This study will utilize geographic information systems (GIS) analyses to understand the spatial distribution of family violence and child maltreatment in San Diego, with a focus on the City Heights Planning Area. Small geographic areas of unusual risk for and protection from family violence and maltreatment will be identified through innovative spatial and survey analyses. This work will illuminate neighborhood processes shaping rates of family violence and maltreatment. A strong, collaborative team will utilize research findings, and extensive experience with effective parent training models, to design family violence prevention strategies applicable and efficient in small, high-risk geographic areas.
