This research note reports data from a national survey of 213 domestic violence shelters regarding their teen dating violence (TDV) prevention efforts. More than half of the shelters reported that they provide TDV programing to at least 1/2 of the high schools in their communities; about 1/3 of shelters provide TDV programming to parents. Approximately 85% of shelters reported that they use or adapt a TDV curriculum. Shelters use information booths and Internet-based activities most often to increase public awareness, and they work through coalitions to advocate for TDV prevention efforts. This study is a first step toward documenting shelters’ TDV prevention work.
