displaced persons (IDPs), and conflict-affected population.
