A survivor’s decision to engage with formal services for experiences of intimate partner violence (IPV) is influenced by factors at the individual, interpersonal, and sociocultural levels. Understanding factors that facilitate survivors’ choice to seek services could be beneficial to formal service providers including community agencies, health professionals, and the criminal justice system, providing guidance toward the development and implementation of accessible services for survivors of IPV. This systematic review of the literature aims to identify key factors that facilitate survivors’ formal help-seeking. Ten electronic databases were searched for key terms related to help-seeking from formal services and facilitators of formal help-seeking. Articles were included in the review if the studies were conducted in the United States, focused on adults with experiences of IPV, and discussed facilitators of formal help-seeking. A total of 1,155 studies were initially identified, and after screening, 24 were included in the review. Seven factors were identified including provider knowledge, support, accessibility, desire to provide protection and to prevent future violence, and other factors such as knoweldge of and desire for services, policy factors, and personal factors. Findings demonstrate a need for more research on the facilitators of help-seeking among East Asian, South Asian, and Middle Eastern survivors living in the United States, as well as male-identified, trans, and gender nonconforming survivors. The review also indicates a need for culturally sensitive and accessible services that support survivors and the importance of raising awareness of the services and resources available for survivors.
