The science of safety


Relationship abuse is often complex and dangerous, making it difficult for survivors to make decisions while juggling competing priorities. Safety planning is the cornerstone of intimate partner violence interventions and is ideally an individualized process, taking into account each survivor’s unique situation.

Safety planning is most frequently accessed through traditional support services like DV hotlines, shelters, and domestic violence programs, yet the vast majority of abuse survivors never access these services, representing significant missed opportunities to reduce violence and its negative consequences. Therefore, myPlan was developed to expand access to safety planning.

Backed by research


In 2010, Johns Hopkins University developed and tested an early computerized version of the decision aid in domestic violence shelters. Survivors reported that the tool offered privacy to consider personalized safety options, informed them about danger in their relationship, and provided useful safety planning and resource information. After the promising feedback from the pilot, the next 6 years were spent developing the tool further based on survivor and advocate feedback and the effectiveness of the tool was tested in 2 longitudinal randomized controlled trials with over 1000 survivors, friends, and advocates across the country.

Designed through a series of multi-year research studies conducted by Johns Hopkins University School of Nursing, myPlan is the first interactive safety decision aid. The tool is accessible via a downloadable mobile app and web browser, and designed to assist intimate partner violence (IPV) survivors in identifying and navigating their own safe path forward.

Decision aids in health care settings have been shown to be effective in assisting patients to make difficult decisions about treatment options. By providing information and helping to clarify personal values, decision aids can assist someone to weigh risks and benefits to make informed decisions that impact their safety.

Developed by survivors for survivors

myPlan is the result of multiple research studies to develop and test a safety decision aid for effective use in different contexts relating to domestic abuse and intimate partner violence.

Using sound science, myPlan utilizes decision-making, risk assessment, and the empowerment framework that informs domestic violence advocacy and safety planning services. During every stage of myPlan’s development and testing, we centered lived experience experts, including DV survivors, friends of survivors, relationship violence advocates, and health providers. The effectiveness of myPlan was tested in multiple randomized controlled trials and contains the Danger Assessment, a validated risk assessment tool used for over 25 years by advocates, law enforcement, and other professionals.
