Domestic violence (DV) programs, advocates, and survivors have long reported that survivors and their children who experience mental health- and substance use-related challenges face barriers in having their needs met. While DV programs do remarkable work with limited resources, programs report that survivors and their children increasingly come to their doors with more complex needs. To better understand these issues, NCDVTMH administered a nationwide needs assessment to DV program staff across US states, territories, and Tribal nations in 2019. The goal of this needs assessment was to learn more about DV programs’ capacity to meet the needs of survivors and their children with challenges related to substance use or mental health. This needs assessment was administered in partnership with the National Network to End Domestic Violence (NNEDV) and StrongHearts Native Helpline.
