Effectiveness of an Online Safety Tool for Canadian Women Experiencing Intimate Partner Violence

2019年4月23日 更新者：Marilyn Ford-Gilboe、Western University, Canada

Testing an Internet-based Safety Decision Aid for Women Experiencing Intimate Partner Violence

The purpose of this study is to assess the effectiveness of an interactive, online safety decision aid among diverse Canadian women who are experiencing intimate partner violence (IPV). The investigators will also explore how the online intervention works, and whether it has different effects for different groups of women.

详细说明

1 in 3 Canadian women experience IPV in their lifetimes. Over time, chronic stress of living in an abusive relationship has been shown to contribute to depression, anxiety and PTSD. Safety planning to reduce the risk of physical and emotional harm in abusive situations is one of the most widely recommended interventions for women in abusive relationship. However, fewer than 1 in 5 Canadian women access support from violence services to assist them in safety planning. Rural, Aboriginal, racialized, immigrant, sexual minority women and women who prioritize their privacy face particular barriers to accessing information and support for safety planning.

We adapted an interactive, online safety decision aid (SDA) recently developed and tested in the U.S. (Glass and colleagues, 2010) so that it applies to diverse groups of Canadian women, and extends the focus on emotional safety. The tool was revised based on a pilot testing for content and usability with 30 women (15 women who had experienced IPV and 15 service providers/experts). In this study, we test the effectiveness of this new tool, called "I CAN Plan 4 Safety" in a sample of 450 women from 3 provinces (ON, BC, New Brunswick). Women will be randomly assigned to complete either the personalized online safety decision aid (intervention) or an online tool which contains general risk and safety information (usual care control). Both tools are located on a confidential, password protected website. After initial completion of the online tools, they will be asked to login to the websites 3, 6 and 12 months later to complete standard outcome assessments. Women may access the information and resources in the online tools at any time for a 12 month period after they enrol in the study.

武器和干预

参与者组/臂
干预/治疗
实验性的：Personalized online Safety Decision Aid
Setting priorities for safety; Danger Assessment; Personalized Action Plan
行为的：Setting Priorities for Safety
Participants rate the importance of 5 priorities to decision-making about their unsafe relationship by comparing the relative importance of each pair of priorities. Weights for each priority are computed and provided to the woman, along with examples of safety strategies that fit with her top ranked priority.
行为的：Danger Assessment
Participants complete a calendar to show episodes of physical and/or sexual violence they have experienced in the past 12, along with 20 questions assessing risk of serious or lethal violence. A standardized weighted score is provided, along with a brief explanation about her level of danger and appropriate actions she may take.
行为的：Personalized Action Plan
Women create a tailored action plan for themselves by selecting strategies from 8 different groups, including those which are recommended to them based on their responses to previous questions.
有源比较器：General Online Risk/Safety Information
General Risk and Safety Information; Basic Emergency Safety Plan
行为的：General risk and safety information
Participants receive general information about the importance of priorities in making safety decisions and risk factors for intimate partner violence.
行为的：Basic Emergency Safety Plan
Participants are provided with a basic emergency plan including information about local DV resources. The information is not personalized but is consistent with online information which women could find on their own (usual care)
